No. Below 1000m the sunlight could not reach therefore plant like organism would not be able to grow there. However if the organism does not need sunlight then it might have a small chance of survival. Of course there also is the water pressure that can also pose a problem. So I say No.
AnsweR:
Rough endoplasmic reticulum.
Explanation:
The endoplasmic reticulum is a member of the endomembrane system and is present as a continuation of the nuclear membrane. They are divided into the rough endoplasmic reticulum and smooth endoplasmic reticulum.
Rough endoplasmic reticulum has ribosomes on its surface and is responsible for the synthesis of secretory proteins. Smooth endoplasmic reticulum synthesize lipids.
Therefore cells that intensely biosynthesize secretory proteins like neurons, white blood cells have a greater amount of rough endoplasmic reticulum than another cell of the body.
The opposite of synthesis is decomposition which involves the breaking down of elements or compounds or molecules into simpler ones. So, B.
