Describe the difference between mitosis and meiosis (type of reproduction, number of daughters and number of chromosomes.)
Mitosis is asexual reproduction that produces two daughters with the same chromosomes. Meiosis is sexual reproduction that produces four daughters with half the number of chromosomes.
Looking at a pot of boiling water, where is the conduction, radiation and convection?
Conduction: pot touching the hot stove top
Radiation: heat waves coming off the top of the boiling water
Convection: the boiling water moving - heat rises and cold sinks

Describe the difference between replication and repetition.
Replication is another scientist completing your experiment to check if it's accurate. Repetition is doing multiple trials in your own experiment to make sure your results are consistent.
