The structure shown by the red arrow is cell membrane.  

In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:  

1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.  

2. It prevents toxic components from entering the cell.  

3. They distinguish essential but incompatible metabolic procedures conducted within the cell.

Looks like a cell membrane. So the function would be to control what goes into and out of the cell.

mrs_skeptik [129]
It depends on how many points out of how many points you had to get the 87.29%

But I think your grade is a B....

89.95% and up = A
79.95% to 89.94% = B
69.95% to 79.94% = C

so yeah

Dark pigments are more common in endotherms from humid environments than dry ones is know as .
Lady bird [3.3K]

According to Gloger's rule, endothermic creatures should have darker hues in hot, rainy areas. The so-called complex Gloger's rule also states that animals should be more rufous in warm, dry regions.

Explains the connection between animal color variation and large-scale climate gradients. Bernhard Rensch gave it that name in 1929 to honor Constantin W.L. Gloger, who was one of the first to write about relationships between animal pigmentation and temperature in 1833.

Gloger's rule, as it is known now, states that mammals and birds should be darker in warm, humid settings than in colder, dry ones.

Gloger's rule-related color variation is mostly caused by variations in melanin pigmentation, according to this quick reference.

The most prevalent pigment in birds and mammals, melanin's are of two primary types: pheomelanin's, which produce brown, buff, and rufous colors, and eumelanin's, which produce black and different shades of grey. Both generate intermediate hues when combined.
