False

10) Which of the following biological molecules is amphipathic and a major component of the cell wall?

Select one:
a. cholesterol
b. phospholipids
c. proteins
d. carbohydrates

Answer 1

1. a) mixotrophs.

This protist can do photosynthesis, so it is a autotroph. On the other hand the protist can absorb nutrients from dead organisms, so it is a heterotroph. As the protist show the property of both autotroph and heterotroph, we call them mixotrophs.

2. d) all the above.

3. d) all the above.

4. True.

5.

6. d) aerobic cellular respiration.

7. False.

8. b) tropical rain forest.

9.

10. b) phospholipids.

In the question, instead of cell wall, it should be component of cell membrane.
