AP Bio History of Life on Earth Video 4

Stanley Miller boiled ammonia, methane, and hydrogen for a few days and discovered amino acids had assembled. Why do you think he chose those 3 ingredients?

• He wanted to create a new type of fuel.
• He was testing the effects of high temperatures on metals.
• He aimed to produce a new form of energy.
• He aimed to simulate early Earth conditions to explore the origins of life.

Should AP Bio Students already know this "checklist of life"? If you don't know it, what should you do?

(Mrs. Grimm)

• Yes, AP Bio students should know it. If not, they should study relevant materials.
• Only students planning to take the exam need to know it.
• They should ignore it and focus on other topics.
• No, AP Bio students do not need to know it.

Schrodinger's explanation of life- organisms maintain a state of negative entropy- is related to homeostasis. Which of the following is the best definition of homeostasis?

• The ability of an organism to evolve over time.
• The process of cellular respiration in organisms.
• The interaction of organisms with their environment.
• The maintenance of a stable internal environment in an organism.

Pay attention to this next part. You will learn all about it in November/December (really difficult concept) when we discuss Cellular Respiration.

• Photosynthesis
• Cellular Respiration
• Fermentation
• Cell Division
