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.
<span>Scientist think convection currents are what cause earths plates to move. a convetion current is caused by the diffrence in the temperature, Mantle material close to the earths core is very hot. Mantle material near the lithosphere is cooler.</span>

Answer:
True
Explanation:
Ans;true
The neural plate is one of the features exclusive to the embryonic development of chordates. It is located dorsally to the notochord. The neural plate is the rudimentary nervous system of the embryo. During early development ,the neural plate is formed from the ectodermal layer . It undergoes changes in the position and arrangement of it's cells to form the brain and the spinal cord which comprises the central nervous system. It forms tissues and eventually organs by the deepening of the groove which forms ridges which eventually folds and fuses to form the neural tube . The tube differentiates into the prosencephalon, the mesencephalon and the rhombencephalon, from which the organs are formed
There numerous of them but some of them would be contaminated soil which can be followed with altered soil chemistry that contains fewer soil organisms that are essential. The third one would be surface runoff due to extensively modified hydrology of the area.
