4 0

Answer:

Option D, aortic valve

Explanation:

The location of aortic valve i.e between the aorta and left ventricle,  allows it to stop the blood from flowing back into the left ventricle.

The other options are incorrect as -  

Pulmonary valve being located between the pulmonary artery and right ventricle, stop the blood from flowing back into the right ventricle.

The tricuspid valve and mitral valve stops the blood from flowing back into the right atria and left atria respectively.  

Hence, option D is correct.

Airida [17]
Unlike natural selection, genetic drift does not depend on an allele's beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
