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
200
I am a group 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 group
200
I can carry out photosynthesis and respiration
What is a plant cell
200
Name two systems that work together to help you move
What is 

Nervous

Muscular

Skeletal

200
We work together to help an organism maintain homeostasis
What are organ systems
200

I am a skin cell with a mutation, who will inherit this mutation from me?

skin cells that reproduce from me through mitosis

300
I am the way you improve your experiement
What is repeat it several times?
300
I help make cells more visible 
What is a microscope
300

name at least ONE reproductive hormone.

What is testosterone, estrogen, progesterone, LH, FSH

300

How do hormones help maintain homeostasis? 

they can indicate and trigger our bodies to start particular functions that manage homeostatis: feeling of hunger, feeling of fear or stress. 

300
I am a molecule that controls the traits in your body
What is DNA
400
Without me, you won't know if your results are due to the change you made to your IV, or just some other factor. You need at least 3 - 5 for an experiment to be valid. I stay the same for all groups
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

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 messenger between DNA and the Ribosome
What is RNA
500

True or False and Explain

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
I am the movement of substances across a membrane without energy.
What is diffusion or passive transport
500
Provide two similar jobs of an organelle and an organ system
What is circulatory and cytoplasm; skin and cell membrane; nervous and nucleus (more)
500
I am a disease that attacks your immune system (AIDS). Describe why a person with AIDS would not be able to live a normal life?
they can't fight infections and die because of simple things like the common cold
500
I am the organ that helps the fetus get nutrients from the mother
What is the placenta
