I am a prediction that can be tested by an experiment. I include the independent and dependent variables.
I am never written as a statement.
What is a Hypothesis.
100
I have a cell wall, a large permanent vacuole and chloroplasts
What is a plant cell
100
I control the entry of oxygen and the exit of carbon dioxide from your body
What is the respiratory system
100
We work together to help a cell maintain homeostasis
What are organelles
100
I am quick and don't require a lot of energy, but all my offspring are genetically identical to me which can put them at risk for disease.
What is asexual reproduction

I am a variable that is needed so you know if your experimental variable had an effect. You compare your results of your experimental group to me.
What is the control variable or control group
200
I can carry out photosynthesis and respiration
What is a plant cell

Name two systems that work together and describe their function
What is (mixed answers will apply)
200
We work together to help an organism maintain homeostasis
What are organ systems

What is three times

You need at least 3 - 5 for an experiment to be valid.
What is a constant
400
I control the movement of substances into and out of the cell based on size and concentration
What is the cell membrane
400
to break down and absorb nutrients through the microvilli
why do we need a digestive system
400
I happen to your body when you fail to maintain homeostasis
What is disease or death
400
I am the process that allows evolution to occur
What is natural selection
500
when your hypothesis is not supported, you can just change it to suit the results of your experiment.
What is False; you should to repeat the experiment and/or create new research questions to follow up with
500
When you take me from a water solution to a salt solution and then move me into a distilled water solution, my membrane will go from this...to this.
What is shrink and then swell
500
Provide two analogous jobs of an organelle and an organ system
