Answer:B
Explanation:due to osmosis and osmoregulation of the cell membrane
The average speed : 3.07 m/s
<h3>Further explanation</h3>
Given
d1 = 2 km
t1 = 9 min
d2 = 1.5 km
t2 = 10 min
Required
The average speed
Solution
Average speed = total distance : total time
total distance :
= d1+d2
= 2+1.5
=3.5 km
total time :
= t1+t2
= 9 min + 10 min
= 19 min
Average speed :
= 3.5 km : 19 min
= 0.184 km/min
= 3.07 m/s
I believe its a Nonpolar substance.

Explanation:
The mole ratio in a balanced equation tells us the number of moles of each reactant needed and how many moles of product will be made.
We are asked to find the mole ratio between A and D for this reaction.
The mole ratio is found by comparing the coefficients, which are the numbers in front of the formulas.
A has a coefficient of 4 and D has a coefficient of 3.
Therefore, the ratio between A and D is:
- 4:3
