Answer:

A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA.

BlackZzzverrR [31]

Answer:

Freshwater wetland biome

Explanation:

Wetlands are defined as those areas where the land area is mostly covered by water seasonally or annually. The areas remain wet. Freshwater wetlands are a type of biome that is not connected to the ocean. They are found mainly along the boundaries of rivers, streams, and lakes. The water in the freshwater wetland is generally evaporated during the summer season.

This biome is highly rich in nutrients that provide a favorable site for the existence of numerous plants and animal species. The leaves that are detached from the trees are deposited within the soils and also captures and accumulates the organic materials that are eliminated from the large trees within this region.

Which fossil occurs on the most landmasses what does this suggest about when the continents broke up
Zepler [3.9K]

Answer:

Glossopteris and Lystrosaurus

Explanation:

Glossopteris is an ancient plant flora and Lystrosaurus is a fossil fauna, and both are found in many of the landmasses on earth. The Glossopteris flora appeared about 300 to 200 million years back and the Lystrosaurus appeared about 250 million years back on earth. They both existed from the time of late Permian to early Triassic age.

Both these fossils played an important role in understanding the continental drift theory or the plate tectonic theory. This evidence enabled geologists to understand how the continents have moved across the large ocean basin from one place to another and at what rate they are drifting currently. It helped in understanding how the super-continent Pangaea had broken into Laurasia and Gondwanaland, and further broken into the present location of the plates.
