CEM 141 CHAPTER 1 LEARNING OBJECTIVES WITH COMPLETE SOLUTIONS Stable systems form when? The attractive forces and the repulsive forces are equal. Claim, evidence and reasoning for the existence of negatively charged particles in an atom. Claim: Electron's are negatively charged particles of an atom. Evidence: JJ's cathode ray. Electron's were ejected from the cathode, regardless of what the cathode was made of. Reasoning: Electrons must be negatively charged because they acceler...

CHAPTER 3 NEUROSCIENCE CHAPTER LEARNING OBJECTIVES 1. Understand the key methods that scientists use to learn about brain anatomy and functioning. • Neuroscientists examine autopsy tissue and patients with localized brain damage to learn about brain anatomy and brain function. • EEGs and neuroimaging, such as PET scans and fMRI, allow scientists to study brain function in the living brain. 2. Describe the two major types of cells in the nervous system and describe the prima...
