A scientist tests how temperature affects how fast sugar dissolves in water. She changes the temperature but accidentally uses different amounts of sugar in each trial.
What is the problem with this experiment?
Constants not kept the same
Why does water's solid form, ice, float when most substances in solid form are more dense and would sink?
Hydrogen bonds create a rigid, open structure, which spreads the molecules out
A mutation changes the structure of an enzyme in the body. What is the most likely result?
Unable to catalyze reactions in the body
What is the difference between predation and parasitism?
Parasitism keeps the host alive. Predation eats prey as a food source
