Answer:
<h2>True</h2>
Explanation:
1 .Reverse transcriptase (RT) is an RNA-dependent DNA polymerase enzyme which makes DNA from RNA..
2. RT makes double-stranded DNA molecules from ssRNA ( single stranded RNA) molecule using it as a template.
3. Retroviruses like HIV contain Reverse transcpritase (RT) enzyme, which uses the RNA molecule as template and make DNA from it and after that, virus make multiple copies of itself.
4. Reverse transcriptase enzyme make DNA reverse transcrptionally from RNA the process known as RNA dependent DNA polymerase.
5. It was first discovered in retroviruses.
Small bone fractures that develop in response to repetitive, cumulative trauma are known as stress fractures. These are fractures where bones are injured by overuse, they are commonly found in the spine, vertebrae, leg bones, feet, and the pelvis. They result from the accumulated trauma from repeated submaximal loading, such as running or jumping
Answer:
A. Each half of the chromosome is genetically identical.
Answer:
Explanation:
Natural selection is based on Darwin’s observation that individuals most likely to survive and reproduce are those with traits best suited to their current environment.
The increase of carbon dioxide in the atmosphere creates a greenhouse effect.
To explain this usually some sunlight is reflected back into space while some is absorbed by the earth keeping the planet warm. However the increase in greenhouse gases such as carbon dioxide prevent the light from reflecting back into space and this light becomes trapped causing the earth to heat more then it should. You can almost think of the trapped heat from the greenhouse gases as a blanket around the earth trapping the heat in.
