Answer the following question given this paragraph: Producers are organisms that produce food for themselves and other organisms. They use energy and simple inorganic molecules to make organic compounds. The stability of producers is vital to ecosystems because all organisms need organic molecules. Producers are also called autotrophs . There are two basic types of autotrophs: photoautotrophs and chemoautotrophs. Q: Photoautotrophs and chemoautotrophs are two basic types of what? A:

OPTIONS:
- plants
- consumers
- decomposers
- autotrophs

Answer: autotrophs

Problem: OPTIONS:
- zeta point
- tipping point
- chromatic point
- end point
Q: Answer the following question given this paragraph: AcidBase Titrations Because most common acids and bases are not intensely colored, a small amount of an acid base indicator is usually added to detect the equivalence point in an acidbase titration. The point in the titration at which an indicator changes color is called theendpoint. The procedure is illustrated in Example 21. Q: The point in the titration at which an indicator changes color is called what? A:
Answer: end point

Problem:OPTIONS:
- fiberglass
- cellophane
- foil
- mylar

Answer the following question given this paragraph: times faster than air. For this reason, high-quality helium-filled balloons are usually made of Mylar, a dense, strong, opaque material with a high molecular mass that forms films that have many fewer pores than rubber. Mylar balloons can retain their helium for days. Q: What material used for helium-filled balloons is dense, strong and opaque, with a high molecular mass that forms films that have many fewer pores than rubber? A:
****
A: mylar

Answer the following question given this paragraph: Gram-negative bacteria have a cell wall made of peptidoglycan, whereas Gram-positive bacteria have a cell wall made of lipoteichoic acid. Figure 22.19 Which of the following statements about the nitrogen cycle is false? a. Nitrogen fixing bacteria exist on the root nodules of legumes and in the soil. Denitrifying bacteria convert nitrates (NO3-) into nitrogen gas (N2). Ammonification is the process by which ammonium ion (NH4+) is released from decomposing organic compounds. Nitrification is the process by which nitrites (NO2-) are converted to ammonium ion (NH4+). Q: Gram-negative bacteria have a cell wall made of peptidoglycan, whereas gram-positive bacteria have a cell wall made of what? A:
OPTIONS:
- choanocyte acid
- solmization acid
- hydrolic acid
- lipoteichoic acid
lipoteichoic acid

Answer the following question given this paragraph: All chemical reactions involve energy. Some chemical reactions consume energy, whereas other chemical reactions release energy. Chemical reactions can be either spontaneous, which do not require an input of energy, or non-spontaneous, which does require an input of some type of energy. Energy may be in the form of heat, light or electricity. Each of the energy changes that occur during a reaction are graphed in Figure below . In the reaction on the left, energy is released. In the reaction on the right, energy is consumed. Q: What types of energy is released during a chemical reaction? A:
OPTIONS:
- human, magnetic, electrical
- temperature , electricity , light
- magnetism, electricity, light
- heat, electricity, light

Answer: heat, electricity, light

input with options: Answer the following question given this paragraph: Both flukes and tapeworms are parasites with vertebrate hosts, including human hosts. Flukes live in the host's circulatory system or liver. Tapeworms live in the host's digestive system. Usually, more than one type of host is required to complete the parasite's life cycle. Look at the life cycle of the liver fluke in Figure below . As an adult, the fluke has a vertebrate host. As a larva, it has an invertebrate host. If you follow the life cycle, you can see how each host becomes infected so the fluke can continue its life cycle. Q: Both flukes and tapeworms are parasites with what kind of host? A:
OPTIONS:
- insect
- trees
- cells
- vertebrate
output:
vertebrate
