Question: Answer the following question given this paragraph: The above example shows how science generally advances. New evidence is usually used to improve earlier ideas rather than entirely replace them. In this way, scientists gradually refine their ideas and increase our understanding of the world. On the other hand, sometimes science advances in big leaps. This has happened when a scientist came up with a completely new way of looking at things. For example, Albert Einstein came up with a new view of gravity. He said it was really just a dent in the fabric of space and time. Q: Representing a leap in scientific understanding, einstein described what as a dent in the fabric of space and time? Choices: - motion - light - energy - gravity A:
Answer: gravity

Answer the following question given this paragraph: Motility The majority of protists are motile, but different types of protists have evolved varied modes of movement (Figure 23.8). Some protists have one or more flagella, which they rotate or whip. Others are covered in rows or tufts of tiny cilia that they coordinately beat to swim. Still others form cytoplasmic extensions called pseudopodia anywhere on the cell, anchor the pseudopodia to a substrate, and pull themselves forward. Some protists can move toward or away from a stimulus, a movement referred to as taxis. Movement toward light, termed phototaxis, is accomplished by coupling their locomotion strategy with a light-sensing organ. Q: What is the term for movement toward light? Choices: - phototropism - gravitational pull - autolysis - phototaxis A:
**Answer**
phototaxis

Answer the following question given this paragraph: Fossil fuels are made from plants and animals that lived hundreds of millions of years ago. The plants and animals died. Their remains settled onto the ground and at the bottom of the sea. Layer upon layer of organic material was laid down. Eventually, the layers were buried very deeply. They experienced intense heat and pressure. Over millions of years, the organic material turned into fossil fuels. Q: Fossil fuels are made out of what two objects? Choices: - gases and animals - plants and water - soil and animals - plants and animals A:
**Answer**
plants and animals
