The answer would be:
C. Transcription
Here's a little more about gene regulation:
Gene regulation as mentioned already, is the process of turning genes on and off. In multicellular organisms, the different cells have the same DNA in them but through gene regulation, different sets of genes are expressed. The genes that are expressed determine the function and appearance of the cell.
Organisms need to take food because you need it to survive.
Autotroph --
<span>Autotroph is </span>an organism that can form nutritional organic substances.
The food chain would most likely collapse slowing, without a producer other animals cannot get the needed nutrients required to survive.
Answer:
b. synthesis of cellular membrane components
Explanation:
Endoplasmic reticulum is a network of membranes fistulas; within the cytoplasm of a eukaryotic cells, where proteins and lipids are synthesized usually connected in continuum with the nuclear membrane of the cell.
The ER is of two kinds the smooth and the rough ER (Endoplasmic reticulum).
Functions of Rough endoplasmic reticulum includes; * Synthesis of protein * Degradation of worn out organelles
While the functions of Smooth endoplasmic reticulum includes; * Synthesis of lipid and steroids * Role cellular metabolism * Storage and metabolism of calcium * Catabolism of toxic substance.
Inference from the functions stated above shows that ER is actively involved in the synthesis of cellular membrane components.
