Answer:
2. meiosis I only
Explanation:
During the zygotene stage of prophase-I of meiosis-I, homologous chromosomes synapse and are paired up. These paired homologous chromosomes are called bivalents. These paired homologous chromosomes align themselves at the equatorial plate of the cell during metaphase-I. Therefore, when observed through a microscope, cells are shown lined up two by two. During meiosis-II and mitosis, individual chromosomes with two sister chromatids are aligned at the cell's equator in metaphase.
Answer:
The correct answer is option (D) "His- strain grows on an his- plate".
Explanation:
The Ames test is a procedure that allows to detect if a given compound can cause mutations on a tested organism by growing strains of bacteria that require histidine (His-) to growth, since they are not able to produce its own histidine. In the Ames test, the bacteria is exposed to a given compound and is grown in a medium with small amount of histidine (his- plate). If the His- strain grows on a his- plate, it means that the bacteria has mutated to synthesize its own histidine and it is considered as a positive result on a the Ames test.

On land but close to oceans. Thus, option "A" is correct.
<h3>What is an earthquake?</h3>
Earthquakes occur as a result of collisions along oceanic-continental convergent boundaries.
The majority of the earthquakes occur alongside the Ring of Fire of the Pacific Ocean. The Ring of Fire is found in the basin which is a land area found close to the coastlines of the ocean. This validates its occurrence on land but close to the oceans.
Thus, option "A" is correct.
