Scientific Investigation & Chemistry of Life
The variable you measure in an experiment.
What is the dependent variable?
The organelle known as the “powerhouse of the cell.”
What are mitochondria?
The way bacteria reproduce.
What is binary fission?
The shape of DNA.
What is a double helix?
The process where organisms with favorable traits survive and reproduce.
What is natural selection?
The reason controls are used in experiments.
What is to isolate the effect of the independent variable?
The structure that controls what enters and leaves the cell.
What is the cell membrane?
The reason viruses are considered non-living.
What is they cannot reproduce or metabolize without a host?
The base-pairing rules of DNA.
What is A with T and C with G?
The gradual change in ecosystems over time.
What is succession?
The property of water that makes it dissolve many substances.
What is polarity?
A feature found in plant cells but not animal cells.
What is a cell wall (or chloroplast/large vacuole)?
The structure that allows bacteria to move.
What is a flagellum?
The difference between genotype and phenotype
What is genotype is genetic makeup, phenotype is physical expression?
The maximum population size an environment can support.
What is carrying capacity?
The macromolecule that stores genetic information.
What are nucleic acids?
The process that moves molecules from high to low concentration without energy.
What is diffusion?
The way vaccines protect against viruses.
What is by stimulating the immune system to produce antibodies?
The scientist who developed binomial nomenclature.
Who is Carl Linnaeus?
A relationship where both species benefit.
What is mutualism?
This organic polymer is made up of small molecules called amino acids and functions to do work in cells.
What are proteins?
The organelle where photosynthesis takes place.
What are chloroplasts?
The type of virus that infects bacteria.
What is a bacteriophage?
The process by which DNA is copied before cell division.
What is DNA replication?
The type of growth pattern shown when a population grows rapidly without limits.
What is exponential growth?
