Answer the following question given this paragraph: An addition polymer is a polymer formed by chain addition reactions between monomers that contain a double bond. Molecules of ethene can polymerize with each other under the right conditions to form the polymer called polyethylene. Q: What is a polymer formed by chain addition reactions between monomers that contain a double bond called? Choices: - a linear polymer - a branched polymer - an addition monolayer - an addition polymer A:
an addition polymer
Answer the following question given this paragraph: A chemical reaction is a process that changes some chemical substances into others. It involves breaking and forming chemical bonds. Types of chemical reactions include synthesis reactions and decomposition reactions. Q: What is the name of the process that changes some chemical substances into others? Choices: - acid reaction - mixture - hypodermic reaction - chemical reaction A:
chemical reaction
Q: Answer the following question given this paragraph: Characteristics of Blood When you think about blood, the first characteristic that probably comes to mind is its color. Blood that has just taken up oxygen in the lungs is bright red, and blood that has released oxygen in the tissues is a more dusky red. This is because hemoglobin is a pigment that changes color, depending upon the degree of oxygen saturation. Blood is viscous and somewhat sticky to the touch. It has a viscosity approximately five times greater than water. Viscosity is a measure of a fluid's thickness or resistance to flow, and is influenced by the presence of the plasma proteins and formed elements within the blood. The viscosity of blood has a dramatic impact on blood pressure and flow. Consider the difference in flow between water and honey. The more viscous honey would demonstrate a greater resistance to flow than the less viscous water. The same principle applies to blood. The normal temperature of blood is slightly higher than normal body temperatureabout 38 C (or 100.4 F), compared to 37 C (or 98.6 F) for an internal body temperature reading, although daily variations of 0.5 C are normal. Although. Q: What is the term for the measure of a fluid's thickness? Choices: - friction - elasticity - salinity - viscosity A:
A: viscosity
Question: Answer the following question given this paragraph: This bottle of water models the semicircular canals in your ears. When you tip the bottle, the water moves up or down the sides of the bottle; when you tip your head, the liquid inside the semicircular canals moves up and down the sides of the canals. Tiny hair cells lining the canals sense the movement of liquid and send messages to the brain. Q: What senses the movement of liquid in ear canals? Choices: - Ear Drum - Brain Cells - muscle cells - hair cells A:
Answer: hair cells

Answer the following question given this paragraph: Velocity is defined as change in position over time. Can you see that would be the slope of this graph? (slope = rise over run and in this case the 'rise' is position and the 'run' is time). Find the instantaneous speed at sec. Q: What term refers to change in position over time? Choices: - Position Replacement - acceleration - Direction Replacement - velocity A:
**Answer**
velocity
