Question

3. The growing size of the human population is a cause of concern for all people. The rate
of birth and death in a given population
will determine its size. Reproduction is the
process by which organisms increase their
population. The process of sexual maturation
for reproduction is gradual and takes place
while general body growth is still going
on. Some degree of sexual maturation does
not necessarily mean that the mind or body
is ready for sexual acts or for having and
bringing up children. Various contraceptive
devices are being used by human beings to
control the size of population.
(a) List two common signs of sexual maturation in boy and girls.
(b) What is the result of reckless female foeticide?
(c) Which contraceptive method changes the
hormonal balance of the body ?
(d) Write two factors that determine the size
of a population
