Cuckoos are birds that practice brood parasitism. Instead of raising her own young, a mother cuckoo finds another bird’s nest and lays her egg when the other is away. The other bird dutifully cares for the cuckoo egg until it hatches. The cuckoo hatchling, before it can even see, senses the touch of other eggs in the nest and ejects them by pushing against them with its body. Characterize the hatchling’s behavior, using Tinbergen’s first two questions for understanding a behavior. What is the stimulus for the behavior? What is the response? How does prior experience influence the behavior? Solution The cuckoo is the best known brood parasite an expert in the art of cruel deception. Its strategy involves stealth, surprise and speed. Cuckoos will not build their own nest. Female cuckoos will find another bird’s nest and in the absence of the parent she removes one of the original egg and removing it from nest laying her own egg. Cuckoos parasitize the nests of a large variety of bird species and carefully mimic the colour and pattern of their own eggs to match that of their hosts. To give proper parental care to their egg. The bright red mouth act as stimulus to the foster parent to feed it regularly. It carefully mimic the colour and pattern of their own egg to match with the hosts..

Chapter 2 Animals Where they live and How they get food
The document discusses animal life cycles and how babies resemble their parents. It covers how different types of animals, such as birds, spiders, insects, fish, frogs, and mammals, develop from eggs or live births. Their life cycles often involve stages from embryo to adult. Babies learn skills both through instincts as well as watching and learning from parents and other adults of their species. Animals continue learning through making mistakes and practicing behaviors important for survival.
Do Fleas Fly.pdf
Fleas are among the world’s most common pest insects. Even if you do not live in a flea-infested house, you can still be bitten by these creatures, as they are commonly found outside as well as inside. These blood-sucking pests are also carriers of diseases which can spread rapidly. Thankfully, you no longer have to face a flea epidemic at home. The good news is that you can actually get rid of fleas using natural methods. In this article, we will cover everything you need to know about fleas, from their life cycle to the best home remedies for getting rid of them and their eggs. If you’re ready to get started and learn how to get rid of fleas and their eggs in your home.
Stick insects
These insects are named for their interesting camouflage technique. They blend into woody plants where they feed. Stick insects even imitate twigs swaying in the wind by rocking back and forth as they move. However, the size is a lot different from a real twig as they are a lot smaller – especially when they are babies, we could hardly spot ours.

reproductive adaptation in insects.pptx
Insects have evolved many specialized reproductive and survival strategies that allow them to thrive despite their small size and vulnerability. They employ various courtship behaviors like songs, dances, and gifts to attract mates. After mating, some insects exhibit bi-parental care where both parents care for offspring, while others rely on maternal or paternal care alone. Additional survival strategies include migration to escape threats, entering dormant diapause stages to survive unfavorable conditions, and polymorphism which divides labor in social species to utilize resources efficiently. These diverse adaptations help insects reproduce successfully and assure their survival in different environments.
Interactions in Communities
This document discusses different types of interactions between organisms: symbiosis, predation, and competition. It defines mutualism, commensalism, and parasitism as the three types of symbiotic relationships where organisms of different species have a close relationship. Predation is defined as one organism hunting and eating another. Competition occurs when organisms attempt to use the same resource. The document provides examples of different species demonstrating each type of relationship and how competition can be reduced by occupying different niches.

The document describes various examples of symbiotic relationships between different organisms, and asks the reader to identify the type of symbiosis in each case. The three main types are defined as mutualism, commensalism, and parasitism. Mutualism benefits both organisms, commensalism benefits one without affecting the other, and parasitism benefits one organism at the expense of the other.

(1) Butterflies undergo a process of complete metamorphosis, changing from an egg to a caterpillar, then a pupa, and finally an adult butterfly. (2) As caterpillars, they eat voraciously and molt multiple times as they grow. (3) Within the pupa stage, the caterpillar's structure is broken down and rearranged into the wings and body of the adult butterfly. (4) Adult butterflies engage in various activities like feeding, basking, mating, egg-laying, hibernating, migrating, and camouflaging to survive and reproduce.

Crazy Cuckoos!
Parasitism describes a symbiotic relationship where one organism, the parasite, benefits while harming the other, the host. Common human parasites include ticks, tapeworms, and roundworms. Cuckoos are avian brood parasites that lay their eggs in the nests of other bird species like reed warblers. The cuckoo chick then evicts the host's eggs and chicks from the nest to monopolize all food from the host parents.
March 5
1. The parasitic relationship described is ticks feeding on a dog.
2. Single-celled organisms can reproduce asexually by creating identical new cells without combining genes from two parents.
3. The body system whose primary function is the continuation of the species is the reproductive system.
Describing A Cycle
The document describes the 8-stage life cycle of a butterfly. It begins with an egg being laid on a leaf, then hatching into a larva. The larva eats leaves as a caterpillar. It then forms a chrysalis and hangs as a pupa for two weeks before emerging as a butterfly with crumpled wings. Finally, the new butterfly hangs until its wings dry and then flies away.
Diptera (Flies).pptx
The document discusses the order Diptera, or true flies. It notes that Diptera are characterized by having one pair of wings, with the hind wings reduced to knob-like structures called halteres. Flies range in size from less than 1mm to over 7cm. There are over 125,000 known fly species worldwide. Flies can be found in most habitats and play both beneficial and harmful roles in ecosystems.
Reproduction In Animals
This document summarizes reproduction in different types of animals. It explains that mammals like humans and bears give birth to live young that they nourish and care for. Birds lay eggs that parents incubate until the chicks hatch. Frogs lay many eggs that become tadpoles and later frogs. Insects undergo complete metamorphosis from egg to larvae to pupa to adult. Butterflies pass through the stages of egg, caterpillar, pupa and adult. Fish, snakes and turtles lay eggs outside their bodies that hatch into young.
Project_1_treetopinsects_SciencePub
This document provides instructions for a student activity to collect and classify insects found in three different species of trees. Students will use beating sheets to collect insects from selected tree branches. The insects will then be cooled and examined under magnification to identify them to the order level using a dichotomous key. By comparing the types and quantities of insects found on each tree, students can investigate differences in the insects inhabiting various tree species. The activity aims to introduce students to insect collection and classification.
Entomology
Forensic entomology uses insects and their life cycles to help determine important details for investigating crimes and death investigations. The succession of insects that colonize a corpse follows predictable stages and can help estimate the post-mortem interval, which is the time since death. Temperature affects the development and growth of insects, so understanding these relationships is important for using insects to estimate timelines in forensic investigations.
Monarch butterflies show
The monarch butterfly goes through four life stages: egg, caterpillar, pupa, and butterfly. As a caterpillar, it eats swan plant leaves which make it toxic to protect it from predators. It then forms a chrysalis and undergoes metamorphosis to emerge as an adult butterfly. The short-lived butterfly will then lay eggs on swan plants to restart the cycle. The monarch butterfly is known for its long annual migration patterns in North America, while in New Zealand they do not migrate far from where they hatch.
Fungi
Leaf cutter ants act as farmers by cutting leaves and growing fungus in special underground chambers. The ants crush and chew the leaves to make mulch, then place the mulch in growing chambers and add fungus strands. They help the fungus grow by removing harmful bacteria and mold. Finally, the ants eat the fungus. Both the ants and fungus benefit from this relationship - the ants make fungus farms and the fungus provides food for the ants.
Butterflies
The document summarizes the four life cycle phases of a butterfly:
1. Eggs are laid on leaves and hatch into caterpillars.
2. Caterpillars molt several times as they eat voraciously.
3. When fully grown, the caterpillar attaches itself and forms a chrysalis where it undergoes metamorphosis.
4. An adult butterfly emerges from the chrysalis with wet wings that soon harden and allow it to fly while feeding on nectar and searching for mates.

Identification of the Queen Ant, Worker ants, Male or Drones.pdf
Queen ant
Today's article is about the head of ants, the "queen ant".
As we know, ants live in a highly organized and complex social system where three types of ants are found, viz.
1. The queen ant
2. Worker ants
3. Male or Drones
The queen ant is the only important member of the colony which lays eggs inside the colony and increases the population of the colony.New colony base:
New queens (who are the offspring of the eldest queen) within any existing colony come out of the colony at a certain time and look for a male for themselves. The sperm collects sperm inside your body in a sac-like structure called the spermatheca. After that, if she escapes from weather conditions or predators, she digs a suitable place on the ground and starts making her burrow, where she lays her eggs for the first time, from which only worker ants emerge after some time. Let's start the part work.
Determining the sex of the people of the colony:
This work is also done by the queen ant. If the sperms found inside it fertilize its eggs, then female ants (workers, new queens) come out of it and if the queen does not fertilize them then males or drones come out of it.
New queens are formed in the colony until the size of the colony increases to a certain extent before the queen ant releases chemicals from her body which are formed at the larval stage inside the female ants and ovaries. Stop being ...
Identification of the Queen Ant:
1. The queen ant is almost always larger than the other ants in the colony. However, its exact size depends on the species. For example, in leaf cutter ants, the queen is much larger than the worker ants, so it can be easily identified, while in carpenter ants, the worker ants are also quite large. The queen is a little difficult to identify.
2. At some point in the life of the queen ants, there must be wings that usually fall off after mating with the male and before forming a new colony. If you look closely at the queen, After the fall, you will see a bump on this place ... which is an important sign of her being a queen.
m
3. The queen ant is treated very differently in the colony, the rest of the ants are in charge of her care and take special care of her eggs and food. The queen ant is found in the very centre of the colony and around it. Soldier ants are present all the time. If you ever see a big ant and many small ants around it, it will likely be the queen ant.
The average age of the queen:
The average age of a queen can range from 2 to 30 years, depending on the type, diet and weather conditions.Several queen ants in a colony:
One or more queens can be found in a colony
A colony in which only one queen is found is called monogyny. There will be a girl ... It is very difficult for this colony to survive after the death of the queen.
A colony with more than one egg-laying queen is called Polygyny.
Remember that a monogyny colony can also have more than one queen, but we determine this by the number of queens lay
Unit-5 Agriculture Zoology.pptx
A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops.
Some animals are disliked because they bite or sting; snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mites, nematodes and gastropod molluscs. The damage they do results both from the direct injury they cause to the plants and from the indirect consequences of the fungal, bacterial or viral infections they transmit. Plants have their own defences against these attacks but these may be overwhelmed, especially in habitats where the plants are already stressed, or where the pests have been accidentally introduced and may have no natural enemies. The pests affecting trees are predominantly insects, and many of these have also been introduced inadvertently and lack natural enemies, and some have transmitted novel fungal diseases with devastating results.
Humans have traditionally performed pest control in agriculture and forestry by the use of pesticides; however, other methods exist such as mechanical control, and recently developed biological controls.Plants may be considered pests, for example, if they are invasive species or weeds. There is no universal definition of what makes a plant a pest. Some governments, such as that of Western Australia, permit their authorities to prescribe as a pest plant "any plant that, in the local government authority's opinion, is likely to adversely affect the environment of the district, the value of property in the district, or the health, comfort or convenience of the district's inhabitants."[12] An example of such a plant prescribed under this regulation is caltrop, Tribulus terrestris, which can cause poisoning in sheep and goats, but is mainly a nuisance around buildings, roadsides and recreation areas because of its uncomfortably sharp spiny burrs.Animals are considered pests or vermin when they injure people or damage crops, forestry, or buildings. Elephants are regarded as pests by the farmers whose crops they raid and trample. Mosquitoes and ticks are vectors that can transmit ailments but are also pests because of the distress caused by their bites. Grasshoppers are usually solitary herbivores of little economic importance. Many of the anima
Mimicry in insects
This document discusses different types of mimicry in insects. It begins by defining mimicry as when one insect resembles another to deceive predators. There are several types of mimicry discussed, including Batesian mimicry where harmless species mimic harmful ones, Mullerian mimicry where multiple poisonous species resemble each other, and aggressive mimicry where predators mimic prey. Specific examples are given such as bees, ants, and wasps mimicking each other's warning colors to deter predators. Self-mimicry, where body parts mimic other parts to confuse attackers, is also described.
Preposterous pet
Skunks are known for their ability to spray a liquid with a strong odor as a defense mechanism. They come in black and white or brown/cream colors as a warning. Skunks prey on honeybees by scratching their thick fur-protected paws at beehives and eating guard bees, a behavior mother skunks teach their young. They also eat human garbage, bird/rodent carcasses, pet food, grubs, and worms dug from lawns. Being omnivorous, skunks change their diets with the seasons to include insects, larvae, earthworms, grubs, small rodents, reptiles, amphibians, birds, moles, eggs,

You have persuaded XelPharms CIO that wireless networking would be.pdf
You have persuaded XelPharm\'s CIO that wireless networking would benefit many of the
company\'s employees. However, he requests that you plan the
network carefully and begin with a pilot network before migrating hundreds of clients to use
wireless technology. You decide to begin with a pilot network
in the distribution facility. The distribution facility is 200 feet long by 120 feet wide. It houses
45 employees during each shift, all on the same floor. What is
your first step in planning the pilot network? As part of your later planning, draw the network,
including the quantity and optimal placement of access points. What pitfalls, some unique to this
environment, are you careful to avoid? What wireless standard do you recommend and why?
Solution
There are many factors that need to consider before developing wireless network like cost,
bandwidth, use and devices that need to deploy in network following are some points that need
to consider for planning network
There are a number of reasons for a company to implement wireless networking. Wi-fi makes it
much easier for workers to connect to the LAN from their laptops in conference rooms, break
rooms, and other areas that may not have wired Ethernet jacks (or may not have enough for the
number of people present).
A wireless network also provides a way for you to allow visitors to access the Internet with their
laptops or handhelds (for example, to check their e-mail).Rolling out a wireless LAN within your
organization, however, is more complicated than just plugging in a wireless access point (WAP).
You need to address a number of factors in the planning stage to ensure both accessibility and
security.
Steps to pilot network:-
1) Establish a pilot that will test and confirm how wireless can work within your business
campus and needs.
2) Tie in Internet access and a robust data security system.
3) Install wireless access points, and equip notebook PCs for wireless use (e.g., provide PC cards
or upgrade to PCs with integrated wireless connectivity built in).
4) Train and turn your participants loose with their wireless notebook PCs. 5 After the pilot,
build on what you learn to broaden your wireless LAN (WLAN) to cover other areas and users.
Here are some of the things you should consider as you prepare to go wireless :-
The first step in planning your wi-fi deployment is to determine who will be using your wireless
network. This can affect network design. If the wireless network is primarily to give visitors
Internet access, you will want to isolate it from your wired LAN, perhaps by placing it in a
DMZ. If the wireless LAN is for the use of your workers, you will need to give them access to
resources on the wired corporate network without compromising the security of the main LAN.
If both outsiders and employees need wireless, you may want to establish two separate WLANs
to meet the needs of each.
The next step is to look at what type of traffic will flow over the WLAN. This analysis is
necessa.

1. The queen ant is almost always larger than the other ants in the colony. However, its exact size depends on the species. For example, in leaf cutter ants, the queen is much larger than the worker ants, so it can be easily identified, while in carpenter ants, the worker ants are also quite large. The queen is a little difficult to identify.
2. At some point in the life of the queen ants, there must be wings that usually fall off after mating with the male and before forming a new colony. If you look closely at the queen, After the fall, you will see a bump on this place ... which is an important sign of her being a queen.
m
3. The queen ant is treated very differently in the colony, the rest of the ants are in charge of her care and take special care of her eggs and food. The queen ant is found in the very centre of the colony and around it. Soldier ants are present all the time. If you ever see a big ant and many small ants around it, it will likely be the queen ant.
The average age of the queen:
The average age of a queen can range from 2 to 30 years, depending on the type, diet and weather conditions.Several queen ants in a colony:
One or more queens can be found in a colony
A colony in which only one queen is found is called monogyny. There will be a girl ... It is very difficult for this colony to survive after the death of the queen.
A colony with more than one egg-laying queen is called Polygyny.
Remember that a monogyny colony can also have more than one queen, but we determine this by the number of queens lay

A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops.
Some animals are disliked because they bite or sting; snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mites, nematodes and gastropod molluscs. The damage they do results both from the direct injury they cause to the plants and from the indirect consequences of the fungal, bacterial or viral infections they transmit. Plants have their own defences against these attacks but these may be overwhelmed, especially in habitats where the plants are already stressed, or where the pests have been accidentally introduced and may have no natural enemies. The pests affecting trees are predominantly insects, and many of these have also been introduced inadvertently and lack natural enemies, and some have transmitted novel fungal diseases with devastating results.
Humans have traditionally performed pest control in agriculture and forestry by the use of pesticides; however, other methods exist such as mechanical control, and recently developed biological controls.Plants may be considered pests, for example, if they are invasive species or weeds. There is no universal definition of what makes a plant a pest. Some governments, such as that of Western Australia, permit their authorities to prescribe as a pest plant "any plant that, in the local government authority's opinion, is likely to adversely affect the environment of the district, the value of property in the district, or the health, comfort or convenience of the district's inhabitants."[12] An example of such a plant prescribed under this regulation is caltrop, Tribulus terrestris, which can cause poisoning in sheep and goats, but is mainly a nuisance around buildings, roadsides and recreation areas because of its uncomfortably sharp spiny burrs.Animals are considered pests or vermin when they injure people or damage crops, forestry, or buildings. Elephants are regarded as pests by the farmers whose crops they raid and trample. Mosquitoes and ticks are vectors that can transmit ailments but are also pests because of the distress caused by their bites. Grasshoppers are usually solitary herbivores of little economic importance. Many of the anima
Mimicry in insects
This document discusses different types of mimicry in insects. It begins by defining mimicry as when one insect resembles another to deceive predators. There are several types of mimicry discussed, including Batesian mimicry where harmless species mimic harmful ones, Mullerian mimicry where multiple poisonous species resemble each other, and aggressive mimicry where predators mimic prey. Specific examples are given such as bees, ants, and wasps mimicking each other's warning colors to deter predators. Self-mimicry, where body parts mimic other parts to confuse attackers, is also described.
Preposterous pet
Skunks are known for their ability to spray a liquid with a strong odor as a defense mechanism. They come in black and white or brown/cream colors as a warning. Skunks prey on honeybees by scratching their thick fur-protected paws at beehives and eating guard bees, a behavior mother skunks teach their young. They also eat human garbage, bird/rodent carcasses, pet food, grubs, and worms dug from lawns. Being omnivorous, skunks change their diets with the seasons to include insects, larvae, earthworms, grubs, small rodents, reptiles, amphibians, birds, moles, eggs,

You have persuaded XelPharms CIO that wireless networking would be.pdf
You have persuaded XelPharm\'s CIO that wireless networking would benefit many of the
company\'s employees. However, he requests that you plan the
network carefully and begin with a pilot network before migrating hundreds of clients to use
wireless technology. You decide to begin with a pilot network
in the distribution facility. The distribution facility is 200 feet long by 120 feet wide. It houses
45 employees during each shift, all on the same floor. What is
your first step in planning the pilot network? As part of your later planning, draw the network,
including the quantity and optimal placement of access points. What pitfalls, some unique to this
environment, are you careful to avoid? What wireless standard do you recommend and why?
Solution
There are many factors that need to consider before developing wireless network like cost,
bandwidth, use and devices that need to deploy in network following are some points that need
to consider for planning network
There are a number of reasons for a company to implement wireless networking. Wi-fi makes it
much easier for workers to connect to the LAN from their laptops in conference rooms, break
rooms, and other areas that may not have wired Ethernet jacks (or may not have enough for the
number of people present).
A wireless network also provides a way for you to allow visitors to access the Internet with their
laptops or handhelds (for example, to check their e-mail).Rolling out a wireless LAN within your
organization, however, is more complicated than just plugging in a wireless access point (WAP).
You need to address a number of factors in the planning stage to ensure both accessibility and
security.
Steps to pilot network:-
1) Establish a pilot that will test and confirm how wireless can work within your business
campus and needs.
2) Tie in Internet access and a robust data security system.
3) Install wireless access points, and equip notebook PCs for wireless use (e.g., provide PC cards
or upgrade to PCs with integrated wireless connectivity built in).
4) Train and turn your participants loose with their wireless notebook PCs. 5 After the pilot,
build on what you learn to broaden your wireless LAN (WLAN) to cover other areas and users.
Here are some of the things you should consider as you prepare to go wireless :-
The first step in planning your wi-fi deployment is to determine who will be using your wireless
network. This can affect network design. If the wireless network is primarily to give visitors
Internet access, you will want to isolate it from your wired LAN, perhaps by placing it in a
DMZ. If the wireless LAN is for the use of your workers, you will need to give them access to
resources on the wired corporate network without compromising the security of the main LAN.
If both outsiders and employees need wireless, you may want to establish two separate WLANs
to meet the needs of each.
The next step is to look at what type of traffic will flow over the WLAN. This analysis is
necessa.

With the aid of an example, describe how RSVP works.
Solution
How RSVP Works
Basically,RSVP is based on signaling messages that traverse the network, allocating resources
along the way. RSVP is receiver-initiated, because sender initiation does not scale well to large,
multicast scenarios in which there are heterogeneous receivers. In multicast scenarios, the
application server sends out only one PATH message to multiple receiving computers, thus
conserving network bandwidth. In the case of multicast traffic flows, RESV messages from
multiple receivers are merged by taking the maximum values requested.
RSVP approaches to send data with best possible effort.
Following is the basic example how RSVP messages flow between a sender and receiver,
through the admission control host and intermediary hops.
Following steps involve in process of RSVP-
1. The multimedia server sends a PATH message requesting priority bandwidth to the
QoS ACS host . The message is ultimately headed to the receiver of the data. In the case of
multicast (multiple receivers), the PATH message is sent to the multicast address and received
by all hosts that are members of the multicast group. Note that it is RSVP messages that are
passed to the QoS ACS, not the data packets ultimately transmitted from sender to receiver.
Until confirmation of a reservation is received with a RESV message, data for the connection is
sent at a best-effort service level from the sending host. The best-effort service type instructs the
RSVP SP to use the application or service\'s QoS parameters as guidelines for service quality
requests, and makes reasonable effort to maintain the requested level of service. It does not make
any guarantees that requested QoS parameters are implemented or enforced.
2. If a QoS ACS server is present in the local subnet, the PATH message is routed via the
QoS ACS server. In this example, a QoS ACS host approves the request and forwards it to the
receiver (client). The PATH message travels through the network to the receiver, along the data
path determined by the network routing protocol.
3. A PATH state is maintained at each hop. Each PATH state contains a copy of the
PATH message and the IP address of the previous hop.
4. When a PATH message arrives at the intended receiver, the receiving host responds by
sending a RESV message that reserves the resources along the same network path traveled by the
PATH message.
Here, the receiver creates a RESV message, indicating that it wants to receive the data from the
multimedia server.

what causes hydrogen bonds to form between polar moleculesSolut.pdf
what causes hydrogen bonds to form between polar molecules?
Solution
Polar molecules are those, which dissociate in water and releases hydrogen (H+) or hydroxyl
ions (OH-). The partially charged opposite charges attract together, which results in hydrogen
bonding. For example, water molecules are held together by hydrogen bonding due to the
opposite partially polarity of hydrogen and hydroxyl ions..
What are the four main factors involved in the movement of ions acro.pdf
What are the four main factors involved in the movement of ions across the cell membrane in the
steady-state condition?
Solution
The four main factors are 1. Temperature ( increase in temperature makes membrane more
permeable) 2. pH ( membrane is more permeable in optimum pH) 3.membrane potential
(increase or decrease of the uptake of certain molecules or ions is dependent on membrane
potential. It increases with increasing potential) 4. Number of the channels present in the
membrane ( simply with the increase of number of channels more ions can pass through it).

The alpha-helix shown below is part of a water-soluble, globular prot.pdf
The alpha-helix shown below is part of a water-soluble, globular protein. Note that some amino
acids point \"toward\" you (Lys, Glu, Ser, Asp, etc.) and some point \"away\" from you (Phe, Ile,
Val, Ile, etc.). Which side of the helix (the side with the amino acids pointing \"toward\" you or
the side with the amino acids pointing \"away\" from you) would likely be the side of the helix
that is in contact with the cytoplasm (the watery fluid inside all cells), as opposed facing inward
toward the \"core\" of the protein?
Solution
Lys, Ser, Glu and Asp are hydrophilic amino acids whereas Phe, Ile, Val, Ile are hydrophobic
amino acids.
Hydrophilic amino acids seek contact with water whereas hydrophobic amino acids do not.
The hydrophilic amino acids tend to be on the outside of the protein molecules. Therefore the
hydrophilic amino acids would be in contact with the cytoplasm. The hydrophobic amino acids
would tend to orient towards the interior of the folded protein molecule..

in java Can we create an object of type Interface Explain your answ.pdf
in java Can we create an object of type Interface? Explain your answer.
Solution
No, we cannot create an instance of interface in java because interface contains only abstract
methods (ie. methods which are only declared) and as abstract methods do not have a body (of
implementation code), we cannot create an object of interface.
Though we can create instance of the class implementing the interface.
But we can refer to object that implements an interface.
example,
public interface Pet
{
}
public class Dog implements A
{
}
public static void main(String[] args)
{
Pet ob = new Dog();
//Pet test = new Pet(); // compilation error
}
Also,
Anonymous classes can implement interfaces, and it is the only time a class implementing an
interface without the
\"implements\" keyword.
It is possible to create Interface object with anonymous inner classes as shown below :
interface Sample {
public void display();
}
class Demo {
Sample p = new Sample() {
public void display() {
System.out.println(\"Interfce example.\");
}
};

Genetics homework
1. The rut site involved in Rho-dependent termination is what type of molecule?
DNA
RNA
Protein
Two of the above.
All of the above.
2. Life forms on a newly discovered exo-planet (planet found outside of our solar system) are
very similar to those found on Earth, except their proteins are made of 128 different amino acids.
Otherwise, their DNA and RNA compositions are identical to those found on Earth. This
observation suggests that the codons coding for the amino acids are likely to be at least how
many bases long?

6A.
DNAB.
RNAC.
ProteinD.
Two of the above.E.
All of the above.
Solution
1) the answer is RNA - SsRNA.. It is a protein which is involved in the termination of
transcription.!! It acts on the SsRNA after the open reading frame where there is G/C less
sequence..!!
2) the answer is 4.. As 4^ 3 = 64 codes for 20 amino acids so we can say that there is
degeneracy.. If there is 64 codons it will code for only 64 amino acids for outer organism. But
there are 128 amino acids given Similarly, 4^4= 256 which can code for 128 a.a including
degeneracy as it is closest of no of amino acids.

Cuckoos are birds that practice brood parasitism. Instead of raising.pdf
- 1. Cuckoos are birds that practice brood parasitism. Instead of raising her own young, a mother cuckoo finds another bird’s nest and lays her egg when the other is away. The other bird dutifully cares for the cuckoo egg until it hatches. The cuckoo hatchling, before it can even see, senses the touch of other eggs in the nest and ejects them by pushing against them with its body. Characterize the hatchling’s behavior, using Tinbergen’s first two questions for understanding a behavior. What is the stimulus for the behavior? What is the response? How does prior experience influence the behavior? Solution The cuckoo is the best known brood parasite an expert in the art of cruel deception. Its strategy involves stealth, surprise and speed. Cuckoos will not build their own nest. Female cuckoos will find another bird’s nest and in the absence of the parent she removes one of the original egg and removing it from nest laying her own egg. Cuckoos parasitize the nests of a large variety of bird species and carefully mimic the colour and pattern of their own eggs to match that of their hosts. To give proper parental care to their egg. The bright red mouth act as stimulus to the foster parent to feed it regularly. It carefully mimic the colour and pattern of their own egg to match with the hosts.
