🔬 Biology Basics
The study of living things.
What is biology?
The organelle that controls what enters and leaves the cell.
What is the cell membrane?
The molecule that stores genetic information.
What is DNA?
All the living and nonliving factors in an environment.
What is an ecosystem?
The variable a scientist purposely changes.
What is the independent variable?
The smallest unit that can be considered alive.
What is a cell?
The organelle that contains DNA in most eukaryotic cells.
What is the nucleus?
A section of DNA that contains instructions for a trait or protein.
What is a gene?
An organism that makes its own food.
What is a producer?
The variable a scientist measures.
What is the dependent variable?
A scientist observes frogs becoming less active as temperatures drop. What factor are they investigating?
What is temperature?
A cell has many mitochondria. What does this suggest about the cell?
What is high energy demand?
Two parents pass genetic information to their child. What process explains this?
What is inheritance?
A hawk eats a mouse. What role does the hawk have?
What is a consumer?
A student tests whether different amounts of fertilizer affect plant growth. What should stay the same between groups?
What are the controls?
A living thing maintains a stable internal environment despite outside changes. (we do this)
What is homeostasis?
A cell placed in a salty solution loses water and shrinks. What process caused this?
What is osmosis?
Two siblings have different traits even though they have the same parents. Why?
What is genetic variation?
A population of insects becomes resistant to a pesticide over many generations. What process explains this?
What is natural selection?
A scientist repeats an experiment several times and gets similar results. Why is this useful?
What is reliability?
A student says, “Plants aren't alive because they don't move.” What characteristic of life disproves this?
What is metabolism/growth?
A cell needs to move a substance from low concentration to high concentration. What does it need?
What is energy/ATP?
A DNA change occurs in a gene. What is this change called?
What is a mutation?
A forest loses most of its trees. Years later, plants and animals return. What ecological process is occurring?
What is succession?
In biology, succession (or ecological succession) is the gradual process by which the mix of species and habitat in an area changes over time.
A student says, “My experiment proves my hypothesis is always true.” What is wrong with this conclusion?
What is one experiment cannot prove it universally?
