You place cockroaches in an experimental chamber which gives you complete control over temperature, relative humidity, and light. Throughout your experiment you keep temperature and relative humidity constant, but you vary light as follows: For the first 3 days, the lights go off at 6 PM each day and come one at 6 AM (a 12/12 light/dark cycle). From days 4-11, you then keep the cockroaches in constant darkness (0/24 light/dark) and you then restore the 12/12 light dark cycle starting on day 12. You measure the activity of the insects and indicate this using the gray bars shown in the graph below: During the 0L/12D period from days 4-11: a. the cockroaches are showing entrainment. b. the per gene in the optic lobes is inactive. c. the cockroaches are exhibiting free run. d. the cockroaches are exhibiting arhythmic activity. e. a and b f. c and darrow_forward

- A scientist at the University of Iowa uses a microscope to observe cells in the brain known as microglia. He makes observations about their structure, location, and activity. The scientist eventually observes the cells undergo a sudden and radical shift in their structure/shape and their motility (ability to move). He asks himself questions about what is causing this shift in behaviors and begins to design an experiment to determine the answer. Briefly describe how the scientist practiced both the exploration and testing aspects of scientific inquiry.arrow_forwardA common homeostatic regulatory mechanism involves an end product in a pathway generating an inhibitory effect on the upstream processes which stimulate its own production.
