Answer:
b. completely by mitosis
Explanation:
Mitosis is a process of cell duplication in which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
Carrying capacity refers to the maximum abundance of a species<span> that can be sustained within a given area of </span>habitat<span>. When an ideal population is at equilibrium with the carrying capacity of its environment, the </span>birth<span> and death rates are equal, and size of the population does not change. Populations larger than the carrying capacity are not sustainable, and will degrade their habitat. In nature, however, neither carrying capacity or populations are ideal—both vary over </span>time<span> for reasons that may be complex, and in ways that may be difficult to predict. Nevertheless, the notion of carrying capacity is very useful because it highlights the ecological fact that, for all species, there are environmental limitations to the sizes of populations that can be sustained.</span><span>

Answer: Glucocorticoids such as cortisol affect carbohydrate, fat, and protein metabolism, and have anti-inflammatory, immunosuppressive, anti-proliferative, and vasoconstrictive effects.
Answer:False
Explanation:
Acid rain is an indirect result of burning fossil fuels Acid rain occurs when sulfur dioxide and nitrogen dioxide are released into the atmosphere due to incomplete combustion of fossil fuels. Each of these oxides is mixed with rainwater to form sulfuric acid and nitric acid. Thus, acid rain is in fact an indirect result and is not a direct result of the release of acid when burning fossil fuels. This is because oxides are formed during combustion.
