Answer the following question given this paragraph: There are two basic types of cells, prokaryotic cells and eukaryotic cells . The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus . The nucleus is where cells store their DNA , which is the genetic material. The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus. Instead, their DNA floats around inside the cell. Organisms with prokaryotic cells are called prokaryotes . All prokaryotes are single-celled (unicellular) organisms. Bacteria and Archaea are the only prokaryotes. Organisms with eukaryotic cells are called eukaryotes . Animals, plants, fungi, and protists are eukaryotes. All multicellular organisms are eukaryotes. Eukaryotes may also be single-celled. Q: What is the main difference between eukaryotic and prokaryotic cells? Choices: - prokaryotic cells have a nucleus - eukaryotic cells have a flagella - eukaryotic cells have a cell wall - eukaryotic cells have a nucleus A:
eukaryotic cells have a nucleus
Answer the following question given this paragraph: Selective precipitation can also be used in qualitative analysis. In this method, reagents are added to an unknown chemical mixture in order to induce precipitation. Certain reagents cause specific ions to precipitate out; therefore, the addition of the reagent can be used to determine whether the ion is present in the solution. Q: In qualitative analysis, reagents are added to an unknown chemical mixture in order to induce what? Choices: - motion - sunlight - erosion - precipitation A:
precipitation
Q: Answer the following question given this paragraph: Photoautotrophs are cells that capture light energy, and use carbon dioxide as their carbon source. There are many photoautotrophic prokaryotes, which include cyanobacteria. Photoautotrophic prokaryotes use similar compounds to those of plants to trap light energy. Q: What type of cells capture light energy, and use carbon dioxide as their carbon source? Choices: - sporozoans - blood cells - chloroplasts - photoautotrophs A:
A: photoautotrophs
Question: Answer the following question given this paragraph: The same agents that erode landscapes also erode soil. They are water, wind, ice, or gravity. Running water is the leading cause of soil erosion. Water is abundant and has a lot of power. Wind is also a leading cause of soil erosion. Wind can pick up soil and blow it far away. Q: What is the leading cause of soil erosion? Choices: - tidal winds - volcanic explosions - glacier movement - running water A:
Answer: running water

Answer the following question given this paragraph: Ungulates include hoofed animals, such as deer, sheep, goats, pigs, buffalo, elephants and giraffes ( Figure below ). These mammals use their hoofs to sustain their whole body weight while moving. Hoofs are formed by a thick nail rolled around the tip of the toe. Q: In the mammal family, what is the name for hoofed animals, such as deer, sheep, goats, pigs, buffalo, elephants and giraffes? Choices: - primates - bovines - rodents - ungulates A:
(A).
ungulates
