6. What features are necessary for the cell to engage in facilitated diffusion rather than simple diffusion? Secondary active transport rather than primary active transport (is this different for symport and antiport? What advantages do we derive by putting these modifications in place?
2. Make a concept map of the cell membrane. Include each of the functions of the cell membrane listed below. Make sure each function is correctly linked to the components of the cell membrane responsible for each function
7. In mythology, the cosmic man appears grossly swollen and may be seen pictures as a human rain cloud. Propose a mechanism whereby this mythological creature could swell up and fill with water. (It is not going to be true, so you can’t look this up – it’s just for fun to see if you understand how it could work.)

Discuss information technology~ collection, modeling, and surveillance of disease agents.
1. Expound on one of the following disease and the use of technology in disease surveillance:
The flu epidemic, Malaria, Measles, Zika Virus, HIV, Typhoid, or other globally impacting disease. What goals/procedures would you recommend in the event of a global epidemic?
2. What roles do social inequality and absolute poverty have as determinants of health? What roles does information technology play in global public health? (May need to give examples)
3. What is the role of computers in modeling natural disasters? What is the healthcare professional's responsibility in disasters (natural and human-made) such as Hurricane Katrina and the Deep Horizon oil spill?

The lymphatic system includes our bodies' defenses against infections. AIDS, Leukemia, many autoimmune disorders, and allergies are all manifestations of a breakdown in the normal functioning of the lymphatic system. Find an online source that helps to explain how these diseases interact with the lymphatic system mechanisms. Provide the link and a brief summary of fewer than 250 words. Then, read at least two classmates' posts. What questions are you still wondering about after reading the summary they posted?

Average blood velocity is 11cm/s in the human ascending aorta. The average diameter of the aorta is 2.1cm.
a) How much blood passes through the aorta each day in gallons?
b) How does this compare to the total quantity of blood you have in your body?
c) If 45% of the aorta becomes clogged, what is the new blood velocity?

2. How do cardiac muscle and skeletal muscle differ in the role of Cain stimulation of muscle fibers? How does this difference affect the changes in membrane potential in cardiac muscle?
3. Based on the information in questions 1 and 2 explain why cardiac muscle does not demonstrate tetanic muscle contractions
