The life cycle of a parasite occurs in various forms in all living hosts. The parasites must infect more <span>than one hosts to complete their life cycle. So it is very important to know how many hosts have these parasites taken over, because then they will know how much longer the parasite will survive and how to treat it. </span>

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.

During glycolysis, when glucose is catabolized to pyruvate, most of the energy of glucose is a. retained in the pyruvate. b. tra
Leona [35]

Answer:

a. retained in the pyruvate

Explanation:

Glycolysis is a cytoplasmic pathway that converts glucose into two pyruvate, releasing a modest amount of energy captured in two substrate-level phosphorylations and one oxidation reaction.

Following are the important enzymes in it :

  1. Hexokinase
  2. Phosphofructokinase
  3. Pyruvate kinase

Aerobic glycolysis yields 2ATP/glucose plus 2NADH/glucose but most of the energy is retained in pyruvate which is then converted into Acetyl-CoA and enters the kreb's cycle.

Chloramphenicol binds in the active site of the large ribosomal subunit and inhibits peptidyl transferase activity in the 23s rr
valentina_108 [34]
This inhibition is restricted to bacterial translation because; the peptidyl transferase is an enzyme aminoacyltransferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the process of translation. Therefore, inhibition of this enzyme means that the process oof translation wont take place, hence proteins will not be formed and thus the bacteria will die.

Field mice in beach mice are closely related species. The Field mice are various shades of brown in the beach mice or later 10 a
wariber [46]

Answer:

The process of natural selection is acting on <u>Field mouse individuals</u> where as evolution is occurring on <u>Field Mouse population. </u>

Explanation:

As the problem shows, the field mice are the ones that natural selection is acting on, but only the ligher shade ones. Because the lighter shade individuals are more likely to survive in the beach because they blend with the environment.

Evolution occurred on the field mouse population because if you read the script in the end, they were able to successfully reproduce. This means that they evolved in such a way that they were able to survive in their new environment. (most likely carrying on the trait of light-colored fur)

Natural selection acts on traits, phenotypic traits, favorable to the environment. Evolution occurred because of the natural selection, because the favored trait enabled the organism to adapt to the environment.
