The Scientific Method
These are the reactants of the chemical reaction:
C3H8 + 5O2 → 4H2O + 3CO2 + energy
What are C3H8 and O2?
This is the characteristic of sugar that makes it able to dissolve in water.
What is hydrophilic?
This type of cells does not contain membrane-bound organelles.
What are prokaryotic cells?
What is passive transport?
This type of reasoning is when you make a conclusion based on observations.
What is inductive reasoning?
Add this to a solution with a pH of 8, to change the pH to 3.
What is an acid?
One example of this biomolecule is stored inside the nucleus of eukaryotic cells, and another example travels from the nucleus to the ribosomes to help make proteins.
What is nucleic acid?
This word describes the tails of a phospholipid because they do not dissolve in water.
What is hydrophobic?
This is what happens to water when a cell is placed in a hypertonic solution.
What is moves out of the cell?
This is a relationship or connection between 2 things. It should not be confused with causation.
What is correlation?
The atomic number of nitrogen, an element that has 7 protons, 7 neutrons, and 7 electrons.
What is 7?
What is protein?
The organelle where cellular respiration happens, so the cell can get energy in the form of ATP.
What is the mitochondria?
This word describes the fact that cell membranes only allow certain substances to pass through it.
What is semipermeable, or selectively permeable?
This is what you call the group of people who receive an empty pill with no medicine in it.
What is the control group, or placebo?
The pH scale measured the concentration of this ion in water.
What is a hydrogen ion?
This category of biomolecule is hydrophobic.
What is lipid?
The organelle that manufactures steroid hormones, a type of lipid.
What is the endoplasmic reticulum?
This is the process in which a vesicle is formed outside of the cell to fold a solution into the cell.
What is pinocytosis?
In the bat experiment, this was the independent variable.
What is contact with the fungus?
This pH represents a solution that has 1,000,000 times higher concentration of hydrogen ions than a solution of pH 7.
What is pH 1?
This is the building block of carbohydrates.
What is a monosaccharide?
A theory that says that some of the organelles in eukaryotic cells originated in free-living prokayotes.
What is endosymbiotic theory?
Soak carrot sticks in this kind of solution, and they will be crisp and crunchy the next day.
What is a hypotonic solution?
