1. The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. As a hollow, muscular pump, its main function is to propel blood throughout the body.
2. Arterial blood (red, oxygen-rich blood) flows from the heart to each part of the body to provide oxygen and nutrients. The venous blood (blue, oxygen-poor blood) returns from the body to the heart. The blood then travels through the lungs to exchange carbon dioxide for new oxygen.

iris [78.8K]

Answer:

Le châtelier's principle states that if a stress is applied to a system in dynamic equilibrium, the system changes to relieve the stress.

Explanation:

This principle shows that when we change a system in equilibrium, it will seek to acquire a new state that nullifies this disturbance. Thus, there is a displacement of equilibrium, that is, a search for a new equilibrium situation, favoring one of the senses of the reaction. If it favors the direct reaction, with formation of more product, we say that the equilibrium has shifted to the right. However, it is said that it shifted to the left if the reverse reaction was favored, with formation of reagents.

Proton pumps embedded in the cell membrane use ATP to move hydrogen ions across the membrane. Which of the following best descri
DIA [1.3K]

Answer:

Explanation:

Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.
