Answer:
B.
Explanation:
basically when the stem cell in the crypts divides they formed daughter cells. One of the daughters from each of the original divided stem cells usually divides to form another stem cell, while the rest forms transit amplifying cell.These amplifying cells are capable of dividing multiple times until they are evenly differentiated(designated to specific function) e.g top globlet cells, enterocytes, tuft cells etc.
The reaction proceeds with a net release of free energy.
Improving our technology lead to new discoveries about Mars because the new technology helps us to find more information about the environment of the Mars planet.
<h3>How did improving our technology lead to new discoveries about Mars?</h3>
Scientists use Terrain-Relative Navigation which is a device due to which the Perseverance rover can estimate its location while moving through the atmosphere of Mars on its parachute. Improvement in our technology lead to new findings about Mars. The new technology helps us to collect more data about the Mars planet.
So we can conclude that Improving our technology lead to new discoveries about Mars because the new technology helps us to find more information about the environment of the Mars planet.

Answer:
Explanation:
tobacco mossaic virus is aa RNA containing virus enclosed in aaprotein coat. in above sttaed experiment when TMV cause infection in tobacco plant is leaves get infected due to replication of virus in its cells. RNA is first converted into complementary DNA and form a double stranded nucliec acid structure. it syntheaize its protein to make new coats and to wrap the newly synthesized RNA, and make a completely infected new virus which we called virion. in any case the number of coats are equal to RNA so that to prepare new viruse. n
