Answer the following question given this paragraph: In science, a theory has been repeatedly shown to be true. A theory is supported by many observations. However, a theory may be disproved if conflicting data is discovered. Many important theories have been shown to be true by many observations and experiments and are extremely unlikely to be disproved. These include the theory of plate tectonics and the theory of evolution. Q: What does a theory need to be supported by? Choices: - facts - peer reviewed journals - scientists - many observations A:
many observations

Answer the following question given this paragraph: Farmers use greenhouses to extend the growing season. A greenhouse traps heat. Days that are too cool for a growing plant can be made to be just right. Similar to a greenhouse, greenhouse gases in the atmosphere keep Earth warm. Q: What do farmers use greenhouses for? Choices: - to predict the growing season - to allow the growing season - to decrease the growing season - to extend the growing season A:
(Answer)
to extend the growing season

Q: What sorts of collisions do not result in an overall loss of kinetic energy? Choices: - soft - static - powerful - elastic A:

Ans:elastic
