Describe a similarity transformation that maps trapezoid WXYZ to trapezoid PORS. Give the
scale factor and name the type of dilation in your description. Similarity transformation: Type of
dilation: Scale factor: Ay 4 6 4
Solution
Since WXYZ maps to PQRS.
Since PQRS is twice of WXYZ and reverse of it.
Hence scale factor = -2
Type of dilation is enlargement because a dilation that creates a larger image is called an
enlargement.

Which of the following is NOT a rationale for using mRNA intermediates in gene expression? to preserve its original, pristine copy of the gene DNA lacks the necessary information for protein production. to amplify the response to its changing needs to connect the information (DNA) with protein-producing organelles (ribosomes) Solution Answer b) DNA lacks the necessary information for protein production. Reason - This is not true because DNA contains all the necessary information required to code all the proteins. the same information is being transcribed on mRNA molecule during transcription process and the same information is translated into an amino acid sequence from mRNA into protein. in fact, DNA contains all the necessary information for protein production..

This problem is based on the \"B92\" method of quantum key distribution. See Physics World. May 1999. Photons are directed at a polaroid sheet held by Alice. The Transmission Axis (TA) of Alice\'s sheet is either vertical (V) or at 45degree. When Alice wants to send a \"1\" bit she uses the 45degree orientation and when she wants to send a \"0\" bit she uses the V orientation. Some distance away Bob has two polaroid sheets. His polaroid TA can be either horizontal (H) or at -45degree. When Bob uses his H sheet he assigns a \"1\" bit to any photon he observes. When Bob uses his -45degree sheet he assigns a \"0\" bit to any photon he observes. For each of the two types of photons that Alice can send make a table showing what Bob sees with each of his two polaroid orientations. For each case give the probability that Bob sees a photon. Bob and Alice keep the bits for which Bob saw a photon and they use these as the key. In this method they never discuss the polaroid orientations but just note the cases where Bob observed a photon. Show that for the kept subset of bits Bob and Alice agree on the bit values. Alice and Bob choose their polaroid sheets at random. What fraction of bits sent by Alice will be seen by Bob and therefore used? What happens if an evesdropper Eve, places a polaroid sheet (for example in the H direction) between Alice and Bob. What fraction of photons will Alice and Bob agree on now? Solution If Alice and Bob use the sheets at random, Bob would see 50% of bits sent by Alice on an average. if a polaroid with H direction is placed in between Alice and Bob, he would see a photon always. The phtons coming out of the intermdiate would be alinged along H, which can be consdiered as composed of +45 and -45. Thus Bob will always see a photon, whether he uses H sheet or -45 sheet.AliceAliceBobBobBob.Porb.V0H000-4511+451H111-4500.

The main difference between passive and active transport is the specificity of the target molecule involved. the requirement for ATP. various gradient and osmotic pressures within the cell. the ability to maintain voltage across the membrane. diffusion versus membrane protein mediated transport. Co-transport occurs when active transport of a solute indirectly drives transport of another solute. 2 ions are transported in opposite directions across the membrane. a proton pump makes ATP. the voltage across the membrane suddenly changes. only during photosynthesis in plants. Match the following terms Phagocytosis Cell pooping. (_____) Pinocytosis Ingesting big particles. (_____) Exocytosis Cell sipping. (_____) Solution Answers : Question number 6 : The correct answer is B ( The requirement of ATP) Explanation : Passive transport is a type of transport in which ions or molecule move across a membrane down the concentration gradient. It doesnot uses any metabolic energy for this purpose. There are three types of passive transport which includes osmosis, simple diffusion and facilitated diffusion. In contrast to passive transport, active transport uses metabolic energy such as ATP to move an ion or a molecule against their concentration gradient (from a region of lower concentration to regions of higher concentration). Example of active transporter : Na+ K+ ATPase pump..

So I don\'t understand explicit equations. Whats the formula and how are they different than recursive? Solution in explicit formula we just need to know the term number to find any term of the sequence whereas in recursive formula each term is defined by its preceding term.so to find any term of the sequence we must know the preceding term lets understand by an example let a sequence be 1, 4 , 7 , 10 ... a1 = 1 , difference between 2 terms = 3 for explicit formula an = a1 + (n-1)*3 we just need to plug the value of n to get any term of the sequence for recursive formula an+1 = an + 3 to get any term of the sequence we need to know the preceding term for eaxample to find a3 we plug n = 2 a2+1 = a2 + 3 a3 = a2+ 3 tehrefore we need to know a2 term to get a3 term.

Sapling Learning Select the statements that explain why duplication is a driving force for evolution and the generation of genes. variations can occur when random fixed mutations are introduced into a new chromosomal Duplication of a gene segment always results in novel phenotypes. Duplicated genes provide extra copies of DNA that are not constrained by an essential function. Genes duplicate then diverge from the original sequence to create novel genes and Solution Statement No. 1, 3 and 4 justify the fact that Gene duplication driving force behind Evolution. 1) Occurence of fixed mutation in new genotypic environment result may result into deletion of another gene function or enhancement of gene responsible for a particular phenotype. this enhancement (example curvature of spine and straightening of posture) or deletion (example disappearance of tail) can be beneficial to the organism and is passed to future generations thus leading to evolution of new species. 2) Duplicate copies of DNA, after a period of time, are often rendered redundant and are no longer constrained by any essential function. These redundant copies often result in acquiring new function and lead to evolution. 3) Gene duplication, followed by their divergence leads to formation of novel genes and take part in evolution. 4) Novel gene generation result may from interaction between two different genes. However, it is not always that duplication of a gene will always result in new phenotypes. Thus, Statement 1,3 and 4 are true to the statement that gene duplication result into evolution and generation of new genes..

Question 1 Humans have affected different organism populations in which of the following ways? (Select all that apply) overfishing agriculture poaching habitat destruction An explanation supported by a large body of observations and experimentation is referred to as a(n): hypothesis. investigation. prediction. supposition. theory. Interactions between organisms lead to the evolution of particular traits in populations of those organisms over time. False True Mutations always result in death of the organism that acquires them. False True Variation among individuals in a species is usually caused by: environmental variation. Solution 1. Human activities, in its extreme form have adversely affected different population of organisms. The important activities that contributed to the negative impacts include overfishing, poaching, agriculture, and habitat destruction. Overfishing happens when large volumes of fish are caught than its population is capable of replacing through natural reproduction. This activity adversely affects the balance of life in the oceans and also the social and economic well-being of the coastal communities\' dependant on fishing as their livelihood. Eg: The population of Atlantic bluefin tuna has declined and is facing near extinction. Targeted fishing of predators, such as tuna and groupers, led to over population of smaller marine species, such as sardines and anchovies, thus changing the marine ecosystem. The State of World Fisheries and Aquaculture (SOFIA) by United Nations has published a two yearly report in 2006 giving the statistical data on the effects of overfishing. Poaching is the activity of illegal or unauthorized hunting of a specific animal species for sport or profit. The excessive and unregulated hunting of African elephants for their tusk has lead to the drastic reduction in their population. The poaching of wolves, which is the natural predator of elk, lead to an unsustainable population level of the later resulting in scarcity of food sources and their mass extinction. The unsustainable agricultural practices pose the greatest instant threat to species and ecosystems around the world. The adverse environmental impacts include habitat loss of species (due to land conversion), environment pollution, soil erosion, climate change and genetic erosion. Habitat destruction occurs when irreversible change has happened to an area that is incapable of supporting the natural wildlife. This change can be destruction, fragmentation, or degradation. Eg: Clearing a wooded area using bull dozer, filling of wetlands, construction of roads and dams etc..

Problem 4. The ancient Romans employed a volcanic ash called pozzolana to make a material somewhat similar to the modern Portland cement concrete. Consult sources bevond the textbook and write two or three paragraphs about how this material differed from modern concrete, and how it was similar, and the Roman\'s degree of success in using it as a building material Solution solution A pozzolanic material is essentially a silicious or aluminous material which in itself possess no cementitious properties, which in finely divided form and in the presence of water reacts with calcium hydroxide, liberated in the hydration process at ordinary temperature to produce compounds possessing cementitious properties. This is differed from modern concrete as pozzola portland cement produces less heat of hydration and offers great resistance to the attack of impurities in water than OPC. It evolves less heat and its initial strength is less but final strength is equal to OPC.It has lower rate of development of strength than OPC.

Plants and Chromatography Separation of Photosynthetic Pigments by Paper Chromatography Paper Chromatography and Leaf Pigments Why do some pigments move further than the others? (What happens if the solvent is rubbing alchohol?) Solution Answer: The speed at which a particular pigment moves depends on its relative affinities for the two solvent phases-Mobile phase (solvent) and stationary phase (water) If the pigment has no affinity whatever for the water phase, it will travel at maximum speed. On the other hand, if the pigment has no affinity whatever for the non-polar phase, it will remain stuck at the origin of application..

1)Why have concerns over pollution become so important for management and directors? 2)How can corporations ensure that their employees behave ethically? Solution 1) Stakeholders increasingly expect that a company\'s activities are in the best interest of the society and the people. Stakeholders want their companies to work not just to increase their wealth but also their standard of living by keeping the pollution to a level which is well below the environmental guidelines and which is not harmful to the people (ie: responsible for smog, polluted water, acid rain). Also, now it has become the corporate social responsibilty to keep the pollution level well below the guidelines and rules. This helps to increase the goodwill of the company which in turn increase the faith of investors in the company. 2) Corporations can ensure the same by taking various steps and incentives. Following are certain ways by which corporations can esure the same:- There should be a proper code of conduct within the company which says that employees should behave in a certain way. Employees must be motivated and trained and be given incentives to work hard in the interests of stockholders. Their behavior must be observed to ensure they do not behave illegally or unethically that threaten the trust of stockholders and public in the compny. In many companies employees focus on maximizing their own wealth. In an effort to prevent scandals the Securities and Exchange Commission (SEC), continues to increase regulations that increase transparencies and eliminate conflicts of interest. The SEC’s goal after each major crisis is to prevent the unethical behavior and illegal behavior. Corporations can ensure that their employees behave ethically by creating segregation of duties where appropriate, creating an incentive program that doesn’t encourage unethical behavior, having control systems in place, a proper hiring process, and athorough training process. There should be proper system in place to ensure that such unethical behaviour will be caught. Corporations need to ensure that their employees understand their responsibilities in carrying out their duties and responsibilities..
