input with options: Answer the following question given this paragraph: Small nonpolar molecules can easily diffuse across the cell membrane. However, due to the hydrophobic nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot do so. Instead, they diffuse across the membrane through transport proteins. A transport protein completely spans the membrane, and allows certain molecules or ions to diffuse across the membrane. Channel proteins, gated channel proteins, and carrier proteins are three types of transport proteins that are involved in facilitated diffusion. Q: Due to the __________ nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot easily diffuse across the cell membrane. A:
OPTIONS:
- hydrophylic
- saturated
- catalytic
- hydrophobic
output: hydrophobic

Q: Answer the following question given this paragraph: Only the top 200 meters or so of water receive enough sunlight for photosynthesis. This part of the water is called the photic zone. Below 200 meters, there is too little sunlight for photosynthesis to take place. This part of the water is called the aphotic zone. In this zone, food must come from other sources. It may be made by chemosynthesis, in which microorganisms use energy in chemicals instead of sunlight to make food. Or, food may drift down from the water above. Q: What is the top part of water able to receive enough sunlight for photosynthesis called? A:

OPTIONS:
- thymic zone
- synthesis zone
- fantasmic zone
- photic zone

A: photic zone

input: OPTIONS:
- circuit cell
- switch cell
- photo cell
- voltaic cell Now, answer this question: Answer the following question given this paragraph: One application of redox reactions requires that they be physically separated. Even though the two half reactions are physically separated, a spontaneous redox reaction still occurs. However, in this case, the electrons transfer through the wire connecting the two half reactions; that is, this setup becomes a source of electricity. Useful work can be extracted from the electrons as they transfer from one side to the otherfor example, a light bulb can be lit, or a motor can be operated. The apparatus as a whole, which allows useful electrical work to be extracted from a redox reaction, is called a voltaic (galvanic) cell. Each individual system that contains a half reaction is called a half cell. The half cell that contains the oxidation reaction is called the anode, while the half cell that contains the reduction reaction is called the cathode. The cathode and anode collectively are the electrodes of the voltaic cell. Because electrons are coming from the anode, the anode is considered the negative electrode of the cell, while the cathode is considered the positive electrode of the cell. Finally, because electrons are moving from one half cell to the. Q: The cathode and anode collectively are the electrodes of what? A:
A:
output: voltaic cell

- stems
- roots

Answer: roots

Problem: OPTIONS:
- clumping
- oxidation
- plasma
- coagulation
Q: Answer the following question given this paragraph: You can see how water for drinking is treated in Figure below . Treating drinking water requires at least four processes: 1. Chemicals are added to untreated water. They cause solids in the water to clump together. This is called coagulation. 2. The water is moved to tanks. The clumped solids sink to the bottom of the water. This is called sedimentation. 3. The water is passed through filters that remove smaller particles from the water. This is called filtration. 4. Chlorine is added to the water to kill bacteria and other microbes. This is called disinfection. Finally, the water is pure enough to drink. Q: When drinking water is treated, what is the term for when chemicals cause solids in the water to clump together? A:
Answer: coagulation

Answer the following question given this paragraph: Amines are capable of hydrogen bonding though their boiling points are generally a bit lower than the corresponding alcohol. Methylamine and ethylamine are gases at room temperature, while larger amines are liquids. As with other organic compounds that form hydrogen bonds, water solubility is reflected in the length of the carbon chains. Smaller amines are soluble, while larger ones are less soluble. Q: As with other organic compounds that form hydrogen bonds, water solubility of amines is reflected in the length of what? A:

OPTIONS:
- hydrocarbon bonds
- complex carbohydrates
- nuclei chains
- carbon chains

Answer:
carbon chains
