Answer the following question given this paragraph: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). Q: Warming up your body before a workout does what to the blood flow? Choices: - reduces it - stops it - minimizes it - increases it A:
increases it
Q: Answer the following question given this paragraph: Inductive reasoning involves reaching conclusions about unobserved things on the basis of what has already been observed. Induction is used regularly in fields such as archaeology, where inferences about the past from present are made. Inductions could also be made across outer space, as in astronomy, where conclusions about the whole universe are drawn from the limited number of observations we are able to make. Q: Reaching conclusions about unobserved things on the basis of what has already been observed is known as what kind of reasoning? Choices: - primitive - reductive - conductive - inductive A:
A: inductive
Question: Answer the following question given this paragraph: Mucous membranes provide a mechanical barrier at body openings. They also line the respiratory, GI, urinary, and reproductive tracts. Mucous membranes secrete mucus , a slimy substance that traps pathogens. The membranes also have hair-like cilia. The cilia sweep mucus and pathogens toward body openings where they can be removed from the body. When you sneeze or cough, pathogens are removed from the nose and throat (see Figure below ). Tears wash pathogens from the eyes, and urine flushes pathogens out of the urinary tract. You can watch the sweeping action of cilia at the following link: http://mcdb. colorado. edu/courses/2115/units/Other/mucus%20animation. swf . Q: The tiny hair present on mucus membranes is known as? Choices: - tissue - collagen - dendrites - cilia A:
Answer: cilia

When an elastic material is stretched or compressed, it exerts elastic force. This force increases the more the material is stretched or compressed. Q: Elasticity is the ability of a material to return to its original shape after being stretched or? Choices: - combustion - Contained - correlated - compressed A:
**Answer**
compressed
