Answer:

D. is not very significant because it gives us little insight into human behavior.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

As a scientific concept, race is not very significant because it gives us little insight into human behavior.

This ultimately implies that, race is a scientific concept that holds no significant or absolute value since the nineteenth century.

Hence, the difference between humans shouldn't be described based on race according to the United Nations Educational, Scientific and Cultural Organization (UNESCO).

What prevents blood movement from left ventricle to left atrium​
irina1246 [14]

The Mitral valve which is also known as left atrioventricular prevents blood movement from left ventricle to left atrium.

Explanation:

  • Human heart is four chambered.
  • Two of these are receiving chambers known as atria and the other two are distributing chamber known as Ventricles.
  • Atria are superior chambers and ventricles are inferior chambers.
  • The heart has four valves broadly grouped as Atrioventricular valves and Semi lunar valves.
  • Atrioventricular valves allows flow of blood from atria to ventricle. These are tricuspid valve and bicuspid valve.
  • Semi-lunar valves allow blood to pass out of the heart. These include the pulmonary and aortic valves.
  • The pulmonary valve allows blood to flow from right ventricle  to the heart while aortic valve allows blood to flow from left ventricle to the Aorta.
  • The Tricuspid valve located between the right atrium and right ventricle allows blood to flow from right atrium to the right ventricle.
  • The Bicuspid valve ( Mitral valve)  located between the left atrium and left ventricle allows the blood flow from left atria to left ventricle.
  • Valves maintain the unidirectional flow of blood and thus prevent its back flow.

Any ideas?
PilotLPTM [1.2K]

I'll choose Golden Retrievers:

These dogs where created for duck-hunters. Their purpose was to go catch the ducks that fell on the lake/river once they were shot by the hunter - here we see how they serve (or actually served) men.

Nowadays, Golden Retrievers are known to like water a lot, and to be very playful with it - and here is where we see a genetic adaptation. They needed to be in water, and were modified to like it.

Hope it helped,
