Which of the below statements is correct? Please choose the correct answer from the following choices, and then select the submi

Reil [10]

Answer: The correct answer is option D.

Explanation:

In diploid organism, chromosomes are present in pair. One chromosome is inherited from mother and one from father. The chromosomes pair is termed as homologous chromosomes. They are similar in shape, size, number of genes present, sequence of the genes, position of centromere, et cetere.

Thus, option A is incorrect.

However, the genes may have different allele. For example chromosome 1 (maternal) contains one dominant allele, say T, while chromosome 1 (paternal) contains recessive allele at the same locus, say t,.

So, if an organism contains same alleles for the trait then, it is termed as homozygous for that trait. It can either be homozygous dominant (TT) or homozygous recessive (tt).

Thus, option B and C are incorrect.

However, of an organism contains two different alleles for the trait then it is termed as heterozygous for that trait (Tt). The phenotype is usually resulted from the expression of dominant allele.

Hence, option D is the correct answer.

In the male reproductive system, the pituitary hormone _____ stimulates Leydig cells to secrete testosterone, and the pituitary

Katena32 [7]

Answer:

<u>Luteinizing hormone </u>(LH) stimulates Leydig cells to secrete testosterone

<u>Follicle stimulating hormone (FSH)</u> stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis

Explanation:

Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.

Explanation:

If you need extra resources: Lawn and garden chemicals, such as fertilizers enter the groundwater in two ways. In the first method, the chemicals can enter the groundwater by rainwater into a stream as runoff. This is especially problematic in urban environments where hard-surfaced roads allow rainwater to move over them without benefit of soil acting as a filter (Rosen and White, 1999). The water in streams replenishes groundwater, so the chemicals are absorbed into the groundwater as well. The second method of contamination is through leaching, which is the downward movement of a substance through the soil. The fertilizer may also dissolve into the surface water, which recharges the groundwater (Virginia Cooperative Extension, 1996). Nitrate is highly soluble and readily leaches into groundwater. Water with over 10 parts per million nitrate-nitrogen can cause methemoglobinemia, an inability to use oxygen in infants. The nutrient phosphorus harms clear, free water by creating algal blooms. This process, known as eutrophication, turns the water green, clouds the water, causes odor problems, and depletes the oxygen for fish and other species, effectively suffocating them (Lake Champlain Basin, 1998). To ensure that the groundwater does not get so contaminated as to be unhealthy, in 1986 the Department of Food and Markets implemented the Pesticide Monitoring Program. The goal of this program is to test wells in agricultural areas to help farmers learn about practices that prevent pesticides from leaching into the groundwater, and to conserve the nutrients in fertilizers and manure in the soil. This program is funded by fees taken from companies that sell pesticides and fertilizers in Vermont (Vermont Department of Agriculture, Food and Markets, 1998).
