---------------
Answer: B. Are found in organisms of the same species.
Homologous structures are body parts that are alike because the species in question share a common ancestor.
Answer:
The correct answer is - a density independent factor.
Explanation:
Any external cause or change that leads to the change in the size of a population regardless of the density of the particular population known as a density independent factor in ecology.
Density independent factors are the factors that are not affected by the size of the population size of the species such as weather, climate and natural disasters.
Thus, the correct answer is - a density independent factor.
In unicellular organisms, the process of mitosis serves as a method or form of asexual reproduction, as organisms that are unicellular and are typically prokaryotic undergo mitosis to essentially duplicate and make additional offspring that are genetically identical clones as that of the original parent cell. Mitosis in multicellular organisms serves to replace lost, specifically damaged tissue of the organism, it also is crucial for the growth and development of the organism, as it is this particular portion of the cell cycle, when cells after growing and having their DNA duplicated can they separate and produce more and more cells.
