Elastic fibers are important to muscle tissue since they resist excessive stretching and help muscle fibers spring back to its o
brilliants [131]

Answer:

True

Explanation:

Elastic fibers are composed of elastin, myofibrils and fibrillin. They are distributed <u>separately</u>, and therefore do not form bundles(they actually form a kind of mesh), like collagen fibers.

Elastic fibers are usually thin and long and can stretch up to 1.5x of their total length.

These fibers confer elasticity to the connective tissue. The mesh formed of elastic fibers easily yields to minimal tensions, returning to its original shape as soon as the deforming forces cease.

An example of the action of elastic fibers is when we pull the skin from our hands and release it, the elastic fibers are responsible for quickly returning the skin to its original shape.

GenaCL600 [577]

The correct answer is D. These is large amount of biodiversity in the chaparral

The chaparral biome consists of different types of terrain such as mountains and plains. This biome is similar to the desert biome due to hot and dry conditions prevail in both the biomes, but chaparral biome receives more rainfall than the desert biome. This biome is characterized by having both forests and grassland with a large amount of biodiversity. The vast biodiversity  insulate the biome from loss of single a single species.
