Endoplasmic reticulum serves as transpiration area. The correct option is B.
<h3>What is endoplasmic reticulum?</h3>
The endoplasmic reticulum (ER) is a large, dynamic structure in the cell that performs numerous functions such as calcium storage, protein synthesis, and lipid metabolism.
The ER's various functions are carried out by distinct domains, which include tubules, sheets, and the nuclear envelope.
The endoplasmic reticulum can be smooth or rough, and its function is generally to produce proteins that allow the rest of the cell to function.
Ribosomes, which are small, round organelles that make proteins, are found in the rough endoplasmic reticulum.
Thus, the correct option is B.

Answer:
A- A pH change can cause the enzyme to change its shape
Explanation:
A rise or fall in the pH of the medium from the optimum of pH 7 usually affect the enzymes' active sites of and therefore the shape and the rate of enzyme activity.
Assuming the pH is too low, the enzyme medium becomes acidic;Acidosis. The high Hydrogen ions concentration interacts with the R-groups of the amino acids moiety of the enzymes, this interaction affects the ionization of the R-groups, disrupting the ionic bonding holding these R-groups in shape.
This results in loss of the 3-Dimensional shape arrangements of the protein molecule and therefore of the active sites. Since active sites of enzymes determines the specificity of the <u>enzymes substrate- complex </u> to give <u>enzyme-product complex,</u> the catalytic activity of the enzymes decreases, <u>the rate of reaction decreases,and products formation stops, and the reaction also stops.</u>
The same is applicable to extremely high pH=Alkalosis.
However, the effective buffer system of the body prevents this scenarios from happening in real sense in the body. Through mopping by the haemoglobin, excretion by the kidney, etc
Answer: Leu (leucine)
Explanation: The mRNA code for a DNA strand of AAT is UUA. The amino acid that UUA codes for is Leu, short for leucine (I don't know if you need the full name of it).
<span>Antibiotic resistance arises due to the evolution of the organisms they are designed to destroy. Subsequent generations of such organisms develop resistance to the antibiotic. Hospitals' overuse of antibiotics quickens the process, as does the administration of antibiotics to feedlot cattle, whose meat is consumed by people.</span>
