The purpose of spindle fiber is to divide the chromosomes in a parental cell to make them into two daughter cells.
Answer:
The correct answer is A they will no longer be able to perform aerobic respiration.
Explanation:
Rotenone is an isoflavonid compound which act an inhibitor of electron transport chain in mitochondria.Rotenone generally blocks the transfer of electrons from from NADH CoQ dehydrogenase or complex 1 to ubiquinone.
As electron transport is blocked the reduced coenzymes such as NADH,FADH2 are unable to be oxidized.
As a result cells exposed to rotenone will no longer be able to perform aerobic respiration.
Answer:
When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
Explanation:
Explanation:
you can see that one out of four offspring (25 percent) has the genotype PP, one out of four (25 percent) has the genotype pp, and two out of four (50 percent) have the genotype Pp. These percentages of genotypes are what you would expect in any cross between two heterozygous parents.
There is a lot of competition. From food, water, shelter, mates... only the best, the organisms with the desirable traits survive. They survive and are able to reproduce, passing on their genes to the next generation. As this natural selection occurs, the traits that are necessary for survival are passed on, and over a long period of time this results in evolution.
