Answer the following question given this paragraph: Figure 15.2 All animals that derive energy from food are heterotrophs. The (a) black bear is an omnivore, eating both plants and animals. The (b) heartworm Dirofilaria immitis is a parasite that derives energy from its hosts. It spends its larval stage in mosquitos and its adult stage infesting the hearts of dogs and other mammals, as shown here. (credit a: modification of work by USDA Forest Service; credit b: modification of work by Clyde Robinson). Q: All animals that derive energy from food are classified as what? A:
OPTIONS:
- lifeforms
- paleotrophs
- heliotrophs
- heterotrophs

Answer: heterotrophs

Question: Answer the following question given this paragraph: Longer chains of monosaccharides are referred to as polysaccharides . Starch, glycogen, and cellulose are three extremely common polysaccharides made entirely out of glucose molecules. The differences lie in the types of bonds between the glucose units and the extent of branching in the carbohydrate chain. Starch is found in plants and is consumed as part of our diet. Glycogen is made by the body and is a storage form of glucose for when the cells need extra energy. Cellulose is another long-chain polysaccharide found in plants. Unlike starch and glycogen, the human body cannot break cellulose down into molecules of glucose. Although cellulose does not have any nutritional value in terms of calories, it is a major component of dietary fiber, which has other digestive benefits. Q: What is the term for longer chains of monosaccharides ? A:
OPTIONS:
- proteins
- hydrocarbons
- oligosaccharides
- polysaccharides
Answer: polysaccharides

input with options: Answer the following question given this paragraph: CHAPTER SUMMARY 45.1 Population Demography Populations are individuals of a species that live in a particular habitat. Ecologists measure characteristics of populations: size, density, dispersion pattern, age structure, and sex ratio. Life tables are useful to calculate life expectancies of individual population members. Survivorship curves show the number of individuals surviving at each age interval plotted versus time. Q: What is the term for individuals of a species that live in a particular habitat? A:
OPTIONS:
- family
- ecosystem
- biosphere
- population
output: population

Q: Answer the following question given this paragraph: Flammability is the ability of matter to burn. When matter burns, it combines with oxygen and changes to different substances. Wood is an example of flammable matter, as seen in Figure below . Q: What term is used to describe the ability of matter to burn? A:

OPTIONS:
- permeability
- reactivity
- volatility
- flammability

A: flammability

input: OPTIONS:
- antennae
- cilia
- fin
- flagella Now, answer this question: Answer the following question given this paragraph: Sponges are characterized by a feeding system unique among animals. As sponges don't have mouths, they must feed by some other method. Sponges have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter food from the water as the water is pumped through the body and out other larger openings. The flow of water through the sponge is unidirectional, driven by the beating of flagella, which line the surface of chambers connected by a series of canals. Q: The flow of water through the sponge is unidirectional, driven by the beating of what? A:
A:
output: flagella

Question: Answer the following question given this paragraph: In grazing , the predator eats part of the prey but does not usually kill it. You may have seen cows grazing on grass. The grass they eat grows back, so there is no real effect on the population. In the ocean, kelp (a type of seaweed) can regrow after being eaten by fish. Q: In grazing, a predator partially eats but does not kill what? A:
OPTIONS:
- time
- pack
- predators
- prey
Answer:
prey
