5. Many medical schools are realizing the importance of integrating the principles of evolutionary biology into the study of medicine. What are some of the strong justifications that future physicians have a clear understanding of evolutionary theory to help them understand the nature of infectious diseases, emergence of autoimmune diseases, implications of genetic engineering, and value of medical research on non-human organisms.

Describe some transformations which are rigid transformation?

1. As a scientist working in a government lab, you have been given full control over the production of a new compound. The compound was isolated from the horse chestnut tree, a tree which only grows throughout 20% of the world and reaches maturity in 75-80 years. It was found that only the flowers contain the compound of interest (shown to the right). Choose whether you would extract from the natural source or chemically synthesize the compound. Explain and justify three reasons that support the choice you made and one reason, that is different than anything you mentioned, why your choice might not be the best – detail required in all answers (9 marks)

Your telescope has an objective lens with a focal length of 1.0 m.You point the telescope at the moon, only to realize that theeyepiece is missing. Even so, you can still see the real image ofthe moon formed by the objective lens if you place your eye alittle past the image so as to view the rays diverging from theimage plane, just as rays would diverge from an object at thatlocation.
What is the angular magnification of the moon if you view its realimage from 25 cm away, your near-point distance?

there are 4 stages in muscle contraction: excitation, excitation-contraction coupling, contraction, and relaxation.
a) briefly describe the molecular process of excitation, beginning at the synaptic bulb of the neuron. how does this affect the muscle fiber?
b) how is calcium released from the sarcoplasmic reticulum during excitation-contraction coupling, and how do troponin and tropomyosin regulate the interaction between myosin and actin
c) describe the events of one cross-bridge cycle and how this shortens the sarcomere.
d) following contraction, what events must occur to allow the muscle to relax?
