In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.
Answer:
Amino acids are the building blocks of proteins
There are many possibilities that could happen if the sequence of amino acids were to change. It could potentially create a completely different protein with a different function, or it could create a more efficient protein but this is less likely.
Explanation:
<h2>Koch's Postulates.</h2>
Explanation:
The next step should be isolate the microorganism from the mice and check if it is identical to the original microbe.
According to Koch's postulates, a microbe can be considered as a causative agent of a disease only after all the following are established:
- The microorganism should be present in all the organism suffering from the disease.
- The isolated microorganism should be grown in pure culture.
- The organism grown in the culture should be reintroduced in the susceptible but healthy host.
- Finally the microorganism must be re-isolated from the experimental host an cultured to see whether it is identical to the original specific microorganism.
The answer is both in males and females; only in males. Males
have one Y chromosome and one X chromosome, while females
have two X chromosomes. In mammals, the Y chromosome controls a
gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and
other mammals also contain other genes needed for normal sperm production.
