Answer:
A. much of the variation in individuals of a population is heritable
Explanation:
Charles Darwin is a scientist well known for his development of the concept of evolution. Darwin was able to deduce that the species of a population have a common ancestor and that as time passes there is a modification in the characteristics of these species that makes it easier for them to adapt to their environments. These traits that were inherited from past descendants, were helpful traits that made it possible for their own descendants to be able to survive better than their peers. He noted that there were limited resources for survival, therefore it was a case of the survival of the fittest.
Natural selection was the term used by him to describe how species of a population survived over time. Members of a population had varied traits that enabled them to survive. For example, the descendants of an ancestor could have slightly different shapes, colors, sizes, and other features but still maintain traceable heritable traits.
B.) Adenine because Dictated by specific hydrogen bonding patterns, Watson-Crick base pairs (guanine-cytosine and adenine-thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence.

Answer:
Due to lack of expansion of lungs.
Explanation:
The lack of surfactant compound would result in respiratory distress because Surfactant enables the lungs to expand more easily which allows easiness in respiration. Without surfactant, the air sacs in the lungs will collapse very easily. This collapse leads to decreased amounts of air or oxygen in the lungs which makes it very difficult for the people or infant to breathe.
