5. Someone for whom it is impossible to produce child is known as infertility while for someone for whom it is difficult to become pregnant or carry to term is known as subinfertility.
6. Low body weight and low secretion of LH and FSH prevent ovulation which is common cause of fermale infertility.
Luteinizing hormone (LH) and Follicular stimulation hormone (FSH) induce ovulation in female.
7. The study of human population is also called as demography.
8. Two ways of individual leaving a population are through death and emigration.
Both these will reduce population size. On the other hand, through birth and immigration individuals enter a population.
9. The current population growth rate (PGR) = 1.09%
Doubling time = 70/PGR = 70/1.09 = 64.22 =64 years
Year at which the population doubles = 2018 + 64 = 2082
So the population will double iun about 64 years ( by 2082).
10. The purpose of life according to evolutionary biology is to reproduce.
Hence, the organism makes sure that the lineage continues.
11. In order for a trait to be adaptive the benefits must be greater than the cost.
