I believe it is A because I know Nonpoint source pollution can include excess fertilizers, herbicides and insecticides from
Agricultural lands and residential areas. I hope it is right.. please let me know
The randomness in the alignment of recombined chromosomes at the metaphase plate, coupled with the crossing over events between nonsister chromatids, are responsible for much of the genetic variation in the offspring. To clarify this further, remember that the homologous chromosomes of a sexually reproducing organism are originally inherited as two separate sets, one from each parent. Using humans as an example, one set of 23 chromosomes is present in the egg donated by the mother. The father provides the other set of 23 chromosomes in the sperm that fertilizes the egg. Every cell of the multicellular offspring has copies of the original two sets of homologous chromosomes. In prophase I of meiosis, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up at the midway point between the two poles of the cell to form the metaphase plate. Because there is an equal chance that a microtubule fiber will encounter a maternally or paternally inherited chromosome, the arrangement of the tetrads at the metaphase plate is random. Thus, any maternally inherited chromosome may face either pole. Likewise, any paternally inherited chromosome may also face either pole. The orientation of each tetrad is independent of the orientation of the other 22 tetrads.
Explanation:
1) determine the probability of individuals inheriting a disease
2) In the future, new genetic mutations will arise, and knowing to understand genetics would be important in helping analyze the problem/mutation in genetic recombination.
3) Genetics allows us to link diseases to one another (pedigrees) by analyzing if they are recessive, dominant, and/or autosomal, this allows us, as scientists to be able to identify and classify future diseases, and to determine their inheritance pattern, in the future.
Answer:
It is a facultative anaerobic organism.
Explanation:
This organism makes ATP (energy provider molecule) by aerobic respiration in presence of oxygen, but when oxygen is removed it is capable of switching to fermentation (sugar consumption increases and growth rate decreases).
This happens because fermentation is much less effective at producing ATP and therefore there is not enough energy for growth.
This organisms are called facultative anaerobic.
Organisms with this type of metabolism include bacteria like Escherichia coli and Salmonella or yeast like Saccharomyces cerevisiae.

Can someone help me please Explanation:
Is this test the I going to have trace the path a red blood cell would follow starting in the right ventricle and back to the right ventricle included will be every structure ( heart chamber, valve, vessels ) that the red blood cell would pass trough???
