Answer:

B. DNA replication and DNA transcription

Explanation:

Nucleus is the double membrane bound organelle present in eukaryotic cells. It is the site where DNA is present in these cells.

DNA replication is the process of formation of new DNA strands using the existing ones as a template. It occurs in the nucleus only.

DNA transcription is the process of formation of RNA using a DNA template strand. Since DNA is present in the nucleus only, DNA transcription also occurs in the nucleus.

In a sample of double-stranded DNA, 10 percent of the nitrogenous bases are guanine (G). What percentage of the nitrogenous base
DanielleElmas [232]

Answer:

40%

Explanation:

Remember that guanine always pairs with cytosine, and thymine always pairs with adenine. That means that any time there is a guanine, there is always a cytosine.

If there are 10% guanines, then there are 10% cytosines. That means the total of guanines and cytosines is 20%.

The other 2 bases (thymine and adenine) have to make up the rest of the bases. That means they have to make up 100-20 = 80%.

Again, there will be equal amounts of thymine and adenine, so 80%/2 = 40%.

aleksley [76]

Answer:

c. immune functions.

Explanation:

The endocrine system is involved in the regulation of metabolic rate, body temperature (thermoregulation), tissue development and labor contractions except immune functions.

Studies have shown that no hormone has been identified as being important in the regulation of the immune system. Therefore immune functions is not a regulatory function of the endocrine system.

Although, there have been articles on the endocrine and immune system crosstalk, only a hypothesis of various proteohormones not single hormones have been discovered to act on immunocompetent cells.
