Identify the independent, dependent, and constant variables for different experiments. A biologist tests different lighting conditions for bacteria. She uses the same number of the same strain of bacteria on each petri dish, with the same type and amount of growing medium on each. Each petri dish is subjected to a different amount of light for a 24-hour period. After this time, the biologist counts the number of bacteria on each petri dish.

its been noted for the past decade or so that there is some (approximately 5% to 7%) shrinkage in the brains of people who have schizophrenia, most notably in the gray matter, which is an important part structures in the brain’s amygdala, hippocampus and parahippocampus, which are all involved in memory storage and retrieval memory storage and retrieval.
