Answer:
This situation might happen depending on the ecosystem that it takes place in.
Explanation:
For example, in one ecosystem, where there are no serious predators trying to get the coyotes, they could be in a higher level because there is no immediate danger to them. However, in another ecosystem where there are predators trying to hunt them, they would be in a lower level because there, they are not at the top of the food web. Basically, it all depends on the ecosystem.

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.
Answer:
Meiosis II.
Explanation:
Meiosis may be defined as a type of cell division in which four daughter haploid cells are produced from the single diploid cell. Meiosis is also known as reduction division as the chromosome number is reduced to half as compared with the original parent cell.
Meiosis is divided into meiosis I and meiosis II. The meiosis is similar to mitosis as the each cells contain only one set of the homologous chromosomes.
Thus, the correct answer is option (3).
