No way will I give you 12 answers for two points. If you want answers spend the points and ask ONE question at a time.
The answer to 1) is c absorb nutrients.
The answer to 1) is c absorb nutrients.
1) Intestinal Villi function to
a) secrete lipids into adjacent Capillaries
b) actively transport water
c) absorb nutrients
d) assist peristalsis
2) Which liver function is most closely associated with metabolism of protein-rich food?
a) Storage of fat-soluble vitamins
b) Production of urea during the process of deamination
c) Production of cholesterol, which is released into the blood
d) Secretion of bile, which is temporarily stored in the gallbladder and then released into the duodenum

H20 + Reactants --------> Products
Enzymes
(Enzymes is actually displayed under the arrow)
3) If the reactants are protein, then the products are
a) amino acids
b) nucleic acids
c) simple sugars
d) fatty acids and glycerol
4) In an enzymatically controlled reaction, which substance is chemically latered by the action of an enzyme?
a) Products
b) Inhibitor
c) Substrate
d) Coenzymes
5) A small increase in body temperature usually increases the rate of enzymatically controlled reactions. However, a large increase in body temperature is dangerous in humans because
a) Heat will cause a change in the type of products produced by enzymes
b) most of the available energy will be used up in chemical reactions
c) enzymes will work too rapidly and produce excess products

Diarrhea is a symptom characterized by abnormally by abnormally frequent watery bowel movements (movement of fluid through the large intestine.) The danger of diarrhea is dehydration and loss of salts. Diarrhea may result from activity of the colon, faulty absorption, irritation or ionfection. (Infections are often spread by poor sanitation and contaminated food, mild, or water.)
6) What effect would diarrhea have on the production of hormones that regulate kidney function?
a) decreased antidiuretic hormone and decreased aldosterone
b) increased antidiuretic hormone and increased aldosterone
c) increased antidiuretic hormone and decreased aldosterone
d) decreased antidiuretic hormone and increased aldosterone
7) A high level of aldosterone in the kidneys will cause
a) increased reabsorption of sodium ions and increased urine production
b) increased reabsorption of sodium ions and decreased urine production
c) decreased reabsorption of sodium ions and increased urine production
d) decreased reabsorption of sodium ions and decreased urine production

Events Realted to Breathing, Arrange in Random Order
1.Nervous stimulation of the diaphragm
2.Decreased concentration of CO2 in the blood
3.Chemical stimulation of the respiratory centre
4.Increased concentration of the CO2 in the blood
5.Increased rate of breathing
8) The sequence of events which occurs as the breathing rate is increased is
a) 2,4,3,1, and 5
b) 3,4,5,1, and 2
c) 4,1,2,5, and 3
d) 4,3,1,5, and 2
9) In the blood, oxygen is primarily carried by
a) plasma
b) platelets
c) red blood cells
d) white blood cells
10) In the muscle tissues of the body, capillaries deliver
a) O2 and pick up CO2
b) wastes and pickup CO2
c) nutrients and pick up O2
d) wastes and pick up nutrients
11) The immune system not only combats viruses and bacteria, it also protects the body from cancer. The type of white blood cells that destroy cancer cells are
a) helper B cells
b) helper T cells
c) killer (cytotoxic) B cells
d) killer (cytotoxic) T cells

Alberta populations of woodland caribou have been in the past several years. One major influence has been the logging of mature forests which contain lichens necessary for caribou to survive the winter.
The young regenerated forest provides good food supply for moose, deer and elk, which, in turn, will attract and support the growth of a wolf population which preys on the caribou.
Oil and gas activity in these logged areas further increase human contact with the caribou and increase poaching and accidental deaths. The wolves use cutlines and skidoo trails to increase their hunting range.
The table below shows the changes in the populations of animals in the time following the logging of a mature forest
