Scientific method
The hypothesis
What is an explanation that can be tested.
What is determined by protons?
Covalent bond
What is the bond that allows elements to share electrons?
The main component of a plasma membrane
Phospholipids
Bateria do not have these.
What is the nucleus?
Independent variable
What is the change or what you are trying to test
What is the combination of neutrons and protons?
Ionic bond
What is the bond where elements take electrons from another element to make themselves stable.
These particles, water, oxygen gas can move into the cell by this process.
Simple diffusion
ATP is created
What are the mitochondria?
Dependent variable
What are the results, you have no control over these.
An ion
What is an atom that has either gained or lost an electron?
Hydrophobic
What is a molecule that repels water, for example fatty acid tails?
Solute
The plants use this for photosynthesis
Chloroplasts
Control
What you are comparing your test?
Polar molecule
What is a molecule that has a charge surrounding one of its elements, for example H2O has electrons spending more time around the oxygen because of the higher number of protons making that end of the molecule negative?
Solute
What is the smaller amount of something being placed into a larger amount for example, A spoonful of sugar being placed in a liter of water. Sugar is the solute.
If a red blood cell is placed in pure water the cell will experience
DNA is kept safe in this structure.
Nucleus
Graph axes
What has the x axes being the independent variable and the Y axes is the dependent value
Hydrogen bonding
What occurs when a hydrogen atom is attracted to a negative element of another molecule?
Ice formation
What is the structure created by water's unique bonds?
A solution that has a lower concentration of water outside of a cell is called
Hypertonic
These two structures are associated with each other to help interpret the DNA and make proteins
Rough Endoplasmic reticulum with the ribosomes
