Answer:
It provides evidence for evolution and adaptations
Explanation:
Answer:
Erythrocytes, or red blood cells, are the most numerous of the formed elements. <u>Erythrocytes are tiny biconcave disks, thin in the middle and thicker around the periphery. </u>The shape provides a combination of flexibility for moving through tiny capillaries with a maximum surface area for the diffusion of gases.
The cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell. Cells also maintain a higher concentration of potassium ions and organic acids on their inside.

-Organisms had adapted to new environments, giving rise to new species
From his observations of organisms in the galapagos islands, darwin reasoned that organisms had adapted to new environments, giving rise to new species.
Explanation;
-On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
-He noticed that each finch species had a different type of beak, depending on the food available on its island. The finches that ate large nuts had strong beaks for breaking the nuts open.
