Answer to Question 1

spermatogenesis

Answer to Question 2

The effects of pollution depend on the concentration (amount per unit of air, water, or soil) of the pollutant, how long it remains in the environment, and its chemical nature.

 An acute effect is a severe, immediate reaction, usually after a single, large exposure. For example, pesticide poisoning can cause nausea and dizziness, even death.

 A chronic effect may take years to develop or may be a recurrent or continuous reaction, usually after repeated exposure. Years of exposure to traffic pollution, for instance, has been linked to an increase in blood pressure.
