Answer: A. lipids.

Explanation:

Cutin: This is a long-chain fatty acid polymer, that enters the spaces between the cellulose microfibrils of the epidermal cell wall, making her cutinized. It is later deposited externally and together with the wax forms the cuticle. The cuticle helps to restrict sweating; being bright helps to reflect the excess of solar radiation and being a substance that is not digested by living beings, it also acts as a layer, protecting against the action of fungi and bacteria. Cuticle formation begins in the early stage of organ growth.

What are two substances that may be formed in anaerobic respiration?

Again the only ATP that is produced occurs during the glycolysis reactions. One three-carbon molecule (pyruvic acid) is changed into another three-carbon molecule (lactic acid) and no carbon dioxide is produced like during other forms of respiration.

In plants tall (T) is dominant to short (t) and round seed is dominant to wrinkled seeds (r). If a parent is short and wrinkled

Nuetrik [128]

Answer:

Parent cross= ttrr (short, wrinkled) × TtRr (hybrid)

POSSIBLE GAMETES BY EACH PARENT:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

Explanation:

This question involves two genes in a certain plant. One gene is coding for height while the other is coding for seed shape. The alleles for tallness (T) and round seeds (R) is dominant over the alleles for shortness (t) and wrinkled seeds (r).

According to this question, a parent that is short and wrinkled (ttrr) is crossed with another parent that is hybrid (TtRr) for both traits. This means that the parent cross is as follows: ttrr × TtRr

The possible combination of gametes that will be produced by each parent is as follows:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

See attached image for the punnet square using these gametes.

Lynna [10]

The question is incomplete as it does not have the options which are:

A. bioremediation

B. mutualism

C. quorum sensing

D. quorum settling

E. mass-settling

Answer:

C. quorum sensing

Explanation:

Quorum sensing is the gene regulation mechanism used by the bacteria to communicate with the other bacteria. The quorum sensing process depends on the number of bacterial cells or the density of the cells.

When the bacterial number increase in number then the bacterial cells send the signal to the nearby cells and and regulates the expression of the gene. In the given question, the same chemical signal process depends on the density of the cell and thus quorum sensing is correct.
