Body cells are those that are responsible for the formation of tissues and organs, while a gamete is that cell responsible for reproduction.
- Gametes are sex cells, when a male gamete joins a female gamete in the framework of sexual reproduction of plants and animals, a zygote is formed.
- Body cells are any cell in the body that are not gametes, which originate from embryonic stem cells and constitute the totality of the body's tissues and organs of multicellular organisms.
Therefore, we can conclude that body cells are those cells responsible for the growth of organs and tissues and gametes are each of the sex cells that fuse during fertilization.

Answer:
Explanation:
Bacterial count in stock- 1.85x10^6 cfu/ml
Dilution methods
Take 100 uL or (0.1ml) from stock and add to 900ul (0.9ml) saline and mixed it- this makes 10^1dilution.
Now take 100ul from 10^1 dilution and add to next 900ul saline this is 10^2 dilution, similarly do upto 10^5 dilution.
Then take 100ul from 10^ 4 and 10^5 dilution seperately and plate on LB agar plate seperetely and count the colonies.
Cfu/ml formula= (No.of colonies x dilution factor)/0.1 ml
So suppose, 18 colonies formed on 10^4 dilution then total no. Of cells in stock will be 18x10^4/ 0.1= 18x10^5 cfu/ml.
If we dilute 10^4 or 10^5 that's leads to colony count of 18-19 colonies on 10^4 dilution while 2 colonies should come on plate of 10^5 dilution.
<h3><u>Answer;</u></h3>
b). Activation of an upstream guanine nucleotide exchange factor
<h3><u>Explanation</u>;</h3>
- <em><u>When a ligand activates the G protein-coupled receptor, it induces a conformational change in the receptor that allows the receptor to function as a guanine nucleotide exchange factor (GEF) that exchanges GDP for GTPthus turning the G protein-coupled receptor on.</u></em>
- The activated G-protein then dissociates into an alpha (G-alpha) and a beta-gamma complex.
Glucose is required for both aerobic and anaerobic respiration.
Mutualism is where both animal help each other to benefit form each other. Win-Win . Commensalism is where nothing happen neither animal benefits from it .
