<span>If
the population is separated long enough, this means that random sampling in mating
and reproduction, that occurred in the
initial population has been restricted</span><span>. The two population will, therefore, adapt to
their local environments and become reproductively isolated
with time. After long periods of time, the two lizards population will have different
alleles and will not be able to mate and
produce viable offsprings hence will have
speciated.</span>
Mitochondria are made from the process called binary fission. This is the cell division utilized by the prokaryotes. It also has circular DNA that is similar in both size and structure in prokaryotic cells. Mitochondria also has its own DNA different than the DNA found in the nucleus of a cell.
Answer:
As a result of mitosis and meiosis, haploid and diploid cells are formed.
The cell will be diploid if it will have two sets of chromosomes, that is the number of chromosomes will be double than that of haploid one. And all the chromosome pairs in diploid are considered homologous chromosomes. e.g. the somatic cells of the body are diploid cells.
Haploid cells will be those who do not have chromosomes in pairs, a single set of chromosomes is found in them. e.g. the haploid spores or gametes cells. The chromosome number in haploid cells are represented as 'n'. Haploid cells are produced via meiosis in cell division.
Answer:
Their function is to package DNA into structural units called nucleosomes. Histones are the main proteins in chromatin. Chromatin is a combination of DNA and protein which makes up the contents of a cell nucleus. Because DNA wraps around histones, they also play a role in gene regulation.
I hope this helped and is the right answer.
