Enzymes help us run.
What can happen to an enzyme if the temperature gets too high?
It can get bigger.
It can change color.
It can stop working.
It can become more active.
Why is it important to keep our bodies at a healthy temperature?
To help enzymes work properly.
To keep our skin warm.
To prevent us from getting sick.

What is diffusion?
Diffusion is when things move from a place where there's a lot of them to a place where there are fewer of them.
Diffusion is when cells use proteins to help move things across their membranes.
Diffusion is when water moves across a membrane from a place where there's more water to a place where there's less water.
Diffusion is when cells need help moving things across their membranes.
What is facilitated diffusion?
Facilitated diffusion is when cells use proteins to help move things across their membranes.
Facilitated diffusion is when water moves across a membrane from a place where there's more water to a place where there's less water.
Facilitated diffusion is when things move from a place where there's a lot of them to a place where there are fewer of them.
Facilitated diffusion is when cells need help moving things across their membranes.
Why is the cell membrane called selectively permeable?
It lets some things pass through easily, but not others.
It lets everything pass through easily.
It only lets water pass through.
It only lets small things pass through.
What is the cell membrane like?
A wall
A gatekeeper
A door
A window
What does active transport help the cell do?
Get rid of waste products
Maintain a stable internal environment
Bring in nutrients
All of the above
What happens to a cell if it loses too much water?
It grows bigger
It gets stronger
It shrinks and dies
It becomes more active
What are the two main types of cells?
Animal cells and plant cells
Prokaryotic cells and eukaryotic cells
Red blood cells and white blood cells
Muscle cells and nerve cells
What is the function of the nucleus in a eukaryotic cell?
It helps the cell move.
It stores the cell's DNA.
It produces energy for the cell.
It helps the cell communicate with other cells.
What is the function of the cell membrane?
The cell membrane helps the cell move.
The cell membrane helps the cell communicate with other cells.
The cell membrane is like a wall that keeps the inside of the cell separate from the outside.
The cell membrane produces energy for the cell.
What are the four important groups of molecules found inside a cell?
Carbohydrates, lipids, proteins, and nucleic acids
Sugars, fats, proteins, and DNA
Cell walls, cytoplasm, nucleus, and organelles
Energy, storage, building blocks, and instructions
What are the two types of nucleic acids?
DNA and RNA
Carbohydrates and lipids
Proteins and nucleic acids
Cell walls and cell membranes
What is one way that carbohydrates help plants?
They help plants store energy.
They help plants fight off disease.
They help plants build strong cell walls.
They help plants move water.
What does the circulatory system do?
The circulatory system helps animals breathe.
The circulatory system carries nutrients to all the cells in the body.
The circulatory system protects the body from germs.
The circulatory system helps animals move.
What are two ways the body protects itself from harm?
The immune system fights off germs and the skin protects the body from cuts.
The nervous system controls breathing and the skeletal system provides support.
The digestive system breaks down food and the circulatory system carries nutrients.
The body doesn't need protection from harm.
What is one way the skeletal system helps the body?
The skeletal system helps the body fight off germs.
The skeletal system helps the body digest food.
The skeletal system helps the body breathe.
The skeletal system provides support and structure for the body.
What do viruses need to make more of themselves?
They need to be in a warm place.
They need to be in a dark place.
They need to be inside a living thing.
They need to be in water.
What is a virus like when it gets inside your body?
A tiny bug that crawls around.
A thief who steals your stuff.
A helpful friend who cleans your house.
A seed that grows into a plant.
What is the main difference between a virus and a living thing?
Viruses are much smaller.
Viruses can't make more of themselves on their own.
Viruses don't have cells.
Viruses can't move.
