Answer:

Water

Explanation:

This is actually a chemistry question but I'll answer it anyways

The definition of a chemical compound is " a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. "

Compounds are homogenous, which means that they are evenly distributed and have 2 or more different elements from the definition

Therefore the answer is that water is a compound as its chemical make up is H2O.

Gold is made up of 1 element

Oxygen is made up of 1 element,

Hydrogen is made up of 1 element

Therefore these options are not viable since they do not contain 2 or more elements.

Scorpion4ik [409]

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.

Can you explain how more life-forms were able to create because of cyanobacteria​ PLEASE HELP
Ainat [17]

The cyanobacteria changed the composition of the earth’s atmosphere by evolving oxygen in what is referred to as the Great Oxygenation Event. This also allowed the ozone to be formed and block off most of the UV rays that are destructive to genetic material. Life was, therefore, also able to exist on land other than in water.
