Charles is an engineer who is evaluating a prototype of an artificial heart. the prototype beats in a synchronized fashion, is hollow, and has tubes attached to it. it can be powered by electrical signals from the brain when it is interfaced with the appropriate nerves. what important feature should charles notice the prototype is missing?

blood vessels to transport blood

a structure that would divide the hollow heart into chambers to separate oxygenated blood from deoxygenated blood

a blood filtering mechanism to separate oxygenated blood from deoxygenated blood

a structure to pump blood through the valves

The correct answer is a structure that would differentiate the hollow heart into chambers to separate oxygenated blood.

The heart has four chambers: two ventricles and two atria. The right atrium gets oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-deficient blood to the lungs.

The left atrium gets oxygen-enriched blood from the lungs and pumps it to the left ventricle, and the left ventricle pumps the oxygen-enriched blood to the body. The right and left atrium are distinguished by a wall of tissue known as the atrial septum, and the left and right ventricles are separated by the ventricular septum.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
