Answer:
Cancer is formed when there are mutations in a number of genes.
Explanation:
Malignant tumors are gene diseases which do not mean that cancer is necessarily an inherited disease (only in 5-10% of cases the cancer is inherited) because the vast majority of other tumors are the result of somatic, ie secondary, mutations that lead to malignant transformation.
Only 2% of human diseases are monogenic (caused by a change in one gene). The remaining 98% of the disease is either polygenic (caused by a change in several genes at the same time) or epigenetic (caused by non-genetic or post-genetic disorders of cellular molecules).
Different organisms have different number of chromosomes
Answer:
a move from the fundamental niche to the realized niche for both species.
Explanation:
The niche of an organism is the functional role of the organism in the community or the ecosystem as a whole. This include the environment an organism lives and all the jobs it does in it.
Fundamental niche refers to all the possible functional roles of an organism in an ecosystem while realized niche refers to the specific roles the organism is limited to as a result of resource limitation, competition or other factors.
Resource partitioning involves the division of limited resources among organisms so as to avoid competition within the niche.
<em>Hence, resource partitioning causes a move from the fundamental niche of an organism to the realized niche of that organism. </em>
