Question 4 (2.5 points)
In the hospital’s post-op recovery ward, patients are comparing the consequences of each having an organ removed.
Question 4 options:
1234 Ann: “Now that my ________ is gone, I should have few problems, since it doesn’t secrete enzymes and has just a minor role in immunity.”
1234 Devonne: “You can’t survive without a ________. Luckily they only removed part of mine, so the remainder will still be able to remove toxins, produce bile, distribute nutrients, and synthesize blood proteins.”
1234 Carlos: “Few people have to have their ________ removed. I will have serious problems with digestion and blood sugar regulation, so I’ll need enzyme replacement therapy and insulin injections.”
1234 Bill: “Coping without a ________ will be a little annoying. I need to avoid high-fat meals because the bile won’t be stored and released at the right time.”
1. appendix
2. gallbladder
3. pancreas
4. liver
Question 5 (2.5 points)
When you become dehydrated, and the osmolality of the blood increases (meaning your blood has more salt and less water), osmoreceptors in the hypothalamus cause the posterior pituitary to secrete anti-diuretic hormone (ADH). ADH acts on the kidney to increase the reabsorption of water, and put the water back into your bloodstream. This helps prevent the osmolality of the blood from increasing even further. If you drink lots of water, ADH production decreases, and the kidneys remove water from the blood, again maintaining the osmolality of the blood.
What is the receptor?
Question 5 options:
A. osmoreceptors
B. pituitary gland
C. ADH
D. kidney
E. blood
F. hypothalamus

Question 7 (2.5 points)

A. biological, volcanic, and precipitation
B. physical, chemical, and biological
C. temperature, gravitational, and relative humidity
D. weathering, temperature, and hydration
E. nuclear, gravitational, and chemical
Question 8 (2.5 points)
Leaves have air spaces to allow for carbon dioxide and oxygen to move into and out of cells for photosynthesis, which causes water to evaporate and creates greater tension on the mesophyll cells. How do xylem vessels and tracheids prevent collapse in these conditions?
Question 8 options:
A. photosynthesis is reversed at times to bring together oxygen and hydrogen ions
B. metabolic dehydration reactions provide excess water to replace it
C. the turgor pressure of surrounding cells pushes the mesophyll cells into shape
D. lignin keeps water flowing through the cells
E. rings maintain their tubular shape
