You didn’t put any of the choices for the risks, but I believe something important to consider is making sure that the tourists return the umbrellas.

It is true that uni-potent stem cells can only produce cells that are like themselves
Answer: Option B
<u>Explanation:</u>
Uni potent cell as their name suggests can only produce cells that are just like themselves. Compared to the other stem cells that undergo proliferation this produces a tissue of that particular type alone.
Though it can’t be of much use like other cells giving rise to different cell types this is confined to the generation of one particular tissue. The uni-potent cells help to renovate and recreate themselves too. Hence any damaged tissue can be replaced by the uni-potent cell giving rise to the same tissue in case of burns etc.
When atp is used by a cell to provide the energy for cellular work, the usual end products left over from the atp molecule are ADP
<u>Explanation:</u>
Like every other living thing that needs energy to survive the cells also needs energy for the proper functioning of the organism. Through Cellular respiration the cells derive energy in the form of ATP molecules.
Adenosine triphosphate (ATP) releases energy to the required cell by transferring one phosphate and then becoming Adenosine diposphate (ADP).
Then after it releases energy it is all set up to absorb another phosphate molecule to become ATP. And this is the simple process of acquiring and transferring energy to the cells.
