input with options: Answer the following question given this paragraph: Phylum Nemertea The Nemertea are colloquially known as ribbon worms. Most species of phylum Nemertea are marine, predominantly benthic or bottom dwellers, with an estimated 900 species known. However, nemertini have been recorded in freshwater and terrestrial habitats as well. Most nemerteans are carnivores, feeding on worms, clams, and crustaceans. Some species are scavengers, and some nemertini species, like Malacobdella grossa, have also evolved commensalistic relationships with some mollusks. Some species have devastated commercial fishing of clams and crabs. Nemerteans have almost no predators and two species are sold as fish bait. Morphology Ribbon worms vary in size from 1 cm to several meters. They show bilateral symmetry and remarkable contractile properties. Because of their contractility, they can change their morphological presentation in response to environmental cues. Animals in phylum Nemertea show a flattened morphology, that is, they are flat from front to back, like a flattened tube. Nemertea are soft and unsegmented animals (Figure 28.18). Q: The colloquial term "ribbon worm" refers to the mostly marine species of what phylum? A:
OPTIONS:
- nematoida
- lophophorata
- gnathifera
- nemertea
output: nemertea

Q: Answer the following question given this paragraph: Acids can be classified as monoprotic or polyprotic based on the number of acidic hydrogens they contain. Q: What can be classified as monoprotic or polyprotic based on the number of acidic hydrogens they contain? A:

OPTIONS:
- ions
- cations
- salts
- acids

A: acids

input: OPTIONS:
- liquid propane
- water
- carbon
- oil Now, answer this question: Answer the following question given this paragraph: Yes, we will use up all our gasoline eventually. Gasoline is derived from oil. Oil deposits were formed over hundreds of millions of years. They cannot be quickly replenished. Oil is an example of a nonrenewable resource. Q: Gasoline is derived from which other liquid? A:
A:
output: oil

Answer the following question given this paragraph: Food chains carry energy from producers (autotrophs) to consumers (heterotrophs). 99% of energy for life comes from the sun via photosynthesis. Note that only nutrients recycle. Energy must continue to flow into the system. Though this food chains "ends" with decomposers, do decomposers, in fact, digest matter from each level of the food chain? (See the Energy Transfer: Decomposers (Advanced) concept). Q: Food chains carry energy from what group to what group? A:

OPTIONS:
- consumers to producers
- decomposers to producers
- refiners to consumers
- producers to consumers

Answer: producers to consumers

Problem: OPTIONS:
- einstein
- newton
- darwin
- galileo
Q: Answer the following question given this paragraph: Humans have been making and using magnifying lenses for thousands of years. The term "telescope" was coined by the Italian scientist and mathematician Galileo Galilei (15641642). Galileo built the first telescope in 1608. His telescope used two lenses to make distant objects appear both nearer and larger. He subsequently made many improvements to telescope design. Q: Which scientist built the first telescope? A:
Answer: galileo

Answer the following question given this paragraph: Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements. The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive. Because alkali metals are so reactive, they are found in nature only in combination with other elements. They often combine with group 17 elements, which are very "eager" to gain an electron. At the URL below, you can watch a video that shows just how reactive the alkali metals are. Q: Because alkali metals are so reactive, they are found in nature only in ________ with other elements? A:

OPTIONS:
- isolation
- cooperation
- competition
- combination

Answer:
combination
