Answer the following question given this paragraph: Fish were the first vertebrates to evolve. The earliest fish lived in the water, and modern fish are still aquatic. Q: What were the first vertebrates to evolve? Choices: - snail - trees - shark - fish A:
fish
Q: Answer the following question given this paragraph: Virtually all living things use glucose for energy, but glucose is just one of many examples of biochemical compounds that are found in most or all living things. In fact the similarity in biochemical compounds between living things provides some of the best evidence for the evolution of species from common ancestors. A classic example is the biochemical compound called cytochrome c. It is found in all living organisms because it performs essential life functions. Only slight variations in the molecule exist between closely related species, as you can see in the Figure below . The molecule is identical in humans and their closest relatives, the chimpanzees. And even between humans and the single-celled tetrahymena (pictured in the Figure below ), the cytochrome c molecule is nearly 50 percent the same. Q: Similarity in biochemicals, like the glucose used by virtually all living things for energy, provides evidence of what? Choices: - gravity - variation - DNA - evolution A:
A: evolution
Question: Answer the following question given this paragraph: Centrioles are organelles that are found only in animal cells. They are located near the nucleus. They help organize the DNA in the nucleus before cell division takes place. They ensure that the DNA divides correctly when the cell divides. Q: What term is used to describe organelles that are found only in animal cells? Choices: - anticlines - fibrils - acids - centrioles A:
Answer: centrioles

Answer the following question given this paragraph: Meiosis is a special type of cell division. It produces haploid daughter cells. It occurs when an organism makes gametes. Meiosis is basically mitosis times two. The original diploid cell divides twice. The first time is called meiosis I. The second time is called meiosis II. However, the DNA replicates only once. It replicates before meiosis I but not before meiosis II. This results in four haploid daughter cells. Q: What type of cells does meiosis produce? Choices: - child cells - diploid daughter cells - mutated cells - haploid daughter cells A:
**Answer**
haploid daughter cells
Q: Answer the following question given this paragraph: A catalyst is a substance that increases the rate of a chemical reaction. The presence of a catalyst is one of several factors that influence the rate of chemical reactions. (Other factors include the temperature, concentration, and surface area of reactants. ) A catalyst isn't a reactant in the chemical reaction it speeds up. As a result, it isn't changed or used up in the reaction, so it can go on to catalyze many more reactions. Q: A catalyst can increase the rate of what, in general? Choices: - mechanicl reaction - carbon reaction - consumption reaction - chemical reaction A:
A: chemical reaction
