Answer the following question given this paragraph: 27.5 Single Slit Diffraction Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings. Figure 27.21 shows a single slit diffraction pattern. Note that the central maximum is larger than those on either side, and that the intensity decreases rapidly on either side. In contrast, a diffraction grating produces evenly spaced lines that dim slowly on either side of center. Q: What kind of lines does a diffraction grating produce? A:

OPTIONS:
- nearly spaced lines
- properly spaced lines
- randomly spaced lines
- evenly spaced lines

Answer: evenly spaced lines

Problem: OPTIONS:
- hypothesis
- frequency
- diversity
- accuracy
Q: Answer the following question given this paragraph: In measuring quantities we always aim for high accuracy . Estimates that fall within the range of uncertainty for a given instrument are said to be accurate. In our previous example, all of the values between and including 52.4 mL and 53.4 mL would be considered accurate. Estimates that fall outside this range are inaccurate. Accuracy describes how close an estimate is to a known standard. Q: What describes how close an estimate is to a known standard? A:
Answer: accuracy

Problem:OPTIONS:
- reptiles
- amphibians
- insects
- mammals

Answer the following question given this paragraph: The supertree also shows that another major diversification of mammals occurred about 50 million years ago. Again, worldwide climate change may have been one reason. This time Earth's temperature rose. The warmer temperature led to a greater diversity of plants. This would have meant more food for mammals or their prey. Q: A major diversification of what animal group occurred about 50 million years ago, possibly spurred by worldwide climate change? A:
****
A: mammals

Answer the following question given this paragraph: Figure 32.19 Nuclear fusion in the Sun converts hydrogen nuclei into helium; fusion occurs primarily at the boundary of the helium core, where temperature is highest and sufficient hydrogen remains. Energy released diffuses slowly to the surface, with the exception of neutrinos, which escape immediately. Energy production remains stable because of negative feedback effects. Q: What process converts the sun's hydrogen nuclei into helium? A:
OPTIONS:
- solar fission
- nuclear fission
- combustion
- nuclear fusion
nuclear fusion

Answer the following question given this paragraph: All living things depend on their environment to supply them with what they need, including food, water, and shelter. Their environment consists of physical factorssuch as soil, air, and temperatureand also of other organisms. An organism is an individual living thing. Many living things interact with other organisms in their environment. In fact, they may need other organisms in order to survive. This is known as interdependence . For example, living things that cannot make their own food must eat other organisms for food. Other interactions between living things include symbiosis and competition. Q: What is the term for when organisms need other organisms to survive? A:
OPTIONS:
- intradependence
- realization
- coexistence
- interdependence

Answer:
interdependence
