Explanation:

Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements. Much of a cell's supply of metabolic energy may be spent maintaining these processes.

How does geographic distribution of organisms support evolutionary theory?

Serga [27]

Because the organism is distributed across the world, and isn't seen anymore, scientists can conclude tat they must have evolved. They can compare one species to the fossils they may have found, and determine that they were related. Then by looking at the species on another part of the world compare the same fossils to other animals and determine that they are similar, sharing a common ancestor.

The heart is the major organ in the circulatory system. Which region of the heart supplies oxygenated blood to the aorta?

aev [14]

The LEFT VENTRICLE of the heart supplies oxygenated blood to the aorta.

Aorta is the main artery that supplies oxygenated blood from the heart to other organs and tissues (except lungs, lungs are for gas exchange instead) so that they get enough oxygen and nutrients.

Meanwhile, the heart has 4 chambers, left and right atrium, and left and right ventricles. Atrium are for receiving blood from different vessels, and ventricles are for pumping blood out of the heart.

Since only the left ventricle is connected to the aorta, so, the answer should be left ventricle.
