Explanation:

1) 72 of their chromosomes would be somatic and only 2 would be gametes. the number is always two as (normally) an organism will have either 2 X chromosomes (female) or an X and Y chromosome (male).

2) without genetic diversity, an entire species of an organism can go extinct from the same thing as none of them would have mutated any defenses and pass them off to their offspring.

hope this helps :)

Complete question: The chart shows the movement of a ball after several seconds.

Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B?

a. Column A should be “Time,” and Column B should be “Position.”

b. Column A should be “Position,” and Column B should be “Time.”

c. Column A should be “Velocity,” and Column B should be “Speed.”

d. Column A should be “Speed,” and Column B should be “Velocity.”

Answer:

Column A should be "Time," and Column B should be  "Position"

Explanation:

In general, the first column always refers to the x-axis, this is the independent variables. While the second column refers to the y-axis, the dependent variables.

Option A) names Time and Position to the columns. This seems to be correct as time is an independent variable, while the ball position depends on time. The x-axes is named "time", and the Y-axes is named "ball position".

Option B) is not possible because the Position is not the independent variable, and time is not the dependent variable.

Option C) and D) are not possible, as both of them are variables that depend on time.

A word for the first settlements, formed when humans began to domesticate plants and animals
Tamiku [17]
<span>"Village" is the term used to refer to the first settlements formed as humans began domesticating plants and animals.

A village is comprised of a clustered human settlement or community, with a few hundred to a few thousand people. It is typically smaller than a town but larger than a hamlet and is usually a permanent settlement, with dwellings spaced closely from each other. The surrounding lands were usually farmed, but in the case of traditional fishing villages, they were located adjacent to fishing grounds as well. </span>
