C) evolution by natural selection, Galapagos finches
D) inheritance by independent assortment, Galapagos finches
Correct answer: C). Evolution by natural selection, Galapagos finches
Charles Darwin gave the theory of natural selection in the year 1835 when he visits Galapagos Islands.
There he found several species of finches are adapted to different environmental niches. They have a different shape of the beak, food source they eat and the way they captured the food.
He observes that species vary from island to island, and based on these observations he gave the theory of natural selection.
Oxygen and carbon dioxide pass through the plasma membrane by simple diffusion, a process of passive transport that moves these gases down their concentration gradient. Certain other substances rely on facilitated transport, another type of passive transport, to cross the membrane.
Oxygen and carbon dioxide pass through the plasma membrane by simple diffusion. The structure of the lipid bilayer, composed of hydrophobic phospholipids, allows small, uncharged molecules such as oxygen and carbon dioxide to diffuse down their concentration gradient. This process is a form of passive transport, meaning it doesn't require energy input from the cell.
When there is a higher concentration of oxygen or carbon dioxide outside the cell than inside, these gases will naturally diffuse across the membrane, moving from an area of higher concentration to an area of lower concentration. The same concept applies when there's a higher concentration of these gases inside the cell; they will diffuse out of the cell into the extracellular fluid where their concentration is lower.
Also note that some polar substances and other molecules that do not easily pass through the membrane rely on facilitated transport. This is another type of passive transport where specific integral proteins or glycoprotein receptors on the cell membrane help these substances cross the membrane down their concentration gradient.
