Answer:
The role that white blood cells play is to destroy bacteria.
Explanation:
They destroy them to keep you healthy and to keep u alive. They destroy the virus by eating it away. For example, when u get a flu shot, bacteria is flowing into your system but its not that strong. This prepares your white blood cells for the actual flu. It makes your body stronger, and more resistant.
Answer:
Messenger RNA on the ribosomes binds amino acids into a peptide chain called a preprohormone. the chain is directed into the ER lumen by a signal sequence of amino acids
-enzymes in the ER chop off the signal sequence, creating an inactive prohormone
-the prohormone passes from the ER through Golgi
-secretory vesicles containing enzymes and prohormone bud off the golgi. the enzymes chop the prohormone into one or more active peptides
-vesicle releases contents by exocytosis
-hormone moves into circulation for transport to its target
<h2>The answer is RNA</h2>
Answer:
The correct answer is C) ensures the continued existence of the human species.
Explanation:
The human reproductive system is responsible for the production, storage, and transfer of gametes to the next generation. In the male reproductive system, testes make gametes and in the female reproductive system, ovary makes gametes.
The reproductive system in humans ensures the continued existence of human species in this world because the reproductive system is responsible for gamete fusion and new offspring developments which are more adapted in the environment. This ensures the existence of humans on earth.
If you look at Cosmos episode 1, I'm sure you find an answer there.
Tetraploidy will occur.
<h3><u>Explanation</u>:</h3>
The process of sexual reproduction is very necessary to maintain the genetic setup of the species over the races.
The normal chromosome content of a cell is called diploid state of cell. Its represented by the expression 2n. The cell division that takes place before the gamete formation is called meiosis. This cell division makes the chromosome number of the cells halved. So haploid cells are produced. Its represented by n.
Now as the gametes fuse, both the n becomes 2n and diploid state is regained.
But if the meiosis don't occur in the gametes, the gametes will remain 2n. So after fertilization, it becomes 4n. This state is called tetraploidy.
