100
Transpiration and respiration move this molecule in and out of the atmosphere
What is water
100
This is often called the "power house" of the cell
What is the mitochondria
100
This atom is used to build the backbone of life's molecules
What is carbon
100
This is the final electron acceptor in aerobic respiration
What is oxygen
100
This part of an experiment serves as the basis for comparison
What is the control
200
Respiration and decay are two major processes in the recycling of this element
What is carbon
200
This organelle is responsible for capturing energy from light
What is the chloroplast
200
These six elements make up the majority of life's molecules
What is C,H,O,N,P,S
200
This is the net gain of ATP in glycolysis
What is two
200
This is the part of an experiment expected to produce a change
What is the independent variable
300
This is the only ecological cycle that does not involve the atmosphere
What is the phosphorus cycle
300
This organelle found in all cells is needed for protein production
What is the ribosome
300
This is a protein that changes the rate of a chemical reaction. Usually lowering it.
What is an enzyme
300
This is the waste product of photosynthesis
What is oxygen
300
This part of an experiment is a measurable change
What is the dependent variable
400
Legumes are important in ecological cycling because they transform this element
What is nitrogen
400
This organelle maintains homeostasis in all cells
What is the plasma membrane
400
This type of bond forms molecules by sharing electrons
What is a covalent bond
400
In aerobic respiration, this cycle must turn twice to break down one glucose molecule
What is the Kreb's cycle (citric acid cycle)
400
This is the name given to a proposed solution to a scientific problem
What is a hypothesis
500
The principle that states "No two species can occupy the same niche at the same time" is this
What is the principle of competitive exclusion
500
This structure is circular in prokaryotic cells and rod shaped in eukaryotic cells
What is a chromosome
500
This class of molecules is able to store potential energy on a short term basis (relatively)
What is carbohydrates
500
These two organelles are related by the processes of photosynthesis and respiration
What is chloroplast and mitochondria
500
This is the number of independent variables that can be tested in one experiment
