Answer: Cell membrane has many properties which is stated below.
Explanation:
The cell membrane allow one cell to communicate with other cell. It is the cell membrane which is directly in contact with the cell membrane of the another cell.
The cell membrane also serves as a channel for the transport of materials from the outside to inside and vice versa.
It also provides stability to the cell. It combines with the carbohydrates and provides immune response and cell recognition.
<u>Answer:</u>
Effects Include:
Activates secondary messengers such as cAMP which further activates number of hormones like
- ADH: production of this hormone causes kidneys to retain more water inside body.
- GHRH: release growth factors and stimulates growth of organism.
- ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
- TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
- LH: Stimulate follicle maturation and formation of ovules in women.
- Calcitonin: Decreases blood calcium level by deposition calcium in bones. This effect weakens the muscles.
- Glucagon: Stimulates glycogen breakdown from liver and muscles and many more effects.
<u>Explanation:</u>
Background Knowledge:
GPCR (G Protien coupled receptors) are present inside plasma membrane in huge amount. As name suggest that these receptors are coupled with G proteins during their inactive state present inside of the cell. During their Inactive state these G proteins are bounded with GDP molecule.
Upon receiving signal molecules from outside of cell alters the shape of GPCR. These receptors also triggers change in G Protein, as a result of this GTP get attached with them. This protein further activates reaction cascades inside of the cell.
What happen if GTP cannot be hydrolyzed to GDP + Pi?
If GTP cannot hydrolyzed in to GDP + Pi than, it cannot be able to dissociate from G proteins. Cascade system doesn't stop and produces many effects on body.

Answer:
B. There will be two cells each with 36 chromosomes.
Explanation:
The products of mitosis are called diploid cells, and they each have the complete set of chromosomes. These cells are usually important for activities such as growth, repair etc. They make up our normal body (somatic) cells. Therefore, the answer is 36, only 36 matches the description of genetically identical cells
The correct option is C.
Science is a dynamic subject and it changes all the time. In the science field, research is always on going and when new evidence are discovered about a particular topic, the new evidence are usually used to update the scientific information that is already on ground. All the areas of science listed about have enjoyed scientific updates in the recent past.
Answer:
Nucleus
Explanation:
The Nucleus acts as the "brain" of the cell, working to store and replicate DNA.
