Answer:
When oxygen levels in the blood decrease, the respiratory center sends signals to the diaphragm to increase the rate at which it contracts and relaxes.
Explanation:
Answer:
B
Explanation:
This macromolecule is DNA. Its stored genetic information in form of genes that translate to functional or structural proteins that make up an organism. The DNA double helix is unzipped by helicases enzymes into single strands. RNA polymerase transcribes the single strands into mRNA. The mRNA is then translated into proteins by ribosomes. This is called the central dogma (DNA RNA Proteins).
During cell division, the DNA is replicated into two copies and each copy goes to each of the two daughter cells preserving, more or less, the same genetic code to the new cells.
<span>It have 18
chromosomes in its eggs. Because it has 6 chromosomes in each somatic cells. So
6 x 3 = 18 chromosomes. This is because the mosquito received 3 chromosomes
from its mother and 3 chromosomes also from its father making up 6 chromosomes.</span>
6:1 Ratio means that it is easier to move the materials. SA = ^2, while V = ^3. That means volume increases at a faster rate than surface area. That is why is it optimal to have a high SA:V ratio, which is why cells are so small.
