Answer:
The greatest of environmental factors on phenotype is on phenotypic plasticity, phenotypes that may change due to changes in the environment; ex: snowshoe hare have brown-colored fur in summer/spring and white fur in winter. Environmental factors may affect gene expression which may result in normal/abnormal phenotypic changes.
Explanation:
Living in a tropical environment where one learns to orient oneself through a vertical landscape of tall trees and speckled light is part of spatial orientation.
<h3>What is the rain forest zone?</h3>
The tropical rain forest zone is the zone that is known to have a very high amount of rainfall for most of the year. The rain forest zone often has a lot of luxuriant trees that blossom all year round and serve as a breeding ground for many insects such as mosquitoes.
Most of the trees in the tropical rain forest zone are arranged in strata where the tallest trees often form a sort of canopy in the area thereby reducing the light that gets to the pants that are found below and keeping the area cool.
Hence, living in a tropical environment where one learns to orient oneself through a vertical landscape of tall trees and speckled light is part of spatial orientation.

The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.
The chromosomes line up neatly end-to-end along the centre (equator) of the cell.
The centrioles are now at opposite poles of the cell with the mitotic spindle fibres extending from them.
The mitotic spindle fibres attach to each of the sister chromatids.
The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?.
Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.
