Biogeographic isolation refers to the separation of the members of the similar species, or a group of organisms, which breed and generate offspring that can further give rise to young ones.  
The separation can be achieved by the geographical forces like oceans, rivers, and mountains, and by the biological forces, like hunting times, and spring or fall mating.  
 
        
                    
             
        
        
        
Coronary
arteries supply blood to the heart muscle, The left one, arises from the aorta and
feeds blood to the left side of the heart and the right one supplies blood to
the right ventricle, the right atrium, and the SA (sinoatrial) and AV
(atrioventricular) nodes, which regulate the heart rhythm.
Blockage
in this vessel result in
<span>reducing
the flow of oxygen and nutrients to the heart muscle and that can lead to a
heart attack. Atherosclerosis and arteriosclerosis are the most common causes
of heart disease.</span>

Answer:
True
Explanation:
Meiosis is the kind of cell division that results in the production of daughter cells with each cell having half number of chromosomes as the parent cell. Meiosis is the cell division employed by reproductive cells to produce gametes/sex cells. Meiosis occurs in two stages i.e. Meiosis I and II. The chromosome number reduces by half in gametes in order to ensure that after fertilization of both male and female gamete, the resulting organism has the correct set of chromosomes. e.g diploid organism produces haploid gametes which fuses to produce a diploid organism again.
Mitosis is another type of cell division that results in identical daughter cells. They are identical in the sense that they possess the same number of chromosomes as the parent cell that divided. For example, a diploid cell undergoes mitosis to produce two diploid daughter cells.
