Re-read the first bullet, then answer it in a sentence 5. Repeat for each bullet 6. If the bullet asks for more that one answer be sure you have given the correct number The concentration of salt in water affects the hatching of brine shrimp eggs. Brine shrimp eggs will develop and hatch at room temperature in glass containers of salt solution. Describe a controlled experiment using three experimental groups that could be used to determine the best concentration of salt solution in which to hatch brine shrimp eggs. Your answer must include at least: • a description of how the control group and each of the three experimental groups will be different • two conditions that must be kept constant in the control group and the experimental groups data that should be collected
