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? A:
OPTIONS:
- bisexually
- unisexually
- asexually
- sexually
sexually

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? A:
OPTIONS:
- similar
- asexual
- hormone
- sexual

Answer: sexual

Q: Answer the following question given this paragraph: A food chain is a simple diagram that shows one way energy flows through an ecosystem. You can see an example of a food chain in Figure below . Producers form the base of all food chains. The consumers that eat producers are called primary consumers. The consumers that eat primary consumers are secondary consumers. This chain can continue to multiple levels. Q: What term is used to describe a simple diagram that shows one way energy flows through an ecosystem? A:

OPTIONS:
- water cycle
- food pyramid
- fuel chain
- food chain

A: food chain

Answer the following question given this paragraph: Unlike a crystalline solid, an amorphous solid is a solid that lacks an ordered internal structure. Some examples of amorphous solids include rubber, plastic, and gels. Glass is a very important amorphous solid that is made by cooling a mixture of materials in such a way that it does not crystallize. Glass is sometimes referred to as a supercooled liquid rather than a solid. If you have ever watched a glassblower in action, you have noticed that he takes advantage of the fact that amorphous solids do not have a distinct melting point like crystalline solids do. Instead, as glass is heated, it slowly softens and can be shaped into all sorts of interesting forms. When a glass object shatters, it does so in a very irregular way, unlike crystalline solids, which always break into fragments that have the same shape as dictated by its crystal system. Q: Unlike a crystalline solid, an amorphous solid is a solid that lacks a what? A:
OPTIONS:
- atoms
- weight
- color
- ordered internal structure
ordered internal structure
