The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.
Nonrenewable resources are used commonly and are quickly running out, and it takes longer for us to form more of these.
A population with a lot of genetic variation would likely have more phenotypic variation; therefore, such a population would more likely have individuals that can adapt to a changing environment. mutation can result in new alleles on chromosomes. ... this is the same effect that genetic drift can have on small populations.
