Answer:
Answer is hypodermis .
Explanation:
The hypodermis which is also known as the subcutaneous tissue layer, is found lying beneath the dermis and act as a passageway or channel through which blood vessels and nerves passed. It is made up of fat and connective tissues.
It acts as an insulator, this, help in keeping the body temperature stable.
Answer:
Because melting can be reversed ( freezing )
Explanation:
Physical change is a change that can be reversed
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.
The appropriate answer would be e. sub tropical desert. Arid and semi-arid regions get very little rainfall per year. The plants in theses regions must have special adaptations to reduce water loss or to live in dry areas. These plants have very small leaves to reduce water loss through transpiration. Some, such as cactus have evolved to loose leaves altogether. They instead have thorns. <span />
