Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
An animal cell can be found in animals n (while plan cells in plants) and has different structures than plant cells do. Plant cells also have vacuoles, cell walls and chloroplast, while animal cells do not.
Allelopathic plants sometimes create some persistent problems to the soil. For example, the residues of allelochemicals may exist in the soil for a long time after the plant is removed; which results in soil sickness and makes some sites unsuitable<span> for general plant growing.

Humans have a density close to 1000 kg/m³ (the density of water). If a human has a mass of 75 kg, the volume would be around 0.075 m³.
Answer:
6 months to 15 years.
Explanation:
However there is no exact time limit to decomposing, it could take up to 6 months to 15 years. To decompose it really relies on the temperature and the state of the environment.
Hope this helps!
