Answer:
Pangenesis
Explanation:
The theory of 'pangenesis' was proposed by Darwin to explain the process of inheritance of genetic traits from one generation to next. According to this theory, gemmules are the tiny particles produced by all the somatic cells of the body of living beings. These gemmules are also called pangene. Blood carries gemmules from all the body cells to the gonads. These gemmules from all the somatic cells form germ cells in gonads.
Science is valued by society because the application of scientific knowledge helps to satisfy many basic human needs and improve living standards. Finding a cure for cancer and a clean form of energy are just two topical examples.
