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.

vampirchik [111]

Answer:ways Water enters the atmosphere evaporation, transpiration, excretion and sublimation:

Explanation:

Transpiration is the loss of water from plants (via their leaves).

Sublimation is when ice or snow transforms directly into water vapour without going through a liquid phase (i.e. they do not melt).

Animals excrete water by respiration and by passing urine.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.

sleet_krkn [62]

Answer:

The correct answer is option - D. phosphorylation.

Explanation:

The CARD11 or caspase recruitment domain-containing protein 11 is a gene that provides instructions for gene expressing to make a protein in the function of lymphocytes in the immune system. Lymphocytes like B and T cells are activated with the help of cascade reactions in which these genes provide information.

The protein that activates is PKC which is a kinase enzyme that implicates that the process that activates CARD11 is phosphorylation.

Thus, the correct answer is option - d - phosphorylation.
