The Scientific Method
This is a possible explanation for what is being studied. It is tested by experimental observations.
What is a hypothesis?
This word describes the starting materials in a chemical reaction.
What are reactants?
The building block of this biomolecule is the monosaccharide.
What is a carbohydrate?
This common cause of diseases is not alive because it is not able to reproduce itself.
What is a virus?
What is plasma membrane?
This would be the dependent variable in an experiment in which a drug is tested to see how well it helps people who suffer from allergies.
What is the increase or decrease in symptoms of the people who take the drug?
This is the type of compound that includes carbon bonded to hydrogen, and also often other elements like oxygen or nitrogen.
This type of biomolecule contains different examples, but the thing they all have in common is that they are nonpolar, and for this reason do not dissolve in water.
What are lipids?
These are made in the ribosomes.
What are proteins?
This process is the reason why when a skunk sprays its odor into the air, and eventually people down the block will smell it.
What is simple diffusion?
This is a quality that a hypothesis might have. It means that it is possible to find out if the hypothesis is correct by doing an experiment.
What is testable?
The atomic number of an atom that has 7 protons, 7 neutrons, and 7 electrons.
What is 7?
This is the word for the building blocks of DNA.
What is nucleotide?
The main job of this organelle is making lipids.
What is the smooth Endoplasmic Reticulum? (Smooth ER)
This is the process by which cells respond to changes in water concentration naturally, without using energy.
What is osmosis?
This is the process by which scientific research is scrutinized by other scientists to make sure it is valid.
What is peer review?
This type of bond is sometimes described as giving or taking electrons, or as an attraction between positive and negatively charged atoms.
What is an ionic bond?
This is the type of bond that is responsible for the secondary folding of proteins, in which alpha helixes or beta sheets are formed.
What is hydrogen bonding?
This type of cell has no nucleus.
What is a prokaryotic cell?
If a cell is put in this type of solution, water moves into the cell, causing it to grow.
What is hypotonic?
This would be a possible hypothesis for a hydroponics experiment to find out how plants would grow under conditions of 24 hours of light.
What is: Plants will grow badly if they get 24 hours of light, because they will photosynthesize too much but not grow enough.
This is what the pH scale measures.
What is the concentration of hydrogen ions in a solution?
This is the number of amino acids that exist.
What is 20?
The theory that says organelles like mitochondria and chloroplasts were once independent prokaryotic organisms, and they became parts of the cell through the process of evolution.
What is endosymbiotic theory?
This is the process when a protein on the outside of a cell recognizes something, and then the membrane folds around it and brings it in.
What is receptor-mediated endocytosis?
