Answer the following question given this paragraph: work: A force is said to do work when it acts on a body so that there is a displacement of the point of application, however small, in the direction of the force. Thus a force does work when it results in movement. The work done by a constant force of magnitude on a point that moves a distance in the direction of the force is the product, . Q: What results when a force does work? Choices: - side effect - momentum - pressure - movement A:
movement

Answer the following question given this paragraph: In practice, chemical research is often not limited to just one of the five major disciplines. A particular chemist may use biochemistry to isolate a particular chemical found in the human body such as hemoglobin, the oxygen carrying component of red blood cells. He or she may then proceed to analyze the hemoglobin using methods that would pertain to the areas of physical or analytical chemistry. Many chemists specialize in areas that are combinations of the main disciplines, such as bioinorganic chemistry or physical organic chemistry. Q: What is the oxygen carrying component of red blood cells called? Choices: - molecule - mitochondria - platlet - hemoglobin A:
**Answer**
hemoglobin
