Thinking Like A Scientist #1

Questions: 15 | Attempts: 161 | Last updated: Aug 22, 2025

Sample Question
Jane Goodall spent countless hours among the chimpanzees doing scientific research. In her research, Jane learned that chimpanzees use stems or long blades of grass as tools to “fish” out a tasty meal from termite mounds. How did Jane learn this about the chimpanzees? This qualitative research is based on Jane following the chimpanzees, taking notes and making careful _______________

Observations

Positive and Negative Feedback Loop Quiz

Questions: 5 | Attempts: 9602 | Last updated: Mar 22, 2025

Sample Question
If blood glucose levels fall below normal levels (for instance, during the post-absorptive or fasting state, when nutrients from a recently digested meal are no longer circulating in the blood, or during starvation), insulin secretion is inhibited and, at the same time, the alpha cells of the pancreas respond by secreting glucagon, a hormone that has several important effects: (1) it accelerates the breakdown of glycogen to glucose in liver and skeletal muscle cells; (2) it increases the breakdown of fats to fatty acids and glycerol in adipose tissue and, consequently, the release of these substances into the blood (which cells can thus use for energy); and (3) it stimulates liver cells to increase glucose synthesis (from glycerol absorbed from the blood) and glucose release into the blood. These effects collectively cause an increase in blood glucose levels back to normal levels.

This is a positive feedback loop

This is a negative feedback loop

This is not a feedback loop
