Question

if you wanted to demonstrate homeostasis to a friend, you could use ______ as an example
a population changing over time.
environmental conditions holding constant through time.
cells having enough water to survive.
plants and animals needing energy sources.
an organism maintaining nearly constant internal conditions.

Explanation:

Homeostasis is the biological process where an organism regulates and maintains stable, nearly constant internal physiological conditions despite external changes. Let's analyze the options:

1. A population changing over time refers to evolution, not homeostasis.
2. Environmental conditions staying constant is about external stability, not an organism's internal regulation.
3. Cells having enough water is just one factor that homeostasis regulates, not the full definition of the process.
4. Needing energy sources is a basic requirement of life, not the regulatory process of homeostasis.
5. An organism maintaining nearly constant internal conditions directly matches the core definition of homeostasis.

Answer:

an organism maintaining nearly constant internal conditions.
