the answer would be B) Moon
Answer:
Explanation:The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:
[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.
So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.
To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.

Answer: Time required for 100 molecules of valinomycin to transport enough to change the concentration inside an erythrocyte is 10 minutes.
Explanation:
The given data is as follows.
Ions to be transported =
=
= ions
Here, there are 100 ionophores are present and each one of ionophores are required to transport a value of ions.
Therefore, the time required for 100 molecules of valinomycin to transport enough to change the concentration inside an erythrocyte is as follows.
= 602 sec
or, = 10 minutes (as 1 min = 60 sec)
Thus, we can conclude that time required for 100 molecules of valinomycin to transport enough to change the concentration inside an erythrocyte is 10 minutes.
