The correct answer is "fiber".
Fiber is actually indigestible food products such as cellulose that aids in the digestion and bowel function. Fiber, first of all, limits the absorption of extra fats therefore preventing hypertriglyceridemia and eventually cerebrovascular and cardiovascular consequences. Fiber also limits glucose absorption controlling type II diabetes. Lastly, fiber also acts as protection in the colon by increasing the transit times of potentially carcinogenic substances found in food, therefore preventing colon cancer.
Answer:
Because of the chemical and structural nature of the phospholipid lipid by layer the lipid soluble molecule can just pass the lipid membrane and some small molecules can also pass freely.
Explanation:
as we know that the homeostasis is an important process for a living cell to maintain it self so for the the exchange of materials between the external and internal environment is must so for that it exchange material with the outside environment of the cell.as the cell membrane is semipermeable(mean allow some molecule to pass(lipid soluble) and not others(lipid non soluble) to pass through the membrane.the cell membrane is selectively permeable due to its nature and chemical composition the chemical composition is lipid and phosphate and glycerol(head) with fatty acid that may b saturated or unsaturated(tail).so finally all those molecule which are polar can not pass through the membrane and non polar can pass the membrane.The size of the molecule is also a factor on which the permeability depends.

Answer:
We can see some of the most important patterns Darwin noticed in distribution of organisms by looking at his observations of the Galápagos Islands off the coast of Ecuador. Darwin found that nearby islands in the Galápagos had similar but nonidentical species of finches living on them.
