6 0

Answer:

A symbol that indicates the sedimentary rocks (for example, salt rocks).

Explanation:

The sedimentary rocks are formed through time by cycles of evaporation and the consequent deposition of minerals. In the case of salt rocks, for example, they are generated by the accumulation of layers of salt in the seashore through the movement of the sea waves, i.e., by the evaporation of seawater and subsequent accumulation of salt.

Which statements explain the gas exchange that happens at the alveoli? Check all that apply.
Anuta_ua [19.1K]

Answer:

B. Carbon dioxide moves from the blood to the air in the alveoli.

C. The capillaries that surround the alveoli exchange both carbon dioxide and oxygen.

E. Oxygen is absorbed by the blood in the capillaries that surround the alveoli.

Explanation:

Alveoli are the small sacs that are present in the lungs. Main function of alveoli is to exchange gases i. e. oxygen and carbondioxide with the blood that is present in the capillaries of the lungs. Blood that comes from the cell has high concentration of carbondioxide so it is taken by the alveoli and the oxygen present in the alveoli is absorbed by the cell. About 480 millions of alveoli are present in human lungs.

Why are there species instead of a continuum of various animals?
melamori03 [73]
Because evolution itself is a very slow process. Having said that, the chance of having a continuum of various animals would mean that evolution would have progressed very fast. Because evolution is slow, different species establish themselves for different ecological niches and environments, this enables them to become better through time at a certain environment which then leads to eventual diversification in the number of species.
