QUICK ASAP PLS Certain bacteria live and grow on the roots of some plants and produce chemicals that are beneficial to the plants. Which of the following observations best supports the claim that this relationship is beneficial to the plants?



Group of answer choices

Plants with a higher amount of the bacteria on their roots have increased rates of survival and reproduction.

When the bacteria are removed from the plant roots and are grown in a laboratory setting, they fail to survive.

The population size of the bacteria varies greatly depending on the chemistry of the soil and the type of the plant.

The chemical produced by the bacteria can be created by humans and added to the soil where it reaches the roots of the plant.

Answer:

Explanation: Plants with a higher amount of the bacteria on their roots have increased rates of survival and reproduction.

Which graph represents selection that may lead to reduced variation in a population? A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population and population after selection have similar curves, but the original population peaks before the population after selection. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The population after selection increases, decreases, increases, and then decreases again. The original population increases at the point that the original population drops. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population peaks at the same time as the population after selection but the population after selection peaks higher and at a more rapid speed. A graph has trait value on the horizontal axis and proportion of individuals on the vertical axis. The original population and population after selection have similar curves but the original population is slightly higher at all points. Mark this and return
