Answer:
<em>the</em><em> </em><em>example</em><em> </em><em>of</em><em> </em><em>prokary</em><em>otic</em><em> </em><em>organism</em><em> </em><em>is</em><em> </em><em>bacter</em><em>ia</em>
Answer:
B. The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by modifying its bases and blocking the restriction enzyme.
Explanation:
There are two main reasons why bacteria cuts the viral DNA sequence but not its own.
1) There are specific restriction sites in the genome sequence of bacteriophage that restriction enzymes identify and target. These restriction sites are not present in the genome sequence of bacteria.
2) Even if sometimes the bacteria has a sequence resembling to bacteriophage and has the restriction site, still bacteria prevents the cleavage of its own chromosomes by methylating the bases of the restriction sites. When restriction site is methylated, bacteria just cannot chop it down that prevents it overall from degradation(please see the figure for better understanding).
Note: <em>Although option A can also somehow fit but option B is the perfect option because of the reason no 2.</em>

<span>The impulsive mechanism described by Freud is known as the Id. According Freud, the id is the unconscious part of the human mind that wanted to be satisfaction that holds hidden instincts and desire for action. He said that for some people this is not suppressed and are controlled by their Id. This shows their negative behavior without any sense of undertanding right decisions. </span>

Answer:
Air Masses
Explanation:
When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
