Answer the following question given this paragraph: Digestion and Absorption Digestion is the mechanical and chemical break down of food into small organic fragments. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across the digestive epithelium. Large, complex molecules of proteins, polysaccharides, and lipids must be reduced to simpler particles such as simple sugar before they can be absorbed by the digestive epithelial cells. Different organs play specific roles in the digestive process. Q: What process is used to chemically and mechanically break down the food you eat into smaller parts? Choices: - absorption - regression - filtration - digestion A:
digestion

Answer the following question given this paragraph: All living things consist of one or more cells. Cells are the basic units of structure and function of living organisms. Q: What are the basic units of structure and function in living organisms? Choices: - proteins - molecules - lipids - cells A:
(Answer)
cells
Ques: Answer the following question given this paragraph: A mutation may have no effect. However, sometimes a mutation can cause a protein to be made incorrectly. A defect in the protein can affect how well the protein works, or whether it works at all. Usually the loss of a protein function is detrimental to the organism. Q: What phenomenon can cause a protein in an organism to be made incorrectly? Choices: - evolution - heredity - allele - mutation A:
Ans: mutation

Answer the following question given this paragraph: Figure below shows how phospholipid molecules are arranged in a cell membrane. One end (the head) of each phospholipid molecule is polar and attracts water. This end is called hydrophilic ("water loving"). The other end (the tail) is nonpolar and repels water. This end is called hydrophobic ("water hating"). The nonpolar tails are on the inside of the membrane. The polar heads are on the outside of the membrane. These differences in polarity allow some molecules to pass through the membrane while keeping others out. You can see how this works in the video at the URL below. Q: The end of the phospholipid molecule that is polar and attracts water is called what? Choices: - cytosolic - hydrophobic - magnetic - hydrophilic A:
(A).
hydrophilic
