How many membranes does the chlorplast have?
a. 1
b. 2
c. 3
d. 4

B

Explanation:

Chloroplasts have two membranes: external and internal membrane. These membranes contain 60% of lipids and 40% of proteins, just like the typical cell membranes. The inner or internal membrane is virtually non-permeable to any substances but it has transport proteins, on the other hand, the outer or external membrane is permeable to most of the small molecules

loss of sensation to pressure and touch

the dorsal column–medial lemniscus pathway (dcml) (also known as the posterior column-medial lemniscus pathway (pcml)) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints.
