Answer:
D
Explanation:
because mintochodria is the power house hence it provides energy to the cell
Answer: C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.
Explanation:
Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation.
Answer: Always and always
Explanation:
Within any large animal population there is always a variety of traits seen in the population. When there is a large number of individuals in a population then there are chances that there a genetic diversity.
Sexual reproduction in the organism can lead to the genetic variation in the organism. There are chances to have more variation in the population having more organism.
Two different organism are genetically different and there are variety of traits seen in the two animals that belongs to different species.
