Transmission of nerve impulses between two neurons takes place at through the synapse. The axon terminal of a neuron releases specialized chemicals; called neurotransmitters. These chemicals travel through the synapse and reach the dendrites of the next neuron. The nerve impulses travel along with tRead more

Reproduction is the process of producing new individuals of the same species by existing organisms of a species, so, it helps in providing stability to population of species by giving birth to new individuals as the rate of birth must be at par with the rate of death to provide stability to populatiRead more

Unicellular organisms reproduce by asexual methods like fission, budding while multicellular organisms reproduce by sexual method & asexual method both. For ex. Guava is a multicellular plant that reproduce by vegetative propagation and sexual reproduction.
