1. C
2. B
Explanation:
1. When a plant cell looses some water due to dehydration or being placed in a hypertonic solution, the term used to describe the cell's intial, not severe shrinkage is 'flaccid'.
Here, it's clear that the cell shrank so much that the cell membrane pulled away from the cell wall. The correct term for this severe shrinkage is 'plasmolysed'.
We don't use 'wilted' as a term to describe a cell. We use it to describe the plant as a whole.
2. This is the function of each. Water and ions in xylem and sugars like sucrose in phloem.

Cell division involves the different phases such as G1, G2, M and S phase. Cell division is the mechanism of cells to divide into other cells. Two types of cell division is popularly called the mitosis and meiosis. There basic difference is how they function and how many chromosomes their daughter cells have.
Mitosis is the cell division that happens anywhere in the body for most cells. However, the meiosis happens in the production of gametes are the reason why there are only 23 chromosomes in the sperm and egg cell.

Stimulated by the action of the ions on its receptors, the pump transports them in opposite directions against their concentration gradients. ... The sodium-potassium pump carries out a form of active transport—that is, its pumping of ions against their gradients requires the addition of energy from an outside source.
Answer:
The correct answer is option D. they were part of the control group.
Explanation:
A control group is a group of subjects different from the other test subject as they did not get the independent variable's effect on them and separated from the rest of the experiment. This group of subjects is used to rule out any other explanation of the effect of the independent variable.
In this experiment, subjects that received a placebo injection are the control group as they did not expose to the mutated virus and there are the presence of antibodies in the blood.
Cytosine. This is because Guanine ALWAYS bonds with Cytosine in DNA
