Answer:
<em>Ecological succession</em>
Explanation:
Ecological succession can be described as a series of processes by which a climax community arises gradually in an area where there was no form of life before or the previous ecosystem was destroyed bu disasters such as fire, flood etc.
Ecological succession is of two types:
Primary succession occurs on lands where there was no form of life before. On the other hand, secondary succession occurs in lands where there was an ecosystem before which was destroyed.
Answer:
stem cell can differentiate to form heart muscle cells.
Explanation:
Stem cells are self-renewal undifferentiated cells present in the human body. Undifferentiated means that they can divide and differentiate into many cell types of the body depending upon the differentiating potency of the stem cell.
If scientists could regulate the process of differentiation, they can able to differentiate a stem cell into a cell type of interest such as cardiac cell.
These cells are then can be used to replace the damaged or dead cells present in the body.
Thus, it can help in the treatment of diseases such as cardiovascular disease.

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.
=============================================
For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.
Recall that
distance = rate*time
we can rearrange things to say
rate = distance/time
So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.
----------
So,
rate = distance/time
rate = (260 meters)/(180 seconds)
rate = (260/180) meters per second
rate = 1.44 meters per second, which is approximate
I'm rounding to 3 sig figs.
