Q: Answer the following question given this paragraph: Figure 5.12 Light energy is absorbed by a chlorophyll molecule and is passed along a pathway to other chlorophyll molecules. The energy culminates in a molecule of chlorophyll found in the reaction center. The energy "excites" one of its electrons enough to leave the molecule and be transferred to a nearby primary electron acceptor. A molecule of water splits to release an electron, which is needed to replace the one donated. Oxygen and hydrogen ions are also formed from the splitting of water. Q: Light energy is absorbed by which kind of molecule? A:

OPTIONS:
- inorganic
- parasite
- nutrient
- chlorophyll

A: chlorophyll

input: OPTIONS:
- plants
- skin
- shrubs
- roots Now, answer this question: Answer the following question given this paragraph: Secondary growth of sweet potato roots provides more space to store food. Roots store sugar from photosynthesis as starch. What other starchy roots do people eat?. Q: What part of the sweet potato store sugar from photosynthesis as starch? A:
A:
output: roots

Answer the following question given this paragraph: The vapor pressure of a solution is lower than that of the pure solvent at the same temperature. This decrease in vapor pressure is one example of a colligative property . Colligative properties are properties of solutions that depend only on the concentration of dissolved particles and not on their identity. Q: What are the properties of solutions called that depend only on the concentration of dissolved particles and not on their identity? A:

OPTIONS:
- platyhelminth properties
- platyhelminth properties
- platyhelminth properties
- colligative properties

Answer: colligative properties

Problem: OPTIONS:
- momentum
- metabolism
- strength
- fitness
Q: Answer the following question given this paragraph: Darwin coined the term fitness to refer to an organism's relative ability to survive and produce fertile offspring. Nature selects the variations that are most useful. Therefore, he called this type of selection natural selection. Q: Darwin coined what term to refer to an organism's relative ability to survive and produce fertile offspring? A:
Answer: fitness

Problem:OPTIONS:
- fast heart beat
- heart burn
- pass out
- heart attack

Answer the following question given this paragraph: A heart attack happens when the blood cannot reach the heart because a blood vessel is blocked. If cardiac muscle is starved of oxygen for more than roughly five minutes, it will die. Cardiac muscle cells cannot be replaced, so once they die, they are dead forever. Coronary heart disease is the leading cause of death of adults in the United States. The image below shows the way in which a blocked coronary artery can cause a heart attack and cause part of the heart muscle to die ( Figure below ). Maybe one day stem cells will be used to replace dead cardiac muscle cells. Q: What happens when the blood cannot reach the heart because a blood vessel is blocked? A:
****
A: heart attack

Problem:OPTIONS:
- amino acid
- acetic acid
- carbonation
- citric acid

Answer the following question given this paragraph: Some solutions have special properties because they are acids. Orange juice is an example. It contains an acid called citric acid. It makes orange juice taste sour. Some solutions are bases rather than acids. Q: What in orange juice makes it taste sour? A:
****
A:
citric acid
