Ques:Answer the following question given this paragraph:   White blood cells are larger than red blood cells, but there are far fewer of them. Their role is to defend the body in various ways. For example, white blood cells called phagocytes engulf and destroy microorganisms and debris in the blood.   Q: Which blood cells serve to defend the body in various ways?   Choices:  - helper blood cells  - blue blood cells  - red blood cells  - white blood cells  A:

Ans:white blood cells

Ques:Answer the following question given this paragraph:   As you can see in Figure above , the electric and magnetic fields that make up an electromagnetic wave occur are at right angles to each other. Both fields are also at right angles to the direction that the wave travels. Therefore, an electromagnetic wave is a transverse wave.   Q: Because the fields that make up an electromagnetic wave are at right angles to each other and to the direction that the wave travels, an electromagnetic wave is considered what?   Choices:  - insverse wave  - transverse wave  - stimulation wave  - transverse wave  A:

Ans:transverse wave

Ques:Answer the following question given this paragraph:   Most substances have three distinct phases: gas, liquid, and solid. Phase changes among the various phases of matter depend on temperature and pressure. The existence of the three phases with respect to pressure and temperature can be described in a phase diagram. Two phases coexist (i. , they are in thermal equilibrium) at a set of pressures and temperatures. These are described as a line on a phase diagram. The three phases coexist at a single pressure and temperature. This is known as the triple point and is described by a single point on a phase diagram. A gas at a temperature below its boiling point is called a vapor. Vapor pressure is the pressure at which a gas coexists with its solid or liquid phase. Partial pressure is the pressure a gas would create if it existed alone. Dalton’s law states that the total pressure is the sum of the partial pressures of all of the gases present.   Q: Temperature and pressure affect changes in phases or states of what?   Choices:  - homeostasis  - decay  - energy  - matter  A:

Ans:
matter
