Answer:
The law of conservation of mass states no matter is created or destroyed. This means that the matter currently on Earth is the only matter that will ever be available to us. However, it also means that this matter will not be destroyed. So, water, oxygen, carbon, and nitrogen are all used by living things in our world and then recycled to be used again.
One example of this is the water cycle. More water is never added or taken from the world, it is just reused. First, water starts in some body of water and then evaporates into the air. Then, the water falls back to Earth as precipitation.
Answer:
e. is under purifying selection
Explanation:
Purifying selection removes deleterious alleles that can arise through
random mutations
.
Mutations may or may not have consequences at the level of genetic expression depending on whether those mutations are synonymous or nonsynonymous. Synonymous mutations do not generate changes in the protein to be encoded while non-synonymous ones do.
Important genes for the development of the organism - such as those involved in the neural development- are very likely to be under purifying selection, eliminating individuals with deleterious alleles since those alleles (product of non-synonymous substitutions) do not allow the individuals to survive.
The primary function of all lymph nodes is the production of lymphocytes, which help defend the body against microorganisms and against harmful foreign particles and debris from lymph before it is returned to the blood stream. The major clusters of lymph nodes are in six areas.
