providing molecules needed for the synthesis of fats in human
cells?
1. digestive and circulatory

12. 18. An individual who has had chicken pox rarely gets
the disease again. This situation is an example of
1. biological control 3. active immunity
2. negative feedback 4. passive immunity
13. to
1. 2. 3. 4. A pulse can be detected most easily in
1. an artery 3. a capillary
2. a vein 4. a lacteal
The main function of the human digestive system is
19. rid the body of cellular waste materials
process organic molecules so they can enter cells
break down glucose in order to release energy
change amino acids into proteins and carbohydrates
The breaking apart of platelets in the blood helps in
the
14. transported throughout the body, but the hormone affects only
certain cells. The reason only certain cells are affected is that
the membranes of these cells have specific
1. receptors 3. antibodies
2. tissues 4. carbohydrates
15. A marathon runner frequently experiences muscle cramps while
running. If he stops running and rests, the cramps eventually
go away. The cramping in the muscles most likely results from
1. lack of adequate oxygen supply to the muscle
2. the runner running too slowly
3. the runner warming up before running
4. increased glucose production in the muscle
16. 1. 2. 3. 4. After a hormone enters the bloodstream, it is
In a human, the movement of glucose from the
digestive tract to muscle cells is most directly a result of
1. ingestion and digestion
2. absorption and circulation
3. anaerobic respiration
4. protein synthesis
20. synthesis of hemoglobin
formation of a clot
release of antibodies
deamination of amino acids

lunch. Which sequence represents the correct order of events
in the nutritional processing of this food?
1. ingestion → digestion → absorption → egestion

primarily functions of
1. muscles 3. cartilage
2. tendons 4. bone
22. An allergic reaction to certain types of natural,
unprocessed foods, such as peanuts, is caused by
1. a lack of digestive enzymes
2. a response to specific antigens
3. microorganisms living within the food
4. high levels of carbon dioxide in the air
23. Cells of the immune system are able to respond to
the presence of invading organisms because they recognize the

he is not immune to the avian influenza virus.
3. He will not have the symptoms of the bird flu because he
is immune to rhinovirus A.

because the avian influenza virus causes it.
