Answer:
A. map
Explanation:
DNA acts as a map for living things.
Answer:
This situation is an example of; b. natural selection.
Explanation:
Natural selection is the mechanism of evolution that selectively reproduces hereditary variants (genotype) to make an organism to become well adapted or highly-suited to its environment over time. The selective hereditary variants in the genetic constitution of the organism increase the organism’s chance of survival and reproduction, and these variants are preserved and multiplied from generation to generation than the less beneficial ones.
From the question, the dark color of the population of the termites is a beneficial hereditary variants that increase their chance of survival because it protects the termites from predatory species. Due to natural selection, the dark color trait is preserved and multiplied in the termite population for several generations. This is why the termite population consists almost entirely of darkly colored members.

Answer:
c. Factors 1 and 2 may be influenced by both nature and human factors
Explanation:
The sea level rising and the change in the atmospheric gases are both processes that are influenced by the nature, as well as by the human activities. Naturally, the earth has its own cycles, known as Milankovich cycles, through which the Earth warms up, or cools down, resulting in change of the atmospheric gases, and in accordance to that, change in the sea levels depending on the global climate. The humans to have become a big factor in the past few hundred years. The reason for that is that the humans with their activity started to release lot of greenhouse gases into the atmosphere, especially CO2 and methane. That has been changing the composition of the atmosphere, and the temperatures have been rising. The higher the temperatures, the more ice is melting around the poles and on the high mountains, resulting in an increase in the sea levels.
