Power Plants
This green pigment absorbs sunlight in plant cells.
What is chlorophyll?
This type of plate boundary is responsible for creating mid-ocean ridges.
What is a divergent boundary?
This term describes the process where denser materials sank to Earth's center, forming layers.
What is differentiation?
A fossilized impression of a leaf or shell is an example of this type of fossil.
What is a cast fossil?
This type of fermentation is used to make bread rise and produces CO₂ gas.
What is alcoholic fermentation?
This is the specific location within the chloroplast where the light-dependent reactions occur.
What is the thylakoid membrane?
The Hawaiian Islands were formed by a stationary source of magma called this.
What is a hot spot?
The Miller-Urey experiment simulated lightning to produce these organic building blocks of proteins.
What are amino acids?
This type of dating gives a numerical age (in years) for a rock or fossil
What is absolute (or radiometric) dating?
This molecule is the final electron acceptor at the end of the Electron Transport Chain in aerobic respiration.
What is oxygen?
This 3-carbon molecule is the direct product of the Calvin Cycle before being assembled into glucose.
What is G3P (glyceraldehyde-3-phosphate)?
This plastic, flowing layer of the upper mantle allows the tectonic plates to move.
What is the asthenosphere?
This theory explains the origin of eukaryotic organelles like mitochondria from engulfed prokaryotes.
What is the Endosymbiotic Theory?
Geologists use these widely distributed, short-lived fossils to correlate rock layers across distances.
What are index fossils?
This is the primary advantage of fermentation for a cell, even though it yields little ATP.
What is it regenerates NAD⁺ so glycolysis can continue?
This crucial energy-carrying molecule is the main product of the Krebs (Citric Acid) Cycle.
What is NADH? (FADH2 also accepted)
This dense, metallic layer of Earth is responsible for generating the planet's magnetic field.
What is the outer core?
These layered fossil structures are some of the oldest evidence of life, formed by cyanobacteria.
What are stromatolites?
The principle that geologic processes occurring today operated the same way in the past is called this.
What is uniformitarianism?
Yeast would perform alcoholic fermentation, but your muscle cells perform this type when oxygen is low.
What is lactic acid fermentation?
This is the total number of ATP molecules produced (theoretically) from one molecule of glucose during aerobic cellular respiration.
What is 36 (or 38)?
This famous transform boundary in California is responsible for frequent earthquakes.
What is the San Andreas Fault?
The first major rise in atmospheric oxygen, which occurred about 2.4 billion years ago, is called this.
What is the Great Oxidation Event?
This rare, iridium-rich layer in rock strata is global evidence for the asteroid impact that killed the dinosaurs.
What is the K-Pg (Cretaceous-Paleogene) boundary?
This 3-carbon molecule is the end product of glycolysis, which then enters fermentation if no oxygen is present.
What is pyruvate?
