Answer:

The correct answer is option A. it contains fewer individuals but high genetic diversity.

Explanation:

The population with higher genetic diversity and fewer individuals will respond to highly environmental changes as if a population have higher genetic diversity will tend to adopt more changes as they have a diverse genome. The diverse genome will have the ability to adapt resistance to new diseases.

Thus, the correct answer is option A. it contains fewer individuals but high genetic diversity.

Which statement best describes how the structure of the alveoli allows the lungs to function properly

zlopas [31]

Out of the following given choices;

a. they increase the amount of energy transferred from the lungs to the blood

b. they increase the flexibility of the lungs as they expand during inhalation

c. they increase the volume of the lungs, allowing more oxygen to be inhaled

d. they increase the surface area of the lungs, allowing the efficient gas exchange

The answer is D. Due to their microscopic nature, they are numerous in the lungs and are also circular-shaped so as to increase the surface area for gaseous exchange. Other characteristics of alveoli that increase gas exchange are that they thinned-walled (with only a layer of cells) and moist.

What is the mechanism of natural selection?

borishaifa [10]

The answer is D. The natural selection is a theory which illustrates the gradual process of evolution in the population due to the change of environment. The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.

A graph titled "Average hamster weight (kg) vs. Amount of drug (mg/day)"

lakkis [162]

Explanation:

D. average hamster weight decreases with an increase in the daily amount of a drug until the hamsters reach a minimum possible weight.

Trend: There was a gradual decrease in the hamster's weight til a minimum was reached, after with the rate of its change in weight with treatment over time plateaued.

Trends are gradual notable changes or patterns over a series of data points on a line or curve of a graph. These allow for summarizing data and predicting results. A data summary provides a comprehensive report of experimental findings. This makes the analysis of data easier by answering key research objectives outlined in the experimental procedure. Summaries allow for tracking trends and procedural changes, observations and potential; this makes it easier to arrive at conclusions faster.
