Answer the following question given this paragraph: Many animals have a relatively simple life cycle. A general animal life cycle is shown in Figure below . Most animals spend the majority of their life as diploid organisms. Just about all animals reproduce sexually. Diploid adults undergo meiosis to produce sperm or eggs. Fertilization occurs when a sperm and an egg fuse. The zygote that forms develops into an embryo. The embryo eventually develops into an adult. Q: What causes fertilization to occur? A:
OPTIONS:
- accumulation and an egg fuse
- tissue and an egg fuse
- genetic and an egg fuse
- sperm and an egg fuse
sperm and an egg fuse

Answer the following question given this paragraph: Transition-metal fluorides usually have higher oxidation states than their iodides. For a given metal, the lowest-oxidation-state oxide is basic and the highest-oxidation-state oxide is acidic. Halides of the transition metals become more covalent with increasing oxidation state and are more prone to hydrolysis. Propose a method to prepare each of the following compounds: TiCl 4[(CH3)2O]2, Na2TiO3, V2O5, and Na2Cr2O7. Of the group 5 elements, which. Q: Halides of the transition metals become more covalent with increasing oxidation state and are more prone to what? A:
OPTIONS:
- comproportionation
- cycloaddition
- decarbonylation
- hydrolysis

Answer: hydrolysis
