What is diffusion?

Diffusion is the movement of anything from a area of higher concentration to a area of lower concentration.

What is the hardest natural substance on Earth?

Diamond.

300

What causes diffusion?

Diffusion is caused by the constant random motion of particles.

300

What is the cells main office called?

Nucleus.

300

UCSB/University of South Carolina Beaufort.

300

At what temperature are Celsius and Fahrenheit equal?

-40°.

400

When will diffusion stop?

Diffusion will stop when the concentration gradient has been eliminated.

400

What does an organism have to do to have a metabolism?

Take in materials, use energy, give off waste.

400

What is cell transport?

The movement of a substance across the cell membrane.

400

What sport did Mr. Harlan play in school?

Swimming.

400

What does DNA stand for?

Deoxyribonucleic Acid.

500

Does higher temperature effect diffusion?

Yes higher temperature increases the random motion of molecules so that means higher is the rate of diffusion.
