Answer the following question given this paragraph: Compounds form when atoms of different elements combine. This process is a chemical reaction. Q: In which type of reaction are compounds formed? Choices: - gaseous reaction - acid reaction - balanced reaction - chemical reaction A:
chemical reaction
Answer the following question given this paragraph: The average kinetic energy of atoms (each of mass and average speed ) in a gas is related to the temperature of the gas, measured in Kelvin. The Boltzmann constant is a constant of nature, equal to. Q: What are molecules that the immune system recognize as foreign to the body? Choices: - viruses - peptides - tumors - antigens A:
antigens
Q: Answer the following question given this paragraph: Vertebrates reproduce sexually, and almost all of them have separate male and female sexes. Generally, aquatic species have external fertilization, whereas terrestrial species have internal fertilization. Can you think of a reason why aquatic and terrestrial vertebrates differ in this way?. Q: In which way do vertebrates reproduce? Choices: - bisexually - unisexually - asexually - sexually A:
A: sexually
Question: Answer the following question given this paragraph: The lifecycle of basidiomycetes includes alternation of generations (Figure 24.16). Spores are generally produced through sexual reproduction, rather than asexual reproduction. The club-shaped basidium carries spores called basidiospores. In the basidium, nuclei of two different mating strains fuse (karyogamy), giving rise to a diploid zygote that then undergoes meiosis. The haploid nuclei migrate into basidiospores, which germinate and generate monokaryotic hyphae. The mycelium that results is called a primary mycelium. Mycelia of different mating strains can combine and produce a secondary mycelium that contains haploid nuclei of two different mating strains. This is the dikaryotic stage of the basidiomyces lifecyle and and it is the dominant stage. Eventually, the secondary mycelium generates a basidiocarp, which is a fruiting body that protrudes from the groundthis is what we think of as a mushroom. The basidiocarp bears the developing basidia on the gills under its cap. Q: Spores are generally produced through what type of reproduction? Choices: - similar - asexual - hormone - sexual A:
Answer: sexual

negatively charged electrons
Q: Answer the following question given this paragraph: Cell division is just one stage of the cell cycle. The cell cycle includes all of the stages in the life of a cell. The cell cycle is more complex in eukaryotic than prokaryotic cells. Q: What stages in the life of a cell does the cell cycle include? Choices: - adult stages - intermediate stages - both - all A:
A: all
