Question

A scientist runs a chemical analysis of two nerve tissues. Tissue A contains a greater composition of fat and protein than tissue B. What is the identity of the two tissues?

a. A = meninges; B = neuron bodies
b. A = neuron bodies; B = meninges
c. A = gray matter; B = white matter
d. A = white matter; B = gray matter

Answer 1

A = white matter and B = gray matter

Step-by-step explanation:

White matter and grey matter are one of the most important components of the brain. Grey matter refers to the the neurons that are unmyelinated and present in the brain stem and cerebellum as well. White matter affects the learning process of individual.

The nerve tissue analysis shows that Tissue A has great fat and protein composition. This tissue is white matter because whit matter is in color due to the presence of fats. Tissue B is grey matter as it darker in color and has low fat and protein composition as compare with grey matter.

Thus, the correct answer is option (d).

Answer 2

The correct answer for this question would be option D. Based on the results that the scientist did when he ran a chemical analysis of two nerve tissues, the identity of the two tissues would be A is white matter and B is gray matter. White matter is found in the deeper tissues of the brain and is surrounded by the myelin sheath. Gray matter is the darker tissue. Hope this answer helps.
