Genetic Drift

Explanation:

Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance or sampling error. Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations. This process may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100% frequency, of other alleles. It also have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).

Which is represented by the arrow labeled 1 in the diagram? A.
Water is running and collecting along the surface.

B.
Water is absorbing heat energy and changing from a liquid to a gas.

C.
Water is releasing heat energy and changing from a gas to a liquid.

D.
Water is being absorbed into the ground.

Answers

B.

So in the diagram, you can see that the water is evaporating. To make the water change state, you must break the bonds between the water molecules in the liquid and make it a gas. Therefore that answer is B

How much do landscape features on the moon change overtime compared to landscape features on Earth? Explain your
answer.

Answers

Landscape features on the earth changes constantly because of the movement of crust, erosion by water and wind, and living organisms.

The surface of the moon changes slowly because none of these factors are active. In other words, the moon is “dead” geologically with little tectonic activity. The moon also does NOT own an atmosphere like how the earth does. There is no life on the moon.
