1. Although generally not considered to be alive, a is studied alongside other microbes such as bacteria2. The protein coat that surrounds the nucleic acid of a virus3. A viral life cycle that results in bursting of the host cell4. A viral life cycle in which the virus inserts its genome into the genome of its host, where it may remain dormant for long periods.5. Viral genome that has inserted itself into the genome of its host

The correct terms are as - 1. virus, 2. capsid, 3. lytic cycle, 4. lysogenic cycle, 5. prophage.

Explanation:

A virus is considered as nonliving by various scientists as it required a living host to divide, however, it is studied with the microbes such as the bacteria and others. The virus is made up of nucleic acid surrounded by the protein coat called a capsid.

Viruses normally show two types of life cycles inside the host cell that are the lysogenic cycle and the lytic cycle.

The lytic cycle is characterized as the life cycle that ends with the destruction or bursting of the host cell. The lysogenic cycle includes being dormant inside the host genome until the favorable condition reestablished. Prophage is a virus that inserts itself into the host genome on its own.

Thus, the correct answer is - 1. virus, 2. capsid, 3. lytic cycle, 4. lysogenic cycle, 5. prophage.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

the denominator has a very specific role.
