Solution
4.
a. Coccus would have more survival rate in dry condition in comparison with the rods because it
has less surface to volume ratio than the rods. So in dry condition they can loss minimum water
in comparison with the rods, having higher surface to volume ratio.
b. Rods will be able to adapt in moist condition efficiently than the coccus as they have higher
surface to volume ratio. For this reason they can uptake nutrients very efficiently. Hence, they
would be better adapted in moist condition.
