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

Their reproductive isolation from each other is complete: False  
They are unable to produce hybrid offspring upon interbreeding: True  
They shared a common ancestor recently in evolutionary time: False  
Explanation:
A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.  
This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
