Succulent plants such as aloes are known for their thick stems and leaves, which allow them to store water. Which statement best
Marina86 [1]

Answer:

D. Thick stems and leaves were selected because succulents with these characteristics are more likely to survive hot, dry weather and, thus, produce more offspring

Explanation:

The succulents have not always been as they are now, but they have evolved from plants that looked different and existed in different weather conditions. As the environment has been changing, in order to survive, the succulents started to develop traits that would be advantageous for them to survive in the hot and dry weather. The succulents that started to develop such traits, like the thick stem and leaves were the ones selected to survive, as they were the ones that had the advantage in this type of environment. The thick stems and leaves enabled them to store as much water as possible when there is, and also to preserve it for long periods of time, while the succulents that didn't possessed this traits died out because they were not able to sustain the new conditions, nor to be able to reproduce effectively.

Countercurrent multiplication involves A) ions leaving ascending limb to make water come out of the descending limb B) water lea
Snowcat [4.5K]

Answer:

The correct option is A

Countercurrent multiplication is the process whereby energy is used to generate an osmotic gradient in which water is reabsorbed from the tubular fluid to produced concentrated urine.

Explanation:

Countercurrent multiplication moves sodium chloride from tubular fluid into interstitial space deep within the kidneys. The concurrent multiplication process build up osmotic gradient interstitial fluid in a single effect. Here, sodium chloride is driven by active transport out of the tubular fluid in the thick ascending limb into the interstitial fluid, which becomes hyperosmotic. This result to water moving passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space to a point where it attains a state of equilibrium.

Therefore,the correct option is A, where the ions leaves the ascending limb to make water comes out of descending limb.
