There are two large plants in the authors’ yard: a yucca tree and an enormous prickly pear cactus. Both have rough, scaly bark, but it is known that these plants are not closely related. (a) What are two different explanations for the similarity of the bark? (b) It is also known that yuccas are descended from a grass species instead of a tree species. Which of the two explanations given in part a is consistent with this fact? Solution A) Two different explanations for the similarity in bark i) yucca plants adapt to the environment that they live in. Depending on the type of environment, the yucca plants develop fleshy thick leaves for deserts. They also adapt to the mountains, coastal sands, grasslands and prairies. ii) there are some yuccas which are also common to the southwest desert scene. They have similar characteristics like the traditional cactus. There is a high chance that the yucca present in the author\'s yard is a desert origin yucca, thus a similarity in the bark. Yucca filamentosa , which is the grass species of yucca is more found in the desert environment than the other species of yucca. The second explanation for the similarity in bark is more consistent in this case with the variation in species ..

The seaport town of New Monopoly has become extremely popular with shipping companies due to its superior location. The port has become so congested that ships must wait hours every day just to dock. This is an example of The major of New Monopoly realizes that the congestion at the port costs the shipping companies and its town money. Which decision would NOT move him towards a command economy? Solution ans 1 b) private good as por is congested so it is rival and exclusive in use that\'s why port is private good ans 2 b) The mayor decides to let individual firms and consumers find a solution for the excessive wait time. this decision would not move him towards a command economy because this means giving individual firms and consumers power to decide about solution themselves which means mayor is not using his dominating power of command economy.

report “Rabbits and Wolves”Discuss the changes in parameters and how they affected the population growth curves for each organism (be sure to mention particular changes in the graphs and ending populations). Think about how this simulation could apply to the real world. What other factors or variables would have to be included. What if humans were added as a fourth organism, how would they affect this simulation? Also, do you think that a computer model is a useful tool to science? More precisely do you think there are times when such a model is useful and when such a model is not useful? Be sure to start your discussion with a statement of objectives - I have listed objectives above, write and state if you think you obtained the objectives and explain why or why not. There is absolutely no penalty for thinking that you didn\'t complete one of the objectives. Solution Ans.) To understand the different models that are used to represent population dynamics, first understand the general equation for the population growth rate (it is the change in number of individuals in a population over time): dT/dN=rN In this equation, T = growth rate of the population NNN = population size TTT = time rrr = per capita rate of increase (that is, how quickly the population grows per individual already in the population). The equation above is very general, and we can make more specific forms of it to describe two different kinds of growth models: exponential and logistic. A positive growth rate implies that the population is increasing, whereas a negative growth rate shows that the population is reducing. A growth ratio of zero indicates that there is a balance i.e. that there were the same number of organisms at the beginning and end of the particular time period. Sometimes, growth rate may be zero even when there are significant changes in the birth rates, death rates, immigration rates and age distribution between the two times period. Situation which includes exponential development, different age-independent density variable influencing survival, three influencing fertility. The one function meeting the presumptions of the calculated model delivered a strategic development bend typifying the right values or rm and K. The others created sigmoid bends to which self-assertive strategic bends could be fitted with differing achievement. In view of population time slacks, two of the capacities influencing fruitfulness created overshoots and damped motions amid the underlying way to deal with the enduring state. The other factors or variables would have been included in the given situation would be the climate condition. In my opinion computer model is a useful and informative tool in analyzing the population growth curves of any organism. In most of the cases, the computer model for population growth studies is logical..

Communications satellites are used for television, telephone, radio, internet, and military applications. There are over 2,000 communications satellites in Earth’s orbit, used by both private and government organizationsWireless communication uses electromagnetic waves to carry signals. These waves require line-of-sight, and are thus obstructed by the curvature of the Earth. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated points.[2] Communications satellites use .

First, describe what a force is and what effects forces have on objects. Provide one or two examples of forces operating at a macroscopic scale to help you form analogies to describe atomic phenomena. Then describe the forces involved in holding matter together at the atomic level. Describe what would happen if various atomic forces disappeared? Also, provide a description of some of the forces between atoms that result in molecules and larger collections of atoms, and how these forces are important Solution Force changes the state of motion and state of rest , Force is a push or pull which creats acceleration , forces changes direction of the objects moving . force change shape of the objects, force is the capacity to do work. Forces work at the macroscopic level prmarly is gravity which is responsible for the whole mass in the universe to stay in tact with out getting fly away , the same gravity makes stars , solar systems and helps the formation of planets. The fource basic forces of nature are , Gravity , Electromagnetic , strong nuclear forces and weak nuclear forces, out of which gravitational forces works at macroscopic scale and rest of the threee works in microscopic scale on matter. Electromagnetic force is responsible for holding all the atoms in molecules to gether ,and also the same force behind all the chemical reactions. the stong nuclear and weak nuclear forces are the backbone behind the binding of nucleons in nucleus. Strong and weak nuclear force play key role in the formation of heavy nucleus from individual protons, electromagnetic forces are responsible for the formation of atoms , with out either stong nuclear and EM force atoms may not exist in our universe , and gravity plays the leed role for the formation of stars where the systhesis of all the nucleus takes places, with out gravity the universe may left with individual protons and electrons . The residual attractive or repulsive forces between atoms, molecules, and surfaces, as well as other intermolecular forces are called vander waals forces, which arise due to electromagnetic fields, van der Waals forces are weaker than normal covalent ionic bonds which are short-range forces and should be considered only if the molecules are closer , these forces are important in the formation of macrosizd molecules in the formation fo liquids and protein stuctures and DNA..

Discuss the role of proteins in membrane structure and transport of molecules across the membrane? (AP Biology II Free Response Question) Solution These three macromolecules together to form a complex phospholipid bilayer in which periplasmic proteins are distributed in a mosaic manner. The large fluid mosaic structure is formed from these macromolecules composed of phospholipid bilayers with protein channels for the transport of organic & inorganic nutrients including trace metal. Normally, the essential aspects of these structures composed of \"porins, protein channels, integral proteins” that dictate their function for the selective permeability, diffusion of nutrients across the membrane into & out of the cell finally to attain homeostasis Membrane phospholipids are the molecules with hydrophillic polar heads towards the solvent such as water whereas hydrophobic tail located towards the center of the layer and this bilayer formed by micelles, as fatty acids possess one polar associated with another nonpolar head. Biological lipid bilayers are composed of phospholipids to form spontaneously into bilayers because the hydrophobic tails, which associate as \"amphiphilic phospholipids\" with hydrophilic phosphate head. Cell membrane possesses a property known as selective permeability. Cell membrane consists of phopholipid bilayer that also include several of the transmembrane proteins, ion channels etc. Small, non-polar molecules with hydrophobic nature diffuse more easily into the cell membrane. Similarly, proteins interact and assemble themselves to form several layers of structures in our body. Small particles are such as oxygen and CO2, urea can cross the lipid bilayer easily through diffusion compared to glucose (channel mediated-sodium dependent transport into the cell), amino acids (channel mediated) and various ions etc. Atoms that can form hydrogen bonding or electrostatic interactions arranged in complementary fashion to create a hydrophobic pore. Within the cell membrane, the tail portions (lipid region) bonded together and the head portions (hydrophilic region) exposed into cell interior and exterior, which is very essential for the selective permeability of cell membrane. Membrane proteins can contain several transmembrane elements for example G-protein coupled receptors contain 7-transmembrane regions with helical protein subunits. These membrane proteins can occupy only one side of the membrane but majority to the internal surface & some of these proteins are in the membrane are locked into the membrane for ligand binding via other cross-linking membrane proteins or by polar phospholipid heads with ionic interactions. Majority of transmembrane poritens are three dimentional with \"alpha-helical sheets\" in their structure These proteins of mosaic model possess significant characteristics in pertinent to a lot of cellular processes such as cell-cell signaling, cellular apoptosis followed by cell death, membrane budding, and biol.

CASE STUDY: There is a new phenomenon in the cybersecurity domain called: “Bring Your Own Device (BYOD)” where employees can bring their personal devices at work and connect using the Wi-Fi to the organization’s network. Many employers are allowing their employees to use their personal mobile device for enterprise functions such as corporate email, work applications, etc. While this may save the company costs, the organization’s network remains vulnerable. A company can only monitor so much that’s on an employee personal device; Assess the threats, the vulnerabilities, and the impacts on an organization’s information systems posed by the use of mobile devices at work. What can be done to fix it at the policy level, technology level, and infrastructure level? Solution Employees aren\'t just bringing their mobile devices to the workplace — they\'re living on them. A 2015 study by Bank of America found that 55 percent of respondents sleep with their smartphones on their nightstands to avoid missing a call, text message or other update during the night. The devices are also the first thing on their minds in the morning: while 10 percent reported thinking of their significant other, 35 percent reserved their first thought of the day for their smartphone. As smartphones and tablets become constant companions, cyber attackers are using every avenue available to break into them. Many people expect that iPhone or Android devices are secure by default, when in reality it is up to the user to make security configuration changes. With the right (inexpensive) equipment, hackers can gain access to a nearby mobile device in less than 30 seconds and either mirror the device and see everything on it, or install malware that will enable them to siphon data from it at their leisure. The nature and types of cyber attacks are evolving rapidly, and mobile devices have become a critical part of enterprise cyber-security efforts with good reason. Analysts predict that by 2018, 25 percent of corporate data will completely bypass perimeter security and flow directly from mobile devices to the cloud. Chief information security officers (CISOs) and other security executives are finding that the proliferation of mobile devices and cloud services present a significant barrier to effective breach response. In order to secure the corporate data passing through or residing on mobile devices, it is imperative to fully understand the issues they present. 5 Security Risks and a Surprising Challenge The threat and attack vectors for mobile devices are largely composed of retargeted versions of attacks aimed at other endpoint devices. These risks can be categorized into five areas. 1. Physical access Mobile devices are small, easily portable and extremely lightweight. While their diminutive size makes them ideal travel companions, it also makes them easy to steal or leave behind in airports, airplanes or taxicabs. As with more traditional devices, physical access to a mobile devi.
