Answer: gravity and an environmental factor
Explanation:
Answer:
Plasmolysis occurs when a <u>plant </u>cell is inmersed in a <u>3X salt solution</u>.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
- <em>Plamolysis does not occur in </em><u><em>animal cells</em></u><em>.
</em>
- <u><em>Pure water </em></u><em>does not produce plasmolysis.</em>
Replication is the process where DNA molecules copies itself to form another DNA molecule during cell division. it involves several enzymes which includes DNA helicase, the enzyme that unwounds the DNA double helix. RNA primase, it is an enzyme that creates an RNA primer. DNA polymerase, it is the enzyme that matches and lays down nucleotides to form the new DNA daughter. DNA ligase joins the Okazaki fragments by catalysing the formation of phosphodiester bond.
