An ovarian cell receives a series of endocrine signals from the pituitary gland to start producing hormones at a cytoplasmic receptor protein. These hormones also have cytoplasmic receptors. To accommodate this increase, the ovarian cell starts to produce large amounts of mRNA. Which of the following would be observed as the cell produces more ribosomes?

The nucleus produces large amounts of tRNA for ribosomal proteins.
The nucleolus produces large amounts of rRNA and sends it to the cytoplasm.
Ribosomes floating in the cytoplasm exceed the amount of available mRNA.
Ribosomes floating in the cytoplasm not bound to mRNA bind to the endoplasmic reticulum.

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
