Cell Biology
The semipermeable gatekeeper that regulates what enters the cell.
Cell membrane
The specific organelle containing thylakoids where light reactions occur.
Chloroplast.
A species that has a disproportionately large effect on its natural environment.
Keystone species.
The variable that is measured or observed in response to a change.
Dependent variable.
A logical conclusion based on an observation and prior knowledge.
Inference.
The organelle that modifies, sorts, and packages proteins for secretion.
Golgi apparatus or body.
The sugar molecule produced during the Calvin Cycle.
Glucose.
This process occurs when life returns to an area that already has soil, like a forest regrowing after a major fire.
Secondary succession.
A statement based on repeated experimental observations that describes an aspect of the universe.
Scientific Law.
The total magnification if the eyepiece lens is 10x and the objective lens is 40x.
400x
[TRIPLE JEOPARDY - $900] Explain how the folded membrane of the mitochondria relates to its function.
Increased surface area for more ATP production.
The energy-carrying molecule that recharges during cellular respiration.
ATP (Adenosine Triphosphate).
An organism that cannot produce its own food and must eat other organisms.
Consumer or heterotroph.
When a scientist's expectations or preferences influence the results of an experiment.
Bias.
The process of using a standard scale to determine the dimensions or mass of an object.
Measurement or Calibration.
These organelles contain enzymes that break down waste and cellular debris.
Lysosomes.
The byproduct of photosynthesis that is a required reactant for respiration.
Oxygen.
[TRIPLE JEOPARDY - $1200] Contrast point source and non-point source pollution with one example of each.
Point being pipe or factory versus non-point being city runoff or fertilizer.
A trial where all variables are kept constant except for the one being tested.
Controlled experiment.
The scientist who first observed animalcules under a handcrafted microscope.
Anton van Leeuwenhoek.
The theory stating that all living things are made of cells and cells come from pre-existing cells.
The Cell Theory.
The Law of Conservation of Mass states that this must happen to atoms during a chemical reaction.
Atoms are rearranged, not created or destroyed.
The symbiotic relationship where one organism benefits and the other is neither harmed nor helped.
Commensalism.
The degree to which an experimental result matches the accepted value.
Accuracy (versus Precision).
The difference between a theory and a law in terms of "why vs. what."
Law describes the "what", theory describes the "why".
