Demography is the study of human population dynamics. It entails the study of the size and density, distribution, and vital statistics such as births, marriages, deaths, aging, migration among other factors that affect a population.

My 2 cents below, I tried to think through the other ones:
A. Yes, because an amino acid change has occurred.
(A gene mutation occurred, not an amino acid change)
B. Yes, because all mutations change the resulting protein.
(Sounds correct. Gene -> mRNA -> protein)
C. No, because the amino acid sequence has not been changed.
(The gene mutation means the amino acid sequence <em>has</em> changed)
D. No, because mutations in the DNA do not affect the mRNA sequence.
(They do so)
Answer:
crossing over
Explanation:
This occurs during prophase I and metaphase two of the cell cycle. Two homologous sister chromatids pair up and exchange DNA in order to increase genetic variation.
The respiratory system and digestive system both use the throat, also known as the pharynx.
Hope this helped.
