The plasma membrane is a semi-permeable membrane that allows the movement of a molecule from inside to outside of the cell and vice versa.
Further Explanation:
The plasma membrane is mainly composed of cholesterol, protein, and phospholipids. They move easily in the membrane and maintain the fluid nature of a membrane. The main component of the plasma membrane is phospholipids that are made up of fatty acid, phosphate, and glycerol. These phospholipids make two layers of phospholipids that are mainly known as the lipid bilayer. This bilayer makes the plasma membrane semi-permeable and helps in the transport of molecules from inside to outside and vice versa.
Other components of the lipid bilayer are carbohydrates and protein. They also play a major role in the plasma membrane because they help in cell signaling. Glycolipids are present on the outer side of the cell membrane. The membrane of the cell also plays a significant role in protecting the cell from the exterior environment and acts as a barrier.

Answer:
Translation may be defined as the formation of the protein product from the RNA molecule. Different enzymes and proteins are required for the process of translation. Translation involves three steps - initiation, elongation and termination.
The testosterone hormone in humans helps in the development of the male secondary sexual characters. The testosterone hormone binds with the proteins and then protein binds to the specific DNA sites. These proteins helps in the transcription of the certain genes and may acts as the enhancers.
Answer: The given statement is False.
Repositories for the radioactive waste disposal are the the burial facilities, which are excavated in higher depth ( approximately 1000 feet below) having stable geologic environmental conditions.
They are used for burying radioactive waste so as to avoid the exposure of human population and environment with radioactive material ( which could be hazardous to lives as well as environment) present in the waste.
They could be built in any area that is geologically suitable for burying waste. This means that they have no relation with the size of population in that area.
Thus, the given statement is False.
False you can find them anywhere.
b. to carry the synthesized genetic information from the nucleus to the ribosomes
c. to synthesize proteins from RNA
d. to bring amino acids to the ribosomes to be assembled into proteins
to bring amino acids to the ribosomes to be assembled into proteins
Answer:
In primary succession, newly exposed materials are growing and colonizing the area for the first time, while in secondary succession, it is an area that was previously occupied by organisms, but was then disturbed, then recolonized again.
Answer: A. The same policies and concerns about the use of human embryonic stem cells would most likely apply.
