D- The small intestine is very long and thin. This helps increase the amount of surface area of the small intestine, so it can fully absorb the nutrients in the food. The villi are thin walled to allow the most amount of nutrients to be absorbed as possible.

The correct answer is:

D .Villi in the small intestine have thin-walled capillaries to make the absorption of nutrients more efficient.

Explanation:

The small intestines are well adjusted for absorbing nutrients during digestion by being very long, having villi and microvilli that enlarge surface area, using muscular contractions to move and mix food, and raising and housing digestive enzymes and bile that aid the breakdown of food. The inner surface of the small intestine is not flat but thrown into circular folds, which not only enhance surface area but aid in preparing the ingesta by acting as baffles. Villi: the mucosa makes multitudes of ridges which project into the lumen and are satisfied with epithelial cells.

The relationship between population growth and resources can be described as
Lina20 [59]

A

The relationship between population growth and resources is inverse; as one goes up the other goes down.

Explanation:

An inverse relationship is one where when one variable is affected positively, the other is negatively impacted, and vice versa. In other terms, when one variable increases the other decreases.

When population growth increases, the strain on the resources increases, due to increased competition, and hence the resources decrease. This is why ideally apopulation cannot grow indefinitely because resources are always limited. The population growth will start to levels off as it reaches carrying capacity. When the resources become depleted the population growth plummets.
