Answer the following question given this paragraph: Waves are characterized by their ability to constructively and destructively interfere . Light waves which interfere with themselves after interaction with a small aperture or target are said to diffract . Q: Light waves which interfere with themselves after interaction with a small aperture or target are said to what? Choices: - refract - adduce - reflect - diffract A:
diffract

Answer the following question given this paragraph: A third important type of soil is laterite . Laterite forms in tropical areas. Temperatures are warm and rain falls every day ( Figure below ). So much rain falls that chemical weathering is intense. All soluble minerals are washed from the soil. Plant nutrients get carried away. There is practically no humus. Laterite soils are often red in color from the iron oxides. If laterites are exposed to the Sun, they bake as hard as a brick. Q: What causes the red color of laterite soils? Choices: - oxygen - toxins - erosion - iron oxides A:
(Answer)
iron oxides
Ques: Answer the following question given this paragraph: When ancient plants underwent photosynthesis, they changed energy in sunlight to stored chemical energy in food. The plants used the food and so did the organisms that ate the plants. After the plants and other organisms died, their remains gradually changed to fossil fuels as they were covered and compressed by layers of sediments. Petroleum and natural gas formed from ocean organisms and are found together. Coal formed from giant tree ferns and other swamp plants. Q: During photosynthesis what organelle is used by plants to change sunlight into chemical energy? Choices: - mitochondria - golgi apparatus - ribosome - chloroplasts A:
Ans: chloroplasts

Answer the following question given this paragraph: Photosynthesis provides over 99% of the energy supply for life on Earth. A much smaller group of autotrophs - mostly bacteria in dark or low-oxygen environments - produce food using the chemical energy stored in inorganic molecules such as hydrogen sulfide, ammonia, or methane. While photosynthesis transforms light energy to chemical energy, this alternate method of making food transfers chemical energy from inorganic to organic molecules. It is therefore called chemosynthesis , and is characteristic of the tubeworms shown in Figure below . Some of the most recently discovered chemosynthetic bacteria inhabit deep ocean hot water vents or "black smokers. " There, they use the energy in gases from the Earth's interior to produce food for a variety of unique heterotrophs: giant tube worms, blind shrimp, giant white crabs, and armored snails. Some scientists think that chemosynthesis may support life below the surface of Mars, Jupiter's moon, Europa, and other planets as well. Ecosystems based on chemosynthesis may seem rare and exotic, but they too illustrate the absolute dependence of heterotrophs on autotrophs for food. Q: What process provides over 99% of the energy supply for life on earth? Choices: - gases - nutrients - Carbon - photosynthesis A:
(A).
photosynthesis
