The S phase is critical in the cell cycle because it indicates the cell is ready for division.
Individuals adapt to their environments and, thereby, evolve
Explanation:
Natural selection is the main process which advances evolution by aiding organisms to survive and produce more offspring through adapting more to their environment. Mutations, gene transfer, and genetic variations also drive evolution.
Both natural selection and evolution work on genetic behaviors in populations rather than individuals. Both natural selection and evolution are involved in generating changes over generations. Examples of evolution is the disappearing of tail bone, decreased head size and for natural selection example is the long and short necked giraffe.
The correct answer is the immune system, more specifically, the thymus gland. The thymus gland, while it produces hormones like thymosin, it is more closely related to the immune system rather than the endocrine system. This is because lymphocytes that go into the thymus gland mature into T lymphocytes that can either be a helper T cell or a cytotoxic T cell, depending on the stimulus.
A logo advertising the importance of genetic diversity would be "Varied progeny to mask nature's agony"
Explanation:
Genetic variation is an important aspect of maintaining a population. The valuable alleles of the gene which can resist diseases, pests and adaptation to the environment. In natural selection, we have seen only those organisms are likely to survive who produces more offspring, passed on useful traits to adapt to the environment. Those organisms will eventually evolve.
At the time of environmental change, the organism with a large population and adaptability will survive.

Answer: B. global warming</h3>
As more CO2 (carbon dioxide) is released into the atmosphere, it traps more heat energy from the sun, and slowly warms the average temperature of the earth. This is the simplified version of what global warming is. Carbon dioxide is considered a greenhouse gas.
