Properties of Life

What are the fundamental properties that characterize all living things?

Order, Sensitivity/Response to the Environment, Reproduction, Adaptation, Growth & Development, Regulation/Homeostasis, Energy Processing, and Evolution.

What does 'Order' refer to in the context of living things?

It refers to the highly structured organization of living things, ranging from molecules to organs, including intricate patterns and colors.

How do organisms demonstrate 'Sensitivity/Response to the Environment'?

Organisms respond to internal and external cues, such as cells dividing in response to signals or a sunflower tracking the sun (heliotropism).

What is an example of homeostasis in humans?

The ability of insulin to regulate blood sugar levels.

What is the significance of 'Reproduction' in living organisms?

It ensures the continuity of life by allowing organisms to produce offspring and pass traits from one generation to the next.

What is meant by 'Adaptation' in the context of evolution?

Beneficial traits evolve over generations, helping organisms survive in their environment, although not all evolution leads to adaptation.

Provide an example of adaptation in animals.

Rabbits developing longer ears over generations in a hot climate.

What does 'Growth & Development' entail in multicellular organisms?

It involves increasing cell numbers and specialization of cells, leading to the emergence of new characteristics.

What is 'Regulation/Homeostasis' in living organisms?

Actions that maintain an organism's internal balance, such as regulating body temperature within a normal range.

How do living things engage in 'Energy Processing'?

They convert energy from one form to another to power their activities, such as breaking down an acorn to produce ATP.

What is 'Evolution' in biological terms?

Changes in DNA sequences over time that lead to changes in traits across generations, driven by mutation, natural selection, and genetic drift.
