Answer:
The correct answer is option D, that is, the elephant will not react.
Explanation:
A kind of behavior that comprises a stimulus-response, which is distinct from the natural one is termed as conditioning. It is a kind of learned behavior. It is a kind of learning where the efficacy of stimulus enhances while provoking a response. When the presentation of two stimuli is done at a suitable time and with appropriate intensity, then one of them will be able to provoke a response that resembles the other one.
In the given case, the mouse and the trombone are termed as unconditioned and conditioned stimuli. When a conditioned stimulus is demonstrated in a context of classical conditioning, it will result in the non-predication of the coming unconditioned stimulus. The conditioned response will get to cease slowly and will eliminate the conditioned fear. Thus, in the given case, the elephant will fail to react towards the trombone subsequently.
The development of the human embryo follows fertilization, and continues as fetal development. By the end of the tenth week of gestational age the embryo has acquired its basic form and is referred to as a fetus. The next period is that of fetal development where many organs become fully developed.

Answer:
Methotrexate inhibits the synthesis of DNA, RNA, and protein synthesis of the cells in the experiment.
Explanation:
Methotrexate competitively inhibits the enzyme dihydrofolate reductase (DHFR) which is involved in the synthesis of tetrahydrofolate from the inactive dihydrofolate. The methotrexate blocks the enzyme by binding to its active site thereby preventing further reaction of the dihydrofolate reductase enzyme and dihydrofolate. Tetrahydrofolate is a useful material for the de novo synthesis of thymidine, a nucleoside. And without thymidine, DNA synthesis is hindered. Methotrexate therefore inhibits the synthesis of DNA, RNA, thymidylates and of course protein synthesis.
