How are modes for reproduction different in unicellular and multicellular organiams?
In unicellular organisms, modes of reproduction is asexual like fission, budding, vegetative propagation.
Organism reproduces by division of entire cell.
In multicellular organisms, mode of reproduction is sexual. They contain specialized reproductive organs.
How does reproduction help in providing stability to populations of species?
Stability of a population can be determined by equalizing birth and death ratio.
Birth rate should be approximately equal to the death rate.
What could be the reasons for adopting contraceptive methods?
Contraceptive methods are adopted to
