Answer:
Simply by the changing of the DNA.
Explanation:
Meiosis is the process where a cell with 2n chromosomes divide to produce 4 new cells with n number of chromosomes each with different genotypes which is how single-celled organisms reproduce and reproductive cells divide. This creates different genetic combinations therefore supporting diversity and natural selection.
Crossing Over is a procedure that is a part of the meiosis. It is when the chromosomes are replicated and at a total of 4n, the homologous pairs of the chromosomes have a cross-over of DNA, resulting in genetic diversity.
Mutations, even though they are harmful most of the time, are also a process where genetic diversion accours because of either mistakes in the cell divisons or external effects such as radiation. Therefore mutations are also contributing to the allele diversity.

it is C. Shallow roots, for those using edginuity just took the test
A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
