If a mutation occurs in the genes of reproductive cells (gametes) that mutation is termed a germinal mutation. <span>Germinal mutations usually are not expressed in the individual containing the mutation, but gametes that carry the mutation will pass it on to the offspring. So, we say that the germinal mutations are hereditary mutations, inherited from a parent and present in every somatic and germline cell in the offspring.</span>
Answer:
- Dependent variable: number of cells that are in one of the phases of mitosis
Explanation:
In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
An animal cell that is placed in a hypotonic solution will rapidly gain water, because osmosis would cause the water to move to an area with more solutes. In this case, that is the inside of the cell. A cell in a hypotonic solution may gain enough water to lyse, or rupture, the cell membrane, which destroys the cell.
The first one with the boxing crab and anemone is mutualism.
The second one with the dog and flea is parasitism.
