A scientific theory developed by many different experiments are performed and repeated

Answer: Option D

<u>Explanation:</u>

Hypothesis is an experimental analysis where it is not a perfectly proven fact but a guess due to continuous observation over the years. Hypothesis is the foundation for further discoveries and theories.

Theories are based on the group of hypothesis. Theories are not fixed based to prove on the hypothesis, if any alterations are found they repeat it with more innovative ideas. Over the years continuous and repeated experiments are conducted on the same. Theory is an explanation that is given for the hypothesis by conducting various experiments and continuous observation time and again to prove it.

A law is a proved theory. It is more of mathematical derivations and calculations with precision. A 100% proved theory after observation only can be considered as a law.

In complete sentences, explain the path which blood travels in the heart, be sure to include the names of the chambers and major
ehidna [41]

First, deoxygenated blood flows into the right atrium of the heart from the inferior and superior vena cava.

Blood then flows through the bicuspid valve and into the right ventricle.

The blood then flows through the pulmonary valve and into the pulmonary artery. Arteries carry blood away from the heart while veins return blood to the heart. The pulmonary artery is on of the only arteries that carries deoxygenated blood.

Blood will then pass through the lungs and will be oxygenated.

After being oxygenated, the blood enters the pulmonary veins. The pulmonary veins are some of the only veins that carry oxygenated blood.

Blood enters back into the heart through the left atrium.

Then, blood flows into the left ventricle through the mitral valve.

Finally, blood is pumped through the aortic valve, into the aorta, and is distributed throughout the body.

WHICH SPECIES OF ANIMALS ARE AFECTED THE MOST BY ACTIONS OF HUMANS IN CURRENT TIMES?SUGGEST WAYS TO PROTECT THEM.
Finger [1]

Answer:

Polar Bears

Explanation:

The species that has most likely been the most affected by human actions would be the Polar Bears. The human population is growing at a staggering rate and this causes industrialization to expand rapidly as well. This continued and increasing use of fossil fuels for all of our basic necessities is rapidly heating up our world (Global Warming) and melting the ice caps. Without this it becomes nearly impossible for Polar bears to survive as they cannot find shelter and ultimately end up starving to death due to not being able to hunt for food as well. The only way to protect them is to begin protecting our planet, switching to more environmentally friendly sources of energy, and being mindful of our choices.
