Answer the following question given this paragraph: Chemical cells are found in batteries. They produce voltage by means of chemical reactions. A chemical cell has two electrodes, which are strips made of different materials, such as zinc and carbon (see Figure below ). The electrodes are suspended in an electrolyte. An electrolyte is a substance containing free ions that can carry electric current. The electrolyte may be either a paste, in which case the cell is called a dry cell, or a liquid, in which case the cell is called a wet cell. Flashlight batteries contain dry cells. Car batteries contain wet cells. Animations at the URL below show how batteries work. Q: Batteries produce voltage through what type of reaction? A:

OPTIONS:
- magnetic
- radiation
- thermal
- chemical

Answer: chemical

Problem: OPTIONS:
- propellants
- complexes
- Starters
- reactants
Q: Answer the following question given this paragraph: Like equations in math, equations in chemistry must balance. There must be the same number of each type of atom in the products as there is in the reactants. In equation 1, count the number of hydrogen and oxygen atoms on each side of the arrow. There are two hydrogen atoms in both reactants and products. There are two oxygen atoms in the reactants but only one in the product. Therefore, equation 1 is not balanced. Q: What do you call the atomic "ingredients" that go into a chemical reaction? A:
Answer: reactants

Problem:OPTIONS:
- cyst
- inflammation
- edema
- tumor

Answer the following question given this paragraph: In panel A, an abnormal cell (2) is prevented from dividing, and the abnormal cell dies (1). In panel B, an abnormal cell is not prevented from dividing. Instead, it divides uncontrollably, leading to the formation of a tumor. Q: If an abnormal cell is not prevented from dividing and it divides uncontrollably, what forms? A:
****
A: tumor

Answer the following question given this paragraph: The male reproductive system consists of structures that produce sperm and secrete testosterone. They include the penis, testes, and epididymes. Q: The penis, testes and epididymes are structures in what male anatomical system? A:
OPTIONS:
- endocrine
- protective
- immune
- reproductive
reproductive
