Answer: Spermatogenesis begins at birth and continues throughout a man's life.
The process in which

The speed of the cross country runner is equal to 4 km/min.
<u>Given the following data:</u>
To determine the speed of the cross country runner:
Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).
Mathematically, speed is given by the formula;
Substituting the given parameters into the formula, we have;
Speed = 4 km/min.
