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.

Acid-fast and Gram is used to visualize the structures in a membrane.  

It is a differential staining procedure which is used to identify, <em>mycobacterium tuberculosis and M. leprae.</em>

Acid-fast bacteria are considered to be gram-positive in terms of their structure as, they contains peptidoglycan in its cell wall.

They stain poorly with Gram stain procedure, and appears as weak Gram-positive.

Membranes are consisted of lipid bilayer, which is doubled layer of phospholipid, glycolipid and cholesterol molecules, which contains the chains of fatty acids,  and

<em>determines weather a membrane is formed into long flat sheets or round vesicles.</em>

To examine the membrane protein structure, Electron microscopy technology is used and it enables the visualization of single protein at nanometers resolution.
