I think its B. It sounds familiar
Answer:
For the 1st part, the correct answer is option C.
In a polymerase chain reaction, the amplification of DNA template takes place not RNA. So, prior to going into the process, there is a need to initially convert RNA into DNA with the help of an enzyme reverse transcriptase.
For the 2nd part, the correct answer is option D.
The suitable temperature for human DNA polymerase is 37 degrees Celsius, and it gets denatured at greater temperatures. As PCR runs at exceedingly high temperature like 95 degrees Celsius, only Taq DNA polymerase can withstand the temperature. Thus, normal DNA polymerase cannot be utilized in the PCR reactions.
<span>The picnic blanket is equals to 1 meter
an ant length is equals to 1 centimeter
now, let’s find the number of ants in total in order to fit end to end across
the length of the picnic blanket.
1 centimeter is equals to 0.01 meters. And in 1 meter there is a total of 100
centimeter
=> 0.01m x 100 = 100cm
Therefore, it needs a total of 100 ants that measures 1cm each in order to fill
the blanket that measures 1m from end to end.

Answer:
There are two structurally and funtionally different surfaces in epithelial tissue.
Explanation:
The outer covering of organs and blood vessels is lined by epithelial cells. These cells also line the inner surface of many cavities in the body.
- Glands are formed of epithelial tissue and divided how they secrete their hormones (Exocrine and Endocrine gland).
- The cells in epithelial tissue are tightly packed.
- One side of cells is free that is not in contact with other cells (outer covering).
