One of these principles, now known as Mendel's law of independent assortment, states that allele pairs separate during the formation of gametes. This means that traits are transmitted to offspring independently of one another.
Hi there!
The lower the area, the warner it is, because of the change in air pressure. Less air and less air pressure results in colder temperatures even though higher places may be closer to the sun.
Hope this helps!
Answer:
Deforestation is the major problem causing lack of rich species in Costa Rica. This is due to over grazing by cattle.This may lead to flooding which affect fertility of the soil.These animals graze on the plants without regulations,and cause erosion as their hoofs percolate the soil, further reducing soil fertility.
In addition to sustain the beef production, trees were fell to for cattle ranching.This ultimately contributed to loss of the forest species.
Banana plantation is an additional factor.Forest were cleared to cultivate banana, which affects forest population.
