Chemistry of Life
This macromolecule is the main energy source for cells.
What are carbohydrates?
Follow-up: Example?
The molecule that stores genetic information.
What is DNA?
Cell division producing identical cells.
What is mitosis?
Linear energy flow in ecosystem.
What is a food chain?
A sudden environmental event (like a wildfire or hurricane) that affects populations regardless of size.
What is a density-independent factor?
This organelle produces ATP through cellular respiration.
What is the mitochondria?
This molecule carries instructions from DNA to ribosomes.
What is mRNA?
Cell division that produces gametes.
What is meiosis?
Percent of energy passed to next level.
What is 10%?
This evolutionary process causes individuals with advantageous traits to survive and reproduce more successfully.
What is natural selection?
Movement of molecules from high to low concentration without energy.
What is diffusion?
The process of making RNA from DNA.
What is transcription?
Process where better traits help survival and reproduction.
What is natural selection?
Both species benefit interaction.
What is mutualism?
This survivorship curve is typical of humans and elephants, where most individuals live to old age before dying.
What is a Type I survivorship curve?
Organelle that modifies, packages, and ships proteins.
What is the Golgi apparatus?
DNA → RNA → protein flow of information.
What is the central dogma?
Differences in DNA among individuals.
What is genetic variation?
Species with big ecosystem impact despite low numbers.
What is a keystone species?
Name each of these

This process uses sunlight to convert carbon dioxide into glucose.
What is photosynthesis?
A change in the DNA sequence.
What is a mutation?
Barrier preventing fertilization.
What is a prezygotic barrier?
Population levels off due to limits.
What is carrying capacity?
This type of pathogen can be transmitted between animals and humans, often jumping from wildlife or livestock to people.
What is a zoonotic pathogen?
