Charles is an engineer who is evaluating a prototype of an artificial heart. The prototype beats in a synchronized fashion, is h

ollow, 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.

Destruction of tropical rain forests: helps maintain global temperatures
aliya0001 [1]

Answer:

B. reduces the amount of water vapor

Explanation:

Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.

One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.

The best kind of model for the scientist to use is an interactive model of the planets' orbits on a computer.

<h3>What is the law of orbits?</h3>

Kepler's first law, also known as the law of orbits, describes the shape of planetary orbits. According to this law, the planet's orbits around the Sun are elliptical, despite having very small eccentricities.

For this reason, it is necessary to know all the orbits of the planets in an interactive way, since according to Kepler's law, the orbits decrease over time.
