Homeostasis Storyline Review

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

How does carbon dioxide contribute to global warming?

Back

Carbon dioxide traps heat in the atmosphere, leading to an increase in global temperatures.

Front

What happens to cells in a hypertonic solution?

Back

Cells lose water and shrink, a process known as crenation.

Front

What is the role of photosynthesis in energy conversion?

Back

Photosynthesis converts light energy into chemical energy stored in glucose.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

Define biotic factors in an ecosystem.

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms.

Front

What are abiotic factors?

Back

Abiotic factors are the non-living components of an ecosystem, including sunlight, water, temperature, and soil.

Front

Explain osmosis.

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the significance of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis, helping to reduce atmospheric CO2 levels.
