The earth began as a cloud of dust and hot, shining gas. When our planet began to cool, its surface solidified, surrounded by clouds of water vapour. When this vapour condensed (changed into liquid) and began to fall like rain, seas, and oceans formed in the hollows of the Earth’s surface. Oceans are huge expanses of water which separate the Earth’s continents. The largest ocean is the Pacific Ocean, second, the Atlantic and third largest, the Indian Ocean. Seas are smaller expanses of water, almost always flowing either into oceans or other sea. The waters of the seas and the oceans are always salty, because they are rich in mineral salts and especially sodium chloride, which is the salt used in cooking.

Answer:

the ocean formed from the escape of <u>water vapor and other gases from the molten rocks.</u>

Explanation:

After the earth's surface had cooled to a temperature below the boiling point of water , rain began to fall - and continued to fall for centuries . Hope this helped .

Answer and Explanation:

Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.

The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.

In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).

in order to keep a resting membrane potential, the active transport of the sodium and potassium pump must function to keep:

krek1111 [17]

The active transport of the sodium and potassium pump must work to maintain: A high concentration of sodium outside the cell and a high concentration of potassium inside the cytosol in order to maintain a resting membrane potential.

Active transport in cellular biology refers to the movement of molecules or ions across a cell membrane against the concentration gradient from a location of lower concentration to a region of higher concentration. Cellular energy is needed for active transport to achieve this movement.

The electrical potential differential across the plasma membrane of a cell during its non-excited condition is referred to as the resting membrane potential of the cell. The value of the electrical potential difference inside a cell compared to the extracellular environment is often used to indicate the difference across a cell membrane.
