Answer the following question given this paragraph: Hemoglobin is an example of a transport protein in the blood. You can see how it works in Figure below . The heme parts of a hemoglobin molecule bind with oxygen. Each red blood cell has hundreds of hemoglobin molecules. This is how oxygen is carried in the blood to cells throughout the body. Q: The heme parts of a hemoglobin molecule bind with what element? A:

A: oxygen

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? A:
OPTIONS:
- motion
- light
- energy
- gravity
gravity

Q: Answer the following question given this paragraph: Most protists also have a complex life cycle. The life cycle of an organism is the cycle of phases it goes through until it returns to the starting phase. The protist life cycle includes both sexual and asexual reproduction. Why reproduce both ways? Each way has benefits. Asexual reproduction is fast. It allows rapid population growth when conditions are stable. Sexual reproduction increases genetic variation. This helps ensure that some organisms will survive if conditions change. Q: The protist life cycle benefits by including what forms of reproduction? A:
Answer:
asexual and sexual
