Answer:
Vacuum
Explanation:
A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.
For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.
<span>Plant cells will also change with the degree of specialization. It means that when is is a higher developed organism then it will have a higher degree of specialization. For the second question,Somatic cells of animal callus are most common to the plant cell. It is because just like a callus, the tissue of the plant cells are thick and it serves them as protection from friction.</span>
