Cells
The smallest unit of life.
A cell
The molecule that carries genetic information.
What is DNA
A living thing in an environment
What is an organism
Change in a population over time.
Evolution
The prefix “bio-” means this.
What is life
This structure is selectively permeable and controls what enters and leaves the cell
The cell membrane
A section of DNA that codes for a trait.
What is a gene
A group of the same species living in one area
What is a population
What is natural selection?
Traits that help survival are more likely to be passed on.
This term describes all living things.
What is Biotic
This type of cell is found in plants, animals, fungi, and protists.
a eukaryotic cell
A change in DNA that may or may not affect a trait.
What is a mutation
Where an organism lives
Habitat
Birds migrate into a new population and introduce new traits.
What is gene flow
The suffix “-logy” in “biology” means this.
The study of
Particles moving from high concentration to low concentration is this process.
Diffusion
Nonliving things are made of this
What is matter
Role/job in ecosystem
What is Niche
A flood randomly kills part of a population, changing traits by chance.
What is genetic drift
A student sees the word “anaerobic” and knows the prefix “an-” means “without.” This tells them the process happens this way.
What is without oxygen
Water moving across a membrane from high to low concentration is this process.
What is osmosis
What does DNA stand for?
deoxyribonucleic acid
A population of birds develops stronger beaks over time. What will MOST likely happen next in terms of ecology?
The population may increase if the trait helps survival
Bacteria become resistant to antibiotics over generations.
What is evolution by natural selection
A student has never seen the word “autotroph” but breaks it down: “auto” = self, “troph” = feeding. They conclude this organism does this.
What is makes its own food
