How can it be determined if an apparently normal dog is carrying a gene for deafness?
Phenylketonuria (PKU) is a defect of amino acid metabolism inherited as an autosomal recessive trait. Untreated children are usually severely mentally retarded. If two phenotypically normal parents have a PKU child, what are the genotypes and phenotypes of their children and in what portions?
Cystic fibrosis, inherited as an autosomal recessive trait, involves a defect of glycoprotein metabolism. Phenotypically normal parents had two children, one normal, one with cystic fibrosis. Write the probable genotypes for the parents
In man, hemophilia (failure of the blood to clot normally) is inherited as an X-Linked recessive trait. A woman has one hemophiliac son. Write the genotypes for the women, her son, her normal husband, and other children the women might have.

2. Explain how lymph is formed. What would be the impact on lymph formation if the osmotic force at the venous end of the capillary was more successful at recovering fluid lost at the arterial end?
1. The causative organism of tuberculosis has a coat around it that makes it much more resistant than other bacteria to digestive enzymes and hydrogen peroxide. What can you say about this characteristic, and why is it more difficult for the body to fight off these bacteria?
3 . How would you explain how the various types of T cells can fine-tune the immune system?
4 . Why do you think the development of cancer can be seen as a failure of the immune system?
7 . If the genes that produce Toll-like receptors (TLRs) were abnormal, what effect might have on a person’s immunity?

- Identify the endogenous molecule that the drug is interacting with and how it changes its function.
-Discuss the changing synaptic transmission by drugs based on the neural circuits that are affected.

A 70 kg man wants to lose 10 lb. His schedule allows him to exercise for 45 minutes on 3 days per week. His VO2 Max is 52ml/kg/min. He says he can comfortably run on a treadmill for 45 minutes working at 70% of his VO2 Max. Prescribe what his workout should be (i.e. treadmill speed) if he works out on a treadmill. What would an equivalent work rate be if he has to use a cycle for the same amount of time. How many weeks would it take for him to lose 10 lbs. given that 1lb = 3500 kcal?
