input: OPTIONS:
- heat
- movement
- fission
- fusion Now, answer this question: Answer the following question given this paragraph: In a red supergiant, fusion does not stop. Lighter atoms fuse into heavier atoms. Eventually iron atoms form. When there is nothing left to fuse, the star's iron core explodes violently. This is called a supernova explosion. The incredible energy released fuses heavy atoms together. Gold, silver, uranium and the other heavy elements can only form in a supernova explosion. A supernova can shine as brightly as an entire galaxy, but only for a short time, as shown in Figure below . Q: What always continues in a red supergiant? A:
A:
output: fusion

Answer the following question given this paragraph: Scientists also have to "check their work. " The results of an investigation are not likely to be well accepted unless the investigation is repeatedusually many timesand the same result is always obtained. Getting the same result when an experiment is repeated is called replication . If research results can be replicated, it means they are more likely to be correct. Repeated replication of investigations may turn a hypothesis into a theory. On the other hand, if results cannot be replicated they are likely to be incorrect. Q: Getting the same result when an experiment is repeated is called what? A:

OPTIONS:
- mutation
- initiation
- repetition
- replication

Answer: replication

Problem: OPTIONS:
- electrolysis fuel
- polymerization fuel
- nuclear fue
- hydrocarbon fuel
Q: Answer the following question given this paragraph: It is hard to overstate the importance of hydrocarbons to modern life. Hydrocarbons have even been called the "driving force of western civilization. " You saw some ways they are used in the opening image. Several other ways are pictured in the Figure below . The most important use of hydrocarbons is for fuel. Gasoline, natural gas, fuel oil, diesel fuel, jet fuel, coal, kerosene, and propane are just some of the commonly used hydrocarbon fuels. Hydrocarbons are also used to make things, including plastics and synthetic fabrics such as polyester. Q: Gasoline, natural gas, fuel oil, diesel fuel, jet fuel, coal, kerosene, and propane are examples of what type of fule? A:
Answer: hydrocarbon fuel

Problem:OPTIONS:
- foolish
- mixed
- pressure
- conditioning

Answer the following question given this paragraph: Conditioning is a way of learning that involves a reward or punishment. If you ever trained a dog to obey a command, you probably gave the dog a tasty treat each time he performed the desired behavior. It may not have been very long before the dog would reliably follow the command in order to get the treat. This is an example of conditioning that involves a reward. Q: The way of learning that involves reward and punishment is called? A:
****
A: conditioning

OPTIONS:
- viruses
- yeast
- algae
- bacteria
bacteria

Answer the following question given this paragraph: 4.3 | Connective Tissue Supports and Protects By the end of this section, you will be able to: Identify and distinguish between the types of connective tissue: proper, supportive, and fluid Explain the functions of connective tissues As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. The matrix plays a major role in the functioning of this tissue. The major component of the matrix is a ground substance often crisscrossed by protein fibers. This ground substance is usually a fluid, but it can also be mineralized and solid, as in bones. Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of amorphous ground substance, and protein fibers. The amount and structure of each component correlates with the function of the tissue, from the rigid ground substance in bones supporting the body to the inclusion of specialized cells; for example, a phagocytic cell that engulfs pathogens and also rids tissue of cellular debris. Q: Connective tissues typically have three characteristic components in common: cells, large amounts of amorphous ground substance, and what else? A:
OPTIONS:
- antioxidants
- hormones
- white blood cells
- protein fibers

Answer:
protein fibers
