The answer is <span>c. Living organisms modify their environment a little at a time.</span>
The purpose of succession is for an ecosystem to reach balance state right after it is formed or after it is disturbed by man or some disasters. It will increase biodiversity and help to prevent the desertification. Living organisms modify environment a little at a time. By modifying it, they make the environment more suitable for the new species to enter the community.
Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.
During meiosis, chromosome pairs randomly line up along each side of the cell equator. This arrangement mixes up the chromosomal combinations, which
A. helps ensure reproductive success.
B. helps create and maintain genetic diversity.
C. helps maintain all of the previous generation's characteristics.
D. helps ensure an equal number of males and females in the next generation.
