There are five mechanisms involve in diversity of organisms:
genetic drift, mutation, natural selection, gene flow and non random mating.
Explanation:
Genetic drift: It is a mechanism in which frequency of the allele changes within a population due to random sampling. It causes decrease in diversity in organism and can result in new species.
Mutation: Mutation in the genes is the most important reason of diversity.the change in DNA causes introduction of new alleles. Harmful mutations do not le species evolve by delimiting them from reaching sexual maturity.
Gene flow: The allele flow happens when a new gene is introduced into a population either by immigration or random mating. when two populations of same species share genes, variation occurs.
Natural selection: The favourable traits for survival are transferred to the offspring. It allows them to adapt better to the environment. It allows maintenance diversity of organism.
Non random mating: The mating between the individual with varied genotype will result in genetic variation.
Heat can be transferred from one place to another by three methods: conduction in solids, convctn in fluids, and radiation through anything that will allow radiation to pass. The method is used to transfer the heat is usually the one that is the most efficient

The dendrites. They are the ones that receive information from the previous neuron. (is the post-synaptic membrane)
The post-synaptic membrane receives a signal from the pre-synaptic membrane. (axon terminal)
