Something that stays the same to keep an experiment fair
What is a constant
A macromolecule used as a source of immediate energy

I am doing a test to see if there is a connection between how long you run and how fast your heart beats. I will be performing an experiment where a person will run for a 1 minute and I will check their heartbeat. Then they will run for 2 minutes and I will check their heart rate. I will do this up to 6 minutes and see if there is a connection. What do you think my hypothesis should be?
What is...If I increase the amount of time I run, then my heartbeat will increase.
What property of water makes it beneficial for the Earth's climate stability that the Earth is mostly made of water?
What is high specific heat
If a solution is 80% water and 20% salt is placed in a beaker with 24% salt. What direction will the water move? What type of solution is this?
Hypertonic, water will move out.
2 differences between mitosis and meiosis
What is 1 v 2 divisions, no crossing over vs crossing over, makes 2 identical diploid somatic cells vs 4 unique haploid gametes cells
Purines is the name used to describe nitrogen bases that have how many rings?
What is 2 rings (big base)
