Answer the following question given this paragraph: Plants in the haploid generation are called gametophytes . They form from haploid spores. They have male and/or female reproductive organs and reproduce sexually. They produce haploid gametes by mitosis. Fertilization of gametes produces diploid zygotes. Zygotes develop into the diploid generation. Q: How do gametophyte plants form haploid gametes? A:

OPTIONS:
- during omniosis
- during after mitosis
- during after omniosis
- through mitosis

Answer: through mitosis

Answer the following question given this paragraph: The image above is of a copper plate that was made in 1893. The utensil has a great deal of elaborate decoration and the item is very useful. What would have happened if we decided that copper (I) chloride was just as good a material (well, it does have copper in it). The CuCl would end up as a powder when we pounded on it to shape it. Metals behave in unique ways. The bonding that occurs in a metal is responsible for its distinctive properties: luster, malleability, ductility, and excellent conductivity. Q: Luster, malleability, ductility, and conductivity are all properties of which kind of material? A:

OPTIONS:
- ores
- wood
- nonmetals
- metals

Answer: metals

Answer the following question given this paragraph: All living thingseven the simplest life formshave a complex chemistry. Living things consist of large, complex molecules, and they also undergo many complicated chemical changes to stay alive. Thousands (or more) of these chemical reactions occur in each cell at any given moment. Metabolism is the accumulated total of all the biochemical reactions occurring in a cell or organism. Complex chemistry is needed to carry out all the functions of life. Q: What is the accumulated total of all the biochemical reactions occurring in a cell or organism called? A:

OPTIONS:
- respiration
- expansion
- circulation
- metabolism

Answer: metabolism

OPTIONS:
- philosophical
- reactive
- symbolic
- analytical

Answer:
analytical
