I believe the correct answer is A
Answer:
well with out it we won't understand dna
but heres the scientific answer
Explanation:
DNA replication allows for organisms to be reproduced from the parent.
After a sperm (from male) and egg (from female) cell have combined, they immediately start to divide. At this point, the cell is called a zygote.
In order for the cells to divide, they need DNA from the mother. They don't steal it. They just replicate it. For a cell to use DNA, it needs to be in the form of a chromosome, a tightly-packed DNA structure
DNA replication allows for organisms to be reproduced from the parent.
The answer would be:
Cilium
<u>Here is more about the structures of prokaryotic cells:</u>
Axial filament is a bundle of flagella that are wrapped around the cell's body.
Flagellum is what the prokaryotic cell has that is whip-like in structure. It helps with the motility of the cell.
Pilus is a hair-like structure that are found on the surface of prokaryotic cells. They help the cell attach itself to surfaces.
Peritrichous flagella are several flagella that can be found all over some prokaryotic cells.
Answer:
autonomic nervous system (ANS)
Explanation:
The Autonomic Nervous System (SNA) is the part of the nervous system that controls and regulates internal organs such as the heart, stomach and intestines, without the need for conscious effort by the body. It is part of the peripheral nervous system (which includes the Somatic Nervous System or SNS and SNA) and for this reason it also controls some of the body's muscles.
Thus, most organs are controlled by the sympathetic and parasympathetic nervous system. Sometimes both have opposite effects on the same organ. For example, the sympathetic system increases blood pressure while the parasympathetic system decreases it. In general, both systems work together to ensure that the body responds adequately to different situations.
