PRACTICE IN IDENTIFYING VARIABLES Identify the independent variable and dependent variable(s) in the following
experiments.
1. A researcher was interested in the effects of reward on intrinsic motivation. Some
children were told that they would be given a special award for drawing with magic
markers (an activity they already enjoyed) Other children were simply asked to draw
with the magic markers. One week later, the children were unobtrusively observed for
how much time they spent drawing with the markers. The children who expected and
received a reward for drawing with the markers were less likely to draw with them later

Describe pasteur’s results and how they disprove spontaneous generation.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.

In which of the following relationships is one organism always benefited while the other organism is always harmed
