Answer the following question given this paragraph: Physical science is the study of matter and energy. That covers a lot of territory because matter refers to all the "stuff" that exists in the universe. It includes everything you can see and many things that you cannot see, including the air around you. Energy is also universal. It's what gives matter the ability to move and change. Electricity, heat, and light are some of the forms that energy can take. Q: What branch of science is the study of matter and energy? Choices: - unnatural science - natural science - negative science - physical science A:
physical science
Answer the following question given this paragraph: Q: Under which conditions do many bacteria carry out alcohol fermentation? Choices: - melting - enzymatic - photosynthesis - anaerobic A:
anaerobic
Q: Answer the following question given this paragraph: Latitude is the distance north or south of the Equator. It's measured in degrees, from 0 to 90. Several climate factors vary with latitude. Q: What is used to measure, in degrees, the distance north or south of the equater? Choices: - elevation - equator - magnitude - latitude A:
A: latitude
Question: Answer the following question given this paragraph: A common method of producing charge in the lab is to rub cat or rabbit fur against stiff rubber, producing a negative charge on the rubber rod. If you hold a rubber rod on one end and rub only the tip of the other end with a fur, you will find that only the tip becomes charged. The electrons you add to the tip of the rod remain where you put them instead of moving around on the rod. Rubber is an insulator. Insulators are substances that do not allow electrons to move through them. Glass, dry wood, most plastics, cloth, and dry air are common insulators. Materials that allow electrons to flow freely are called conductors. Metals have at least one electron that can move around freely, and all metals are conductors. Q: Rubber is an example of what type of substances that do not allow electrons to move through them? Choices: - conductor - semi-conductor - solids - insulators A:
Answer: insulators

Answer the following question given this paragraph: When bread bakes, yeast releases carbon dioxide gas, forming the small holes in bread. The gas was produced by alcoholic fermentation carried out by yeast. Q: When bread bakes, yeast releases which gas? Choices: - carbon monoxide - oxygen - hydrogen - carbon dioxide A:
**Answer**
carbon dioxide
(Q).
Answer the following question given this paragraph: Plant Responses to Light Plants have a number of sophisticated uses for light that go far beyond their ability to photosynthesize low-molecularweight sugars using only carbon dioxide, light, and water. Photomorphogenesis is the growth and development of plants in response to light. It allows plants to optimize their use of light and space. Photoperiodism is the ability to use light to track time. Plants can tell the time of day and time of year by sensing and using various wavelengths of sunlight. Phototropism is a directional response that allows plants to grow towards, or even away from, light. The sensing of light in the environment is important to plants; it can be crucial for competition and survival. The response of plants to light is mediated by different photoreceptors, which are comprised of a protein covalently bonded to a lightabsorbing pigment called a chromophore. Together, the two are called a chromoprotein. Q: Plants can tell the time of day and time of year by sensing and using various wavelengths of what Choices: - moisture - lunar cycles - precipitation - sunlight A:
(A).
sunlight
