Q: 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? A:

OPTIONS:
- oxygen
- toxins
- erosion
- iron oxides

A: iron oxides

input: OPTIONS:
- mitochondria
- golgi apparatus
- ribosome
- chloroplasts Now, answer this question: 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? A:
A:
output: 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? A:

OPTIONS:
- gases
- nutrients
- Carbon
- photosynthesis

- platelets
- hemoglobin
- red blood cells
- white blood cells
Q: Answer the following question given this paragraph: Q: Inside each lymph node is a honeycomb of connective tissue with spaces filled by what? A:
Answer: white blood cells

Problem:OPTIONS:
- Fibrinolysis
- electrolysis
- glycolysis
- photosynthesis

Answer the following question given this paragraph: You could argue that oxygen is one of the most important, if not THE most important molecule necessary for life. However, oxygen is essentially just a waste product of the light reactions of photosynthesis. It is a "leftover" from a necessary part of the process. All the oxygen that is necessary to maintain most forms of life just happens to be released from the plant during this process. Q: Oxygen is essentially just a waste product of the light reactions of what? A:
****
A: photosynthesis

Problem:OPTIONS:
- nucleus
- cell
- DNA
- atom

Answer the following question given this paragraph: Following the discovery of the electron, J. J. Thomson developed what became known as the " plum pudding " model in 1904. Plum pudding is an English dessert similar to a blueberry muffin. In Thomson's plum pudding model of the atom, the electrons were embedded in a uniform sphere of positive charge like blueberries stuck into a muffin. The positive matter was thought to be jelly- like or a thick soup. The electrons were somewhat mobile. As they got closer to the outer portion of the atom, the positive charge in the region was greater than the neighboring negative charges and the electron would be pulled back more toward the center region of the atom. Q: Thomson's plum pudding model shows the structure of what? A:
****
A:
atom
