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

This is untrue. The mantle is far large than the crust and there are other large size differences.
        
                    
             
        
        
        
Answer:
During meiosis, an event known as chromosomal crossing over sometimes occurs as a part of recombination. In this process, a region of one chromosome is exchanged for a region of another chromosome, thereby producing unique chromosomal combinations that further divide into haploid daughter cells.
