Answer:
Phospholipids form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane
Answer:
The sympathetic chain contains a group of cell bodies called the sympathetic chain GANGLIA. This structure contains a second cell body for the sympathetic nervous system, the first in the series being found in the THORACOLUMBAR REGIONS' lateral horn of spinal segments T1-L2. The purpose of the VENTRAL AND DORSAL rami is to carry visceral motor and visceral sensory neurons to and from this sympathetic chain.

Answer;
B. Speciation
Explanation;
-Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
-The demands of a different environment or the characteristics of the members of the new group will differentiate the new species from their ancestors.
-An example of speciation is the Galápagos finch. Different species of these birds live on different islands in the Galápagos archipelago, located in the Pacific Ocean off South America. The finches are isolated from one another by the ocean.
