What is your hypothetical research question? (Must include population of study, independent variable-with at least two levels, one dependent variable-some type of measure or score, experimental and control groups).Turn your research question into a null and alternate hypothesis. What is the best way to collect data and minimize sample bias? How are you going to collect information to choose the best representative sample?What ethical considerations should be made with the study you proposed to ensure that your experiment would conform to the scientific community’s expectations of ethical research?

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
