There was a mass extinction of plants and animals at the end of the Permian period 250 million years ago. Which of the following would be a reasonable prediction for the fungal fossil record? A. There should be a massive increase in saprophytic fossils during the extinction, and then a massive decline shortly after the extinction was complete. B. There should be a massive increase in mycorrhizal fossils during the extinction and few afterward. C. There should be a massive decrease in all fungal fossils just prior to the time that plant and animal species started to decline, and the number of these fossils should remain low throughout the extinction period. D. There should be a slow increase in all fungal fossils during the time that plant and animal species declined, with their numbers staying relatively high after ward since there was little competition from other species. Solution correct answer:-(A)There should be a massive increase in saprophytic fossils during the extiction,and then a massive decline shortly after the extiction was complete. Because when the saprophytic plants died,they must have definitely become a large amount of fossil.Moreover fungal fossils are very difficult to identify,only except some fungi.When the extinction was complete it was shortly decline..

In line with generally accepted theories of evolution, Dinosaur extinction is currently believed to be due to climate change due to various causes. However this is not correct, being inconsistent with known facts. There are only two possibilities. Either Dinosaurs evolved to their extinction or evolved to some other phyletic lines or species with which ancestor – descendent relationship can’t be presently demonstrated. Author: Dr Mahesh C. Jain is a practicing medical doctor and has written the book “Encounter of Science with Philosophy – A synthetic view”. The book begins with first chapter devoted to scientifically valid concept of God and then explains cosmic phenomena right from origin of nature and universe up to origin of life and evolution of man. The book includes several chapters devoted to auxiliary concepts and social sciences as corollaries to the concept of God. This is the only book which deals with origin of nature and universe from null or Zero or nothing. Chapter 30 of the book is about Evolution of Life wherein author has worked out a new theory about evolution of life. Visit:http:// www.sciencengod.com http://www.sciencengod.com/clipboard.htm

Review and Thought Questions for Natural History and Physiological Ecology 1) The oldest vertebrates originated in aquatic habitats, but mammals arose in more recent time in terrestrial habitats. However, some mammalian species have since evolved life history strategies for living in aquatic habitats (beavers, sea otters, mink, whales, dolphins, etc). What physiological problems do aquatic mammals face? What causes these problems? If there are so many physiological issues, what are the benefits for aquatic mammals, specifically for aquatic mammalian a) carnivores and b) herbivores? 2) A)The species composition of boreal forests and tundra are much more similar than the species composition of tropical rain forests and Mediterranean woodlands around the globe. What causes this? What are the management implications? B) Sasquatch are only found in the boreal forest of northern Canada. The exceptions are some smaller, isolated populations at high elevation in southern Colorado, over 2,000 miles away. Explain how this distribution pattern is possible. 3) One species of aquatic plant lives at the edge of wetland habitats in very shallow water that occasionally dries, while another species is found only in deep-water habitats that never dry. A) which species likely has a wider "physiological tolerance" for abiotic factors (said another way, a larger fundamental niche). B) abiotic factors in the deeper habitat are within the tolerance range of the shallow water species, why isn't the shallow species found in high numbers in the deeper-water habitat? Use natural selection to argue why you usually wouldn't expect species to have exactly the same physiological tolerances or exactly the same distribution. C) which species likely has a larger geographic range? Why? D) which species is probably a better overall competitor? Why? 4) An underlying theme of physiological ecology is adaptation of organisms to their local environments. But these adaptations shouldn't be viewed as an optimal fit of species to their environment. In fact, over geological time, nearly all species have gone extinct. Discuss why this is the case. Why cant natural selection "prevent" species extinctions? 5) Use optimal foraging theory to explain the widespread love of fatty foods in humans. 6) In your own words, explain the relevance of the saying "a jack of all trades is a master of none" to the field of ecology. .

Between 2000 and 2002, then again from 2008 to 2010, access measures showed no improvement and quality of care measures improved more slowly in racial groups and certain ethnic populations, than the improvements for the total population. Solution Ans: The health care quality chasm is better described as a gulf for certain segments of the population, such as racial and ethnic minority groups, given the gap between actual care received and ideal or best care quality. The landmark Institute of Medicine report Crossing the Quality Chasm: A New Health System for the 21st Century challenges all health care organizations to pursue six major aims of health care improvement: safety, timeliness, effectiveness, efficiency, equity, and patient-centeredness. “Equity” aims to ensure that quality care is available to all and that the quality of care provided does not differ by race, ethnicity, or other personal characteristics unrelated to a patient\'s reason for seeking care. Baylor Health Care System is in the unique position of being able to examine the current state of equity in a typical health care delivery system and to lead the way in health equity research. Its organizational vision, “culture of quality,” and involved leadership bode well for achieving equitable best care. However, inequities in access, use, and outcomes of health care must be scrutinized; the moral, ethical, and economic issues they raise and the critical injustice they create must be remedied if this goal is to be achieved. Eliminating any observed inequities in health care must be synergistically integrated with quality improvement. Quality performance indicators currently collected and evaluated indicate that Baylor Health Care System often performs better than the national average. However, there are significant variations in care by age, gender, race/ethnicity, and socioeconomic status that indicate the many remaining challenges in achieving “best care” for all. Explanation: The U.S. health care system is designed to improve the physical and mental well- being of all Americans by preventing, diagnosing, and treating illness and by supporting optimal function. Across the lifespan, health care helps people stay healthy, recover from illness, live with chronic disease or disability, and cope with death and dying. Quality health care delivers these services in ways that are safe, timely, patient centered, efficient, and equitable. Unfortunately, Americans too often do not receive care they need, or they receive care that causes harm. Care can be delivered too late or without full consideration of a patient\'s preferences and values. Many times, our system of health care distributes services inefficiently and unevenly across populations. Some Americans receive worse care than others. These disparities may occur for a variety of reasons, including differences in access to care, social determinants, provider biases, poor provider-patient communication, and poor health literacy. Each.

Below is a diagram of the coding strand of DNA showing a gene please use this image for questions 3 and 4). The arrow represents the transcription start site. Which region contains the 3\' Untranslated Region (UTR)? A B C D E Solution Answer: D Reason: When transcription occurs, the m RNA formed is longer than the actual RNA code for protein . It has few bases at 5’ and 3’ end to protect its degradation in cell environment. While translation, which started at middle of exon 1 and stopped at the middle of exon 3, Exon 1 has few portion (C), and exon 3 has few portion (D), which is not undergoing translation. These regions are known as translated regions at 5’ (C) and 3’ (D) end respectively. DNA has 5’ (in diagram) and 3’ (opposite end, not shown in diagram)..

A patient has a tidal volume of 0.50 L, a frequency of breathing or respiratory rate of 19.0 breaths/min, and an anatomical dead space volume of 0.20 L. Calculate the alveolar ventilation rate. Solution The alveolar ventilation (VA) and the dead space ventilation/volume (VD) together combine to form pulmonary ventilation rate (V). So, V = VA + VD or VA = V - VD The pulmonary ventilation rate is given by, V = VT x f Where VT = Tidal volume and f = Respiratory Rate Here we know, VT = 0.5 and f = 19. So, V = 0.5*19 = 9.5 L We are given that VD = 0.2 L, So, VA = 9.5 - 0.2 = 9.3 L Hence, VA i.e. Alveolar Ventilation rate is 9.3 L/min.

Why having a lipid rich cell wall make a bacteria harder to stain? Solution In lipid rich cell walled bacteria the alcohol easily pass through the walls making loss of lipid and increasing pores in the membrane thus making the cell wall more porous and the stain is easily washed out distaining the cell. So it is difficult to retain the stain inside the lipid rich cell walled bacteria while staining (Harder to stain)..

The fundamental theory of electromagnetic field is based on Maxwell\'s equations. These equations govern the electromagnetic fields, E, D, H, and there relations to the source, f and p_v. In a source-free region, list the Maxwell\'s equations for time-harmonic fields: Given the Phaser from of the electric field E? For the above given electric field, is B varying with time? Why? Solution Maxwell’s equations simplify considerably in the case of harmonic time dependence. Through the inverse Fourier transform, general solutions of Maxwell’s equation can be built as linear combinations of single-frequency solutions:† E(r, t)= E(r, )ejt d2 (1) Thus, we assume that all fields have a time dependence ejt: E(r, t)= E(r)ejt, H(r, t)= H(r)ejt where the phasor amplitudes E(r), H(r) are complex-valued. Replacing time derivatives by t j, we may rewrite Eq. in the form: × E = jB × H = J + jD · D = · B = 0 (Maxwell’s equations) (2) In this book, we will consider the solutions of Eqs. (.2) in three different contexts: (a) uniform plane waves propagating in dielectrics, conductors, and birefringent media, (b) guided waves propagating in hollow waveguides, transmission lines, and optical fibers, and (c) propagating waves generated by antennas and apertures Next, we review some conventions regarding phasors and time averages. A realvalued sinusoid has the complex phasor representation: A(t)= |A| cos(t + ) A(t)= Aejt (3) where A = |A|ej. Thus, we have A(t)= Re A(t) = Re Aejt . The time averages of the quantities A(t) and A(t) over one period T = 2/ are zero. The time average of the product of two harmonic quantities A(t)= Re Aejt and B(t)= Re Bejt with phasors A, B is given by A(t)B(t) = 1T T0 A(t)B(t) dt = 12 Re AB] (4) In particular, the mean-square value is given by: A2(t) = 1T T0 A2(t) dt = 12 Re AA]= 12|A|2 (5) Some interesting time averages in electromagnetic wave problems are the time averages of the energy density, the Poynting vector (energy flux), and the ohmic power losses per unit volume. Using the definition) and the result (.4), we have for these time averages: w = 1 2 Re 12E · E + 12H · H (energy density) P = 1/ 2 Re E × H (Poynting vector) dPloss dV = 1/ 2 Re Jtot · E (ohmic losses) (6) where Jtot = J + jD is the total current in the right-hand side of Amp`ere’s law and accounts for both conducting and dielectric losses. The time-averaged version of Poynting’s theorem is discussed in Problem 1.5. The expression (1.9.6) for the energy density w was derived under the assumption that both and were constants independent of frequency. In a dispersive medium, , become functions of frequency. In frequency bands where (), () are essentially real-valued, that is, where the medium is lossless,that the timeaveraged energy density generalizes to: w = 1/ 2 Re 1/2 d() d E · E + 1/2 d() d H · H (lossless case) (.7) The derivation of (.7) is as follows. Starting with Maxwell’s equations (1.1.1) and without assuming any particular constitutive relations, we obtain:.

Part I – Antibiotics and the Human Microbiome Amelia and her family had just returned from a family vacation in Mexico. While there they had enjoyed an abundance of fresh fruit and vegetables from the local street vendors outside of their hotel. Amelia’s mother normally would have avoided these fruit stands because her doctor had warned her to be cautious of raw produce while travelling in less developed countries. But she recently had read a New York Times article illustrating the benefits of various microbes on the immune system and decided to embrace the local agriculture in Mexico as a result. However, by the end of their trip, they all had begun to suffer from nausea and diarrhea. Their family doctor diagnosed 16 year-old Amelia and her family with food poisoning and promptly placed them all on antibiotics. While her brother and parents started feeling better relatively quickly, Amelia continued to suffer from gastrointestinal (GI) distress. She found that she couldn’t leave her home because she was constantly running to the bathroom (10–12 times per day). While the rest of her family seemed well rested and recovered, Amelia felt tired, had severe abdominal cramping, and had lost her appetite. After visiting a gastroenterologist, Amelia was diagnosed with Crohn’s disease (CD). CD is a chronic inflammatory bowel disease, where the immune cells in the intestine become overly sensitive to the bacteria residing in the intestines causing pathologic inflammation in the lining of the GI tract. It typically presents in the small intestine but can occur anywhere along the GI tract from the mouth down to the anus. Determined to shed some light on her diagnosis, Amelia began to search the Internet for information. As she read many personal stories of other Crohn’s patients, she noticed many of them also had the first onset of their disease following a course of antibiotics. She was astonished to find that her intestines were the home for billions of bacteria collectively called the gut microbiota. In fact, she read that there were more than 10 times the number of bacterial cells in her body than human cells; best estimates suggested there are 1013 bacterial cells in a single human body. She was also surprised to discover that some scientists estimate as many as 10,000 different microbial species reside in or on the average healthy human body (Proctor, 2012). She found an article in Wired (http://www. wired.com/2011/09/mf_microbiome/) that described the impact of antibiotics on the gut microbiota. Amelia was particularly struck by the figure that illustrated the lasting impact that antibiotics have on microbial diversity in the intestines. She began to wonder about the impact her recent course of antibiotics had had on her intestines and what it meant for her health. Questions 1.Look at the figure that Amelia found in Wired pertaining to antibiotics and the microbiota. What conclusions can you draw from this figure? 2. Given the fact that Amelia fou.

Since somathesthetic sensation from each side of the body projects to the contralateral postcentral gyrus _______ must have occurred at some point along the pathway. Solution Answer: Since somathesthetic sensation from each side of the body projects to the contralateral postcentral gyrus _ decussation_ must have occurred at some point along the pathway. Reason: Somatosensory system- decussation: Proprioceptors (receptors of self -sensation & decussation) are present in the joints and skeletal (striated) muscles. These receptors sense the relative position of other body parts and balance the posture. Somathesthetic sensation from each side of the body projects to the contralateral postcentral gyrus to parietal lobe, so that initially decussations must have occurred at some point along the pathway representing a muscular activity. The overall body posture and movement is balanced by the integration of information received from the vestibular system and proprioceptors by the brain. For example, the central information in playing piano is due to severe and increased stimulation of accompanying motor areas such as premotor cortex with proper planning with proprioception for decussation. But the activation of cerebellum is a bit less compared to the propriocetion. Spinocerebellar tracts are more widely projected via dorsal column and to the cerebellum and finally the information is considerably utilized for rhythmic movements. This is pathway mainly involved in the sensory ascending pathways to process sensation & perception through a 3 neuron system finally enable “sensory information” to the central nervous system through sensory receptor to the cortex. This pathway is mainly involved in mediating discriminative touch sensation through adequate proprioception & vibration. This pathway has two white matter tracts profoundly possess a first neuron mainly through fasciculus gracilis in the medial column from lower limb (T6 and lower) & sensory information is obtained through fasciculus cuneatus: of lateral column in upper limb (T5) Features of spinothalamic pathway: This is the sensory pathway mainly involved in processing sensory information of “poorly localized touch, pressure & temperature”. This pathway is going to involve cross of sensory information to the spinal cord prior to ascending via the anterior or spinothalamic & lateral spinothalamic tracts. Interaction of these two pathways: The interaction of these two pathways are mainly through axons & spinaothalamic tracts arising into an ascending pathway to transport to the sensory information processing center in the brain. Mainly spinothalamic neurons are going to use first order neurons, second order neurons, third order neurons to enter spinal cord and synapse through posterior gray horns & these neurons are going to carry sensory information of pain, sensation etc in ventral nucleus group of the thalamus. This information is going to reach through from the Lemniscal pathway finally relaye.

The various characteristics of a system can be its need, functional requirement, mission, goal, network, security controls etc. Threat identification: This refers to identification of the types of threats a system can face in an organization. The system is designed in such a way that it is able to identify the threats that might be harmful for the system that is being used. Hacking, viruses, data compromise are some of the threats that are faced by systems in an organization. Vulnerability identification: This involves identification of those areas that are vulnerable for a system. The vulnerable areas are required to be monitored closely. Control analysis: This involves controlling various functions that are related with a system and controlling them so that the system works in the way as required by a company. Likelihood determination: Likelihood determination relates with determining the likeliness that a threat may be damaging for the system. There might be likelihood that the threat might be high, medium or low as far as the likelihood of the threat from a bug is concerned. Impact analysis: This component analyzes the impact of potential threat from vulnerability. The impact analysis requires taking into account the importance of the system. In case of critical system the impact from vulnerability would be high. Risk determination: This involves determining the amount of risk involved in a system. This allows the system analysts to formulate the plans accordingly. Control recommendation: The component requires that there should be recommendations in place that would require controlling of the system so that the system works optimally and gives the desired results. Results documentation: There should be a document that should contain all the details that are related with the results that are to be provided by the system..

Numerous diseases are caused by viruses and bacteria (etc. Hepatitis, West Nile Virus, Pertussis, Avian Flu, Ebola, Cholera, Typhoid). On a Global scale, viral and bacterial diseases result in hundreds of thousands of deaths every year (sometimes millions in the case of epidemics or pandemics). However, for many of these viral and bacterial pathogens there are effective vaccines available. So, do you think the government, or your employer, or your school has the right to require vaccinations. What if your job requires you to come in contact with hundreds of people a day (nurse, bus driver, etc.). Solution The immunity against these pathogenic diseases has to develop in the children so small kids must be ensured for complete vaccination at proper ages. Vaccines for diseases like Hepatitis and Ebola are given at the early age to develop immunity for such diseases. However, those children who could not get them, should be attended by their schools through government initiatives to make sure every child get them. The jobs like nurse and drivers who happen to meet hundreds of people daily are at the greater risk of developing the diseases so their employers must take care of them..

Network peering is a method to save ISP’s network bandwidth and resources. Write a brief document describing the following: What is meant by “Network Peering” What is meant by “Internet Exchange” and How is it related to “Network Peering”. How can “Network Peering” save network resources How can “Network Peering” be implemented Solution Network Peering: Relationship between two Internet Service Providers is called Peering. In this they mutually agreed to exchange prefixes and allow flow of traffic. The typical connection to the internet is called transit. Network peering is when one internet network connects to another directly, enabling a faster throughput and exchange of information. Peering is of four types. Public peering Private peering Partial Peering Paid Peering For peering need to have connection exchange point. Internet Exchange in the context of Network Peering: To establish a peering between any two networks they must exchange the connection points. Using an Internet exchange, a network can peer with many other networks through a single connection. It is negotiable through the peer. An Internet exchange is a point of a physical infrastructure that allows different Internet Service Providers (ISPs) to exchange Internet traffic between their networks (autonomous systems) by means of mutual peering agreements, which allow traffic to be exchanged without cost. The main purpose of the internet exchange is to allow networks to interconnect directly, via the exchange, or by using other network or third party network. In establishing PEER in the network they are mutually exchanging the points to each other at that time an unlimited number of parties agree to exchange traffic on common terms, using a single agreement that they all accede to, and using a route server or route reflector. The first is a connection to an exchange point. Peering is the direct exchange of customer routing information and traffic between to isp’s..
