Answer the following question given this paragraph: The stored chemical energy in organic matter or wastes is called biomass energy. The organic matter may be trees or other plants, or it may be wastes from homes and industries. When biomass is burned, it produces thermal energy that can be used for heating homes, cooking, or generating electricity. Biomassespecially woodis an important energy source in the poorer nations where most people can't afford fossil fuels. However, burning biomass releases air pollution and contributes to global climate change. Biomass can be used to make ethanol, a fuel that is added to gasoline. Although ethanol releases less pollution than gasoline, large areas of land are needed to grow the plants needed to make it (see Figure below ). This reduces the amount of land available for food production. Q: What is the term that refers to stored chemical energy in organic matter or wastes? A:

OPTIONS:
- nuclear energy
- potential energy
- starch energy
- biomass energy

Answer: biomass energy

Problem: OPTIONS:
- carbon dioxide
- noble gas
- fossil compounds
- fossil fuels
Q: Answer the following question given this paragraph: Some of the pollutants from fossil fuels can be filtered out of exhaust before it is released into the air. Other pollutants can be changed to harmless compounds before they are released. Two widely used technologies are scrubbers and catalytic converters. Q: A catalytic converter filters pollutants in exhaust created by burning what before releasing it into the air? A:
Answer: fossil fuels

Problem:OPTIONS:
- known chromosomes
- risk chromosomes
- True Chromosomes
- linked chromosomes

Answer the following question given this paragraph: In anaphase I, the spindle fibers pull the linked chromosomes apart. The sister chromatids remain tightly bound together at the centromere. It is the chiasma connections that are broken in anaphase I as the fibers attached to the fused kinetochores pull the homologous chromosomes apart (Figure 7.5). In telophase I, the separated chromosomes arrive at opposite poles. The remainder of the typical telophase events may or may not occur depending on the species. In some organisms, the chromosomes decondense and nuclear envelopes form around the chromatids in telophase I. Cytokinesis, the physical separation of the cytoplasmic components into two daughter cells, occurs without reformation of the nuclei in other organisms. In nearly all species, cytokinesis separates the cell contents by either a cleavage furrow (in animals and some fungi), or a cell plate that will ultimately lead to formation of cell walls that separate the two daughter cells (in plants). At each pole, there is just one member of each pair of the homologous chromosomes, so only one full set of the chromosomes is present. This is why the cells are considered haploidthere is only one chromosome set, even though there are duplicate copies of the set because each homolog still consists of two sister chromatids that are still attached to each other. However, although the sister chromatids were once duplicates of the same chromosome, they are no longer identical at this stage because of crossovers. Q: Spindle fibers pull what apart in anaphase i? A:
****
A: linked chromosomes

Answer the following question given this paragraph: Segmented worms have a digestive system, nervous system, and circulatory system. Q: Segmented worms have a digestive,nervous and what type of system? A:
OPTIONS:
- pulmonary
- vascular
- lymphatic
- circulatory
circulatory

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

Answer: topple and break

input with options: Answer the following question given this paragraph: For the first 4 billion years of Earth history there is only a little evidence of life. Organisms were tiny and soft and did not fossilize well. But scientists use a variety of ways to figure out what this early life was like. Note that the period from Earth's origin to the beginning of the Phanerozoic is called the Precambrian. Q: What is the period from earth's origin to the beginning of the phanerozoic eon? A:
OPTIONS:
- Paleolithic
- Cenozoic
- anatolian
- precambrian
output:
precambrian
