Plants perform cytokinesis differently than animals because plant cytokinesis takes place during interphase but animal cytokinesis takes place in cell division.
> Unlike animal cells, plant cells have a cell wall which needs to be divide or split up.<span>
>Mitosis and cytokinesis are two different things; mitosis is the division of the components of the nucleus, whereas cytokinesis is the division of the
cytoplasm and its constituents.
Thus, the answer is letter A.</span>
Levels of activity in the frontal lobe tend to be lower in the brains of people with schizophrenia than in other people.

One of the many tests that may be used to identify the presence of cyclohexanol in a product is that of the Lucas test.
The Lucas test is a chemical reactant test to determine the presence and level of alcoholism in a solution. Cyclohexanol has many chemical properties as do most substances, one of which is the presence of an alcohol group.
The presence of this chemical group makes it possible to test for cyclohexanol using the Lucas test. The Lucas test will cause reactions in the presence of alcohol and transform alcohols into chloroalkanes, which tend to be nearly insoluble in aquatic solutions. Given this, a <u>positive result </u>will look like <em><u>the solution separates into a cloudy chloroalkane-containing part on top of a much clearer layer.</u></em>

Answer: The correct answer is-
an agent that causes a mutation in DNA.
Mutagen is an agent or a substance that causes permanent change in the genetic material of living organisms ( DNA, deoxyribonucleic acid). This process is called mutation.
A mutagen can be a chemical, physical or biological agent that causes mutation in the DNA.
Example- Physical agents such as -
- Ionizing radiations like alpha particles, gamma rays, X-rays that brings break in the DNA and cause other damages.
- Ultraviolet radiations that creates pyrimidine dimers ( T=T) and causes replication errors if damage is not repaired.
Primary eats grass and plants and the secondary eats the primary to get the energy it needs to live
