Answer the following question given this paragraph: If a molecule can pass freely through a cell membrane, it will cross the membrane by diffusion ( Figure below ). The inside of the plasma membrane is hydrophobic, so certain molecules cannot easily pass through the membrane. Recall the semipermeable nature of the lipid bilayer. Molecules that cannot easily pass through the bilayer include ions and small hydrophilic molecules, such as glucose, and macromolecules, including proteins and RNA. Examples of molecules that can easily diffuse across the plasma membrane include carbon dioxide and oxygen gas. These molecules diffuse freely in and out of the cell, along their concentration gradient. Though water is a polar molecule, it can also diffuse through the plasma membrane. The diffusion of water through the cell membrane is of such importance to the cell that it is given a special name, osmosis . Q: What is the special name given to the diffusion of water through the cell membrane? Choices: - hemostasis - passive transport - electrolysis - osmosis A:
osmosis

Answer the following question given this paragraph: A car's gas pedal, like the one in Figure below , is sometimes called the accelerator. That's because it controls the acceleration of the car. Pressing down on the gas pedal gives the car more gas and causes the car to speed up. Letting up on the gas pedal gives the car less gas and causes the car to slow down. Whenever an object speeds up, slows down, or changes direction, it accelerates. Acceleration is a measure of the change in velocity of a moving object. Acceleration occurs whenever an object is acted upon by an unbalanced force. Q: What is the measure of the change in the velocity of a moving object called? Choices: - transmission - compression - pressurization - acceleration A:
(Answer)
acceleration
Ques: Answer the following question given this paragraph: Tiny pinworms are the most common roundworm parasites of people in the U. S. In some areas, as many as one out of three children are infected. Humans become infected when they ingest the nearly microscopic pinworm eggs. The eggs hatch and develop into adults in the host's digestive tract. Adults lay eggs that pass out of the host's body to continue the cycle. Pinworms have a fairly simple life cycle with only one host. Q: What are the most common roundworm parasites of people in the u. s.? Choices: - cutworms - leeches - hookworms - pinworms A:
Ans: pinworms
(Q).
Answer the following question given this paragraph: Quaternary structure is a larger assembly of several polypeptide chains, now referred to as subunits of the protein. The quaternary structure is stabilized by the same interactions as the tertiary structure. Complexes of two or more polypeptides are called multimers. Specifically, a dimer contains two subunits, a trimer contains three subunits, and a tetramer contains four subunits. Q: What structure is a larger assembly of several polypeptide chains that are now referred to as subunits of the protein? Choices: - digital structure - geological structure - pyramid structure - quaternary structure A:
(A).
quaternary structure
Ques:Answer the following question given this paragraph: Q: During sexual arousal what does the clitoris, vagina, and labia minora all engorge with? Choices: - urine - bacteria - fluid - blood A:

Ans:blood
Answer the following question given this paragraph: The other idea is that evolution occurs by natural selection. Natural selection is the process in which living things with beneficial traits produce more offspring than others do. This results in changes in the traits of living things over time. Q: What is the term for the process in which living things with beneficial traits produce more offspring than others do? Choices: - natural process - natural survival - natural variety - natural selection A:
natural selection
