Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Fittoniya [83]

Answer & explanation:

Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.

In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.

In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).

Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.

dsp73

Answer:

C

Explanation:

The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.

A) The Dura mater

B) The arachnoid mater

C) The pia mater

The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.

The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.

The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.
