Q: Answer the following question given this paragraph: Conceptual Questions 19.1 Electric Potential Energy: Potential Difference 1. Voltage is the common word for potential difference. Which term is more descriptive, voltage or potential difference? 2. If the voltage between two points is zero, can a test charge be moved between them with zero net work being done? Can this necessarily be done without exerting a force? Explain. What is the relationship between voltage and energy? More precisely, what is the relationship between potential difference and electric potential energy? 4. Voltages are always measured between two points. Why? 5. How are units of volts and electron volts related? How do they differ?. Q: What is the common word for potential difference in a circuit? A:

OPTIONS:
- watt
- velocity
- frequency
- voltage

A: voltage

input: OPTIONS:
- sponges
- monocots
- heterotrophs
- autotrophs Now, answer this question: Answer the following question given this paragraph: CHAPTER SUMMARY 5.1 Overview of Photosynthesis The process of photosynthesis transformed life on earth. By harnessing energy from the sun, photosynthesis allowed living things to access enormous amounts of energy. Because of photosynthesis, living things gained access to sufficient energy, allowing them to evolve new structures and achieve the biodiversity that is evident today. Only certain organisms, called autotrophs, can perform photosynthesis; they require the presence of chlorophyll, a specialized pigment that can absorb light and convert light energy into chemical energy. Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules (usually glucose) and releases oxygen into the air. Eukaryotic autotrophs, such as plants and algae, have organelles called chloroplasts in which photosynthesis takes place. Q: What are the only organisms that can perform photosynthesis? A:
A:
output: autotrophs

Answer the following question given this paragraph: Q: How many sets of chromosomes do gametes contain? A:

OPTIONS:
- twelve
- four
- eight
- single

Answer: single

Problem: OPTIONS:
- plumbing systems
- thermal systems
- electromagnetic systems
- hydraulic systems
Q: Answer the following question given this paragraph: Hydraulic car lifts also use fluid to transmit pressure and increase force. The lifts are used to raise cars, which are very heavy, so mechanics can work on them from underneath. Controls in airplanes use fluids to transmit pressure and increase force so a flick of a switch can raise or lower heavy landing gear. To see animations of hydraulic systems such as these, go to URLs:. Q: What kind of systems use fluid to transmit pressure and increase force? A:
Answer: hydraulic systems

Problem:OPTIONS:
- diffuse and recede
- surge and drown
- repel and attract
- topple and break

Answer the following question given this paragraph: Figure below shows what happens to waves near shore. As waves move into shallow water, they start to touch the bottom. The base of the waves drag and slow. Soon the waves slow down and pile up. They get steeper and unstable as the top moves faster than the base. When they reach the shore, the waves topple over and break. Q: What happens when waves reach the shore? A:
****
A: topple and break

Problem:OPTIONS:
- baby
- couple
- LIfe
- birth

Answer the following question given this paragraph: Q: Many deleterious alleles have such severe effects that a homozygous embryo spontaneously aborts long before what? A:
****
A:
birth
