The Hierarchy of Life and Emergent Properties in Biological Systems

Mr. Anderson explains the hierarchy of life, from atoms to the biosphere, emphasizing emergent properties at each level. He uses termite colonies as an example of how systems exhibit new properties. The video covers biological organization from atoms, molecules, and cells to tissues, organs, and organ systems, concluding with populations, ecosystems, and the biosphere.

What is a key concept that appears at each level of the hierarchy of life?

• Emergent properties

• Photosynthesis

• Genetic mutation

• Cell division

How do termite cathedrals solve the problem of carbon dioxide buildup?

• By storing carbon dioxide

• Through natural ventilation

• By using photosynthesis

• By converting it to oxygen

What makes carbon atoms significant in biological molecules?

• They have six protons

• They are radioactive

• They can form four bonds

• They are the heaviest atoms

What is an emergent property of molecules?

• Ability to photosynthesize

• Radioactivity

• Magnetic properties

• Increased stability

Which of the following is NOT a type of macromolecule?
