Answer the following question given this paragraph: An example of a chemical reaction is the burning of methane. In this chemical reaction, the reactants are methane (CH 4 ) and oxygen (O 2 ), and the products are carbon dioxide (CO 2 ) and water (H 2 O). A chemical reaction involves the breaking and forming of chemical bonds. When methane burns, bonds break in the methane and oxygen molecules, and new bonds form in the molecules of carbon dioxide and water. Q: Burning of methane is a type of what, which involves the breaking and forming of bonds? Choices: - liquid reaction - physical reaction - toxic reaction - chemical reaction A:
chemical reaction

Question: Answer the following question given this paragraph: Hormones are the messenger molecules of the endocrine system. Endocrine hormones travel throughout the body in the blood. However, each hormone affects only certain cells, called target cells. A target cell is the type of cell on which a hormone has an effect. A target cell is affected by a particular hormone because it has receptor proteins that are specific to that hormone. A hormone travels through the bloodstream until it finds a target cell with a matching receptor it can bind to. When the hormone binds to a receptor, it causes a change within the cell. Exactly how this works depends on whether the hormone is a steroid hormone or a non-steroid hormone . At the link below, you can watch an animation that shows how both types of hormones work. http://www. wisc-online. com/objects/ViewObject. aspx?ID=AP13704. Q: What are the messenger molecules of the endocrine system? Choices: - neurons - enzymes - acids - hormones A:
Answer: hormones
