Answer the following question given this paragraph: A combustion reaction occurs when a substance reacts quickly with oxygen (O 2 ). For example, in the Figure below , charcoal is combining with oxygen. Combustion is commonly called burning, and the substance that burns is usually referred to as fuel. The products of a complete combustion reaction include carbon dioxide (CO 2 ) and water vapor (H 2 O). The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is:. Q: What kind of a reaction occurs when a substance reacts quickly with oxygen? Choices: - invention reaction - Fluid Reaction - nitrogen reaction - combustion reaction A:
combustion reaction
Q: Answer the following question given this paragraph: An atom's mass number is its mass in atomic mass units (amu), which is about equal to the total number of protons and neutrons in the atom. Different isotopes of an element have different mass numbers because they have different numbers of neutrons. Q: Different isotopes of an element have different mass numbers because they have different numbers of what? Choices: - protons - electrons - nuclei - neutrons A:
A: neutrons
Question: Answer the following question given this paragraph: Cardiac muscle is found only in the walls of the heart. It is striated, or striped, because its muscle fibers are arranged in bundles. Contractions of cardiac muscle are involuntary. This means that they are not under conscious control. When cardiac muscle contracts, the heart beats and pumps blood. Q: When cardiac muscle contracts, the heart does what? Choices: - cardiac arrest - irregular heartbeat - heart murmur - pumps blood A:
Answer: pumps blood

Answer the following question given this paragraph: The Hubble space telescope shows that technology and science are closely related. Technology uses science to solve problems, and science uses technology to make new discoveries. However, technology and science have different goals. The goal of science is to answer questions and increase knowledge. The goal of technology is to find solutions to practical problems. Although they have different goals, science and technology work hand in hand, and each helps the other advance. Scientific knowledge is used to create new technologies such as the space telescope. New technologies often allow scientists to explore nature in new ways. Q: What is the goal of science? Choices: - improve knowledge - improve life expectancy - gain scholarships - increase knowledge A:
**Answer**
increase knowledge
