What is the main idea behind the model of a molecular clock?
a. that neutral mutations accumulate at a steady rate
b. that certain traits are under the pressure of natural selection
c. that segments of DNA can be compared with segments of RNA
d. that phenotypes, not genotypes, are affected by natural selection

The response that we could expect to happen as the body tries to restore homeostasis is : A. Cells swell as water moves into them

The Water molecules will move from the one with high concentration to the low concentration area (in this case, this is the cell), causing it to swell

hope this helps
