You want to study how slapping students, without them expecting it, can affect their mile time in PE. Before your PE class starts, you slap every student who walks into PE class. Then you record the time it takes to complete their mile run and compare it to their older mile time. You found that the harder you slapped students, the bigger the improvement in their mile times (r = +0.93).-What is the dependent and independent variable?-How is the dependent variable operationally defined?-Explain how the parasympathetic response is involved in this study. -Does this research prove causation? Why or why not?

Which group’s rights—human participants or nonhuman animals—are the most important to protect? why? not really a right or wrong answer, but give a detailed explanation

1) earth's crust is made up of relatively rigid plates that ride atop earth's hot, semiliquid mantle. (2) the plates are called tectonic because they're in constant motion. (3) they can move because earth's mantle is a very hot and semiliquid fluid called magma. (4) volcanoes are a result of magma rising up or erupting through a plate, particularly where plate boundaries are moving against each other. (5) also, when plates slide against each other, causing friction along adjacent plate boundaries, earthquakes frequently occur. (6) therefore, we often find volcanoes and earthquakes along plate boundaries. (7) plates may also collide. (8) when that happens, mountain ranges are formed. (9) for example, the collision of the plate carrying the indian subcontinent created the himalayan mountains when it collided with the asian plate. 2. which sentence in this passage introduces a new topic that might begin a new paragraph? a. sentence 5 b. sentence 4 c. sentence 7 d. sentence 6
