<u>Answer:</u>
The major type of weathering that takes place in a desert in Physical Weathering.
<u>Explanation: </u>
Physical weathering also known as mechanical weathering takes place in deserts. This weathering takes place due to physical or mechanical forces. Frost chattering, temperature fluctuation also causes physical weathering.
In the desert, there is a fluctuation in temperature. In deserts, the temperature during the day will be very high and at night the temperature will be very low. As a result, the rocks expand during daytime due to heating and at night the rocks undergo contraction due to the reduction in temperature. Hence the rocks are weakened followed by the disintegration or breaking of rock.
It takes the muscle time to act once it receives a response from the nerves. It also takes time for the electric impulse to pass between gaps in the nerves (synapses).<span />

61/3 is the answer for this question
The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.
Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.
Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.
