AUA Is the Cup Half Full or Half Empty Primate Ecology Discussion.
Of the nearly 600 species and subspecies of primates living today approximately half are in danger of extinction. The number of recognized serious threats to primate survival has increased over the last decade. they include climate change, habitat loss ( encroaching farmland, deforestation, logging industries). and bushmeat hunting. Also, primate diseases, particularly for those populations that are in danger of contracting diseases from exposure to humans through ecotourism is on the rise. How have your perceptions of these threats changed, and reflect on whether the situation is hopelessly grave (the cup half empty) or there are reasons for optimism (the cup is half full).
Please no plagiarizing, but this is just a discussion post so the more info the better!

Grossmont College Gene Disorders Hit Amish Hard.
Before you begin the assignment make sure you view the video “Gene Disorders Hit Amish Hard” and make sure you read this week’s PDF “Evolution and its Mechanisms”
Genetic Drift Webquest
The Amish in the US began as a small group of Swiss-Germans that immigrated to the US in the 1700’s. Over the course of a few centuries they grew from a small founding population of 200 to a current population of more than 250,000. The most interesting thing about the Amish is that it’s a religious group that has remained culturally isolated and by extension, genetically isolated from the rest of the country. This genetic isolation from other humans has lead to an unprecedented amount of genetic disorders among the Amish.
Physicians were initially exposed to the genetic problems plaguing the Amish in the 1960’s. When the Amish began to reach out to the medial community doctors discovered that there were an unusual number of rare genetic diseases. One of these visible and rare genetic disease was called Ellis-Van Creveld syndrome. What was surprising to medical geneticists was not the presence of the rare genetic disease but rather how many Amish had the disease in the first place. Basically, the Amish in Lancaster County, Pennsylvania had more cases of Ellis-Van Creveld syndrome than all other human in the world combined! What was even more surprising was the fact that there was not just one rare genetic disease but rather dozens of rare genetic disease (In this context, rare genetic disease means that there may be less than 150 humans in the planet having the disease). Even more unfortunate is the fact that there are hundreds of other genetic disease associated with the Amish.
The big question that the Amish wanted to know was, why do they seem to have an unusual share of genetic disease when compared to the non-Amish and how do they stop those genetic disease in the first place!
What you are doing
- Your task will be to investigate a rare genetic disorder found among the Amish and to use evolutionary theory to both, help you understand why genetic disease can become common among isolated populations and to see how evolutionary theory can assist in curbing prevalence of genetic disease.
Before you begin your task make sure you do the following things.
- Read lecture notes on evolution. Especially the ones pertaining to Genetic drift.
- Watch video on Amish genetic diseases.
What you need to do
Before you begin this assignment, I recommend that you clearly understand what evolution is (a change in allele frequency from one generation to the next). Make sure you use the information provided and give me informed ideas that are based on your understanding of the subject matter. For this assignment you will have to answer the following items:
- Pick and a rare genetic disorder that is common among the Amish and tell me how common the disease is around the world vs among the Amish? Give me estimated percentage of afflicted individuals! (I don’t need to know details of the genetic disease just its name). The important idea is to understand why disease associated alleles are found in high frequencies in the first place!
- Explain in evolutionary terms why the genetic disorder that you investigated is found in unusually high frequencies among the Amish in the first place. You will need to give me one evolutionary mechanism that can specifically explain the Amish issue. Make sure you name the evolutionary mechanism and give a quick explanation of how the evolutionary mechanism works.
- Explain how the Amish might be able to curtail the incidence of your chosen genetic diseases using evolutionary knowledge. You will need to give me one evolutionary mechanism that would be able to fix the Amish dilemma. Make sure name the evolutionary mechanism and give a quick explanation of how the evolutionary mechanism would be able to work.
- Lastly, remember to cite all your work!

3 Discussion Posts About Multiplicity In Thermodynamics.
3 discussion posts, each 150 words
1- Microstates of the ideal gas
2- Multiplicity: Simulations
3- Sharpness of the multiplicity function
This thread is for the discussion of the derivation and meaning of the sharpness of the multiplicity function (of which the meaning is far more important!). How does he sharpness of the multiplicity function for 100 coin tosses differ from the sharpness of the multiplicity of an Avagadro’s number of coin tosses? What does that imply for the probability of the “all heads” macrostate? What does that imply for the second law of thermodynamics? How often should we expect to see the second law violated in macroscopic systems? What are thermodynamic fluctuations? Should we be able to measure them? What is the thermodynamic limit?

BSC 2086 FSCJ Pulmonary Hypertension in Children Discussion.
Malformations in the lymphatic system, called lymphangiomas, are overgrowths of the one-way lymph channels. Rarely, in infants and children, these channels grow abnormally large and cause deformity or death if the overgrowth chokes off a child’s airway or interferes with other aspects of heart and lung function. The deformity tends to grow with the child, worsening over time and is difficult to treat.
Physicians at Lucile Packard Children’s Hospital at Stanford (Links to an external site.) discovered, essentially by accident, that a common drug – sildenafil, a.k.a. Viagra – appears to shrink the overgrown vessels. They gave sildenafil to a child with a severe lymphangioma to treat another condition, pulmonary hypertension, and noticed that the lymph malformation shrank significantly. Unfortunately, the child’s underlying condition was so severe that she later died; however, two subsequent patients have done well on the medication.
“There has been no medical treatment for lymphangiomas; now all of a sudden there may be one,” said Al Lane, MD, a co-author on the NEJM letter published January 2012 and an investigator on the lymphangioma research now being conducted. The mechanism by which the drug could resolve the malformations is not known, however there’s a possibility that sildenafil may help to open and drain the channels,” Lane said.
The drug (Viagra) has been used to treat pulmonary hypertension in children. Its typical side effects in children are nausea, headaches and cold-like symptoms such as a runny nose or fever, Lane said. Spontaneous erections are possible but are an infrequent side effect. Discuss your thoughts on studying and utilizing Viagra as treatment for lymphangioma and its side effects in children.

Hooke Law Magnetic and Gravitational Force Lab Report.
Force is a push or pull on an object in simple terms. There are forces all around us. Some forces we can see and some we can only see act on other objects. For example, if I throw a ball, I apply a force to the ball with my hand. There are unseen forces such as magnetic and gravitational. If I let go of the ball, it will drop to the floor. I cannot see the gravitational force, but I can see the ball fall to the floor. The Earth pulls the ball to the floor. If you hang an object on a spring, there are two forces involved. The Earth pulls down on the object and the spring pulls up on the object. Robert Hooke found a relationship between the force on the spring and how far it stretches. We are going to study this relationship.

Mars Voyage Trip Resources Astronomy Research Assignment 2.
In this portion of the lab students will focus on what resources will be needed for a trip to Mars. To simplify things we will only look at three specific things-food, water and oxygen. For food, specific foods will not be looked at, but only food in general: how much food (in mass) does an astronaut consume per day. Likewise we will focus on how much oxygen and water are needed on a daily basis. This research will be conducted on the internet, so remember to cite all your sources. If it did not come out of your head, you need to cite it. Also, do not, repeat, do not ever, use wikipedia as a citable source. You can go there and get ideas, but must find them somewhere else before you use them. Wikipedia is unreliable.

BIO 111 Oragnic Gradenning Discussion.
1- Let’s say that Toronto University starts a food sustainability and diversity project next spring (in 2021). One of the proposed gardening activities is to transform a sunny section of the quad to grow Montreal melons. The melons would be served to the community in September 2021, to kick off the new academic year… with “fully normal” in-class courses (because an effective vaccine has been discovered and is widely available).
The quad area was selected because it is quite large and central, water is accessible, site is very sunny and warm, and nearby buildings block winds. Melons don’t grow well under cold and windy conditions. They grow well in light, deep soils, enriched in humus. In terms of nutrients, melons are nutrient needy. Their ideal soil pH is between 6 and 7.
Early in spring 2021, some tests are performed to assess soil characteristics in the quad. The pH is 6.25. Soil is clayey, rather compact and not very permeable. Major nutrients are deficient.
Given this context and test information, which general category of treatment is most recommended? Explain briefly (justify your answer)
2-Using your class notes or chapter soil health, identify specific treatment(s) for melon culture in quad soil. Explain why you recommend this/these treatments. Explain two goals of the proposed treatment(s).
3-Given the site characteristics, identify a plant pathogen that could be problematic over the long growing season. Explain briefly why you think it would be problematic. Propose also a preventive measure to avoid or minimize this potential problem.
4-Let’s say a university would like to adopt a plant as floral emblem. The University consults the community to identify a plant that represents it well. What would you suggest? Explain briefly your choice by giving up to 2 arguments.
