Q: Answer the following question given this paragraph: Carbohydrates include sugars, starches, and fiber. Sugars and starches are used by the body for energy. One gram of sugar or starch provides 4 Calories of energy. Fiber doesn't provide energy, but it is needed for other uses. At age 13 years, you need about 130 grams of carbohydrates a day. Figure below shows good food sources of each type. Q: How many calories of energy does one gram of sugar or starch provide? A:
Answer: 4

Problem:OPTIONS:
- increase yield
- decrease heat
- slow it down
- speed it up

Answer the following question given this paragraph: Enzymes are extremely efficient in speeding up reactions. They can catalyze up to several million reactions per second. As a result, the difference in rates of biochemical reactions with and without enzymes may be enormous. A typical biochemical reaction might take hours or even days to occur under normal cellular conditions without an enzyme, but less than a second with an enzyme. Q: Enzymes in cellular reactions work to do what to the reaction? A:
****
A: speed it up

Answer the following question given this paragraph: Electricity is a flow of electrons. Atoms of metals tend to give up electrons, explaining why they are good conductors of electricity. The tendency to give up electrons also explains many of the other properties of metals. Q: Why are atoms of metals good conductors of electricity? A:
OPTIONS:
- break into smaller parts
- conserve heat
- hold on to electrons
- give up electrons
give up electrons

Answer the following question given this paragraph: Q: What type of molecules are found in the hydration shell of a dissolved ion? A:
OPTIONS:
- iron
- carbon
- oxygen
- water

Answer: water

Question: Answer the following question given this paragraph: The sporozoans are protists that produce spores, such as the toxoplasma . These protists do not move at all. The spores develop into new protists. Q: What is the term for protists that produce spores, such as the toxoplasm? A:
OPTIONS:
- protozoans
- spermatozoa
- newborns
- sporozoans
Answer: sporozoans

input: OPTIONS:
- sheath and a cathode
- anode and sheath
- anode and diode
- anode and a cathode Now, answer this question: Answer the following question given this paragraph: These values suggest that water should be oxidized at the anode because a smaller potential would be neededusing reaction (ii) for the oxidation would give a less-negative cell potential. When the experiment is run, it turns out chlorine, not oxygen, is produced at the anode. The unexpected process is so common in electrochemistry that it has been given the name overpotential. The overpotential is the difference between the theoretical cell voltage and the actual voltage that is necessary to cause electrolysis. It turns out that the overpotential for oxygen is rather high and effectively makes the reduction potential more positive. As a result, under normal conditions, chlorine gas is what actually forms at the anode. Now consider the cathode. Three reductions could occur:. Q: What are the two metals within a battery called? A:
A:
output:
anode and a cathode
