Question 9

21. If a cell failed to go through DNA replication prior to mitosis, what would be the resulting issue with the daughter cells?

Answer 9

It does not have enough DNA

Question 10

24. Explain the structure of the cell membrane. Include two macromolecules that are embedded within it, the polarity of different parts of the membrane, and why this makes the membrane selectively permeable.

Answer 10

The membrane is made of two layers of phospholipids that contains proteins. It is very picky that makes it selectively permeable.

Answer 24

lateral to the sternum, medial to the left arm

Question 25

38. Describe the difference between how negative and positive feedback loops help maintain homeostasis. In your answer include
    a. how the output affects the the input
    b. a real world example in humans

Answer 25

Negative puts you back to normal and positive feedback keeps on going and magnifies

Question 26

41. Is the receptor protein in the figure from #39 an intracellular receptor or a membrane receptor? Explain how you know.

Answer 26

It is a membrane receptor because it starts outside the barrier and makes its way in.
