If the membrane of a cell were no longer selectively permeable then "The cell would die as it would not be able to regulate which substances could enter and leave", since a selectively permeable membrane allows both things to enter and leave for the cell's survival.
Answer:
246
Explanation:
Increased amount / current population = 972
Amount released = 108
time(t) = 2years
Using the exponential growth function :
f(t) = A*g^t
Where g = growth rate
To obtain the growth rate = g
972 = 108 * g^2
g^2 = 972 / 108
g^2 = 9
g = 3
To determine population after 9 months :
9 months to years = (9/12) = 0.75
t = 0.75
f(0.75) = 108*(3^0.75)
f(0.75) = 108 * 2.2795070
f(0.75) = 246.18676
= 246
Explanation:
Having filtered out small essential molecules from the blood - the kidneys must reabsorb the molecules which are needed, while allowing those molecules which are not needed to pass out in the urine. Therefore, the kidneys selectively reabsorb only those molecules which the body needs back in the bloodstream.
