This "brain" of the cell contains the genetic material (DNA) and acts as the control center for all activities.

What is the nucleus?


100

This system works with the skeletal system to allow your body to move.

What is the muscular system?

100

In this state of matter, particles are packed tightly together and only vibrate in place.

What is a solid?

100

This type of heat transfer requires direct contact between two objects

What is conduction?

100

When light waves hit a black t-shirt, the energy is taken in by the fabric, which is known as this.

What is absorption?

200

All _________________ are made of cells.

What is a living thing (organism)?

200

Your respiratory system brings in oxygen, but this system is responsible for "trucking" that oxygen to the rest of your body.

What is the circulatory system?

200

When you add enough thermal energy to a liquid, it undergoes this specific phase change to become a gas.

What is evaporation or vaporization?

200

You feel the warmth of a campfire even without touching the flames because of this type of energy transfer that travels in waves.

What is radiation?

200

This wave behavior explains why a pencil looks "broken" when you put it in a glass of water.

What is refraction?

300

This thin, flexible outer layer acts like a "security guard," controlling what enters and exits the cell.

What is the cell membrane?

300

This term describes the body’s ability to maintain a stable internal environment, like keeping your temperature at 37°C.

What is homeostasis?

300

This state of matter has no definite shape and no definite volume; its particles fly around freely to fill any space.

What is a gas?

300

This type of heat transfer occurs through fluids (liquids or gases) when warm material rises and cool material sinks.

What is convection?

300

If a material allows light to pass through it clearly so that you can see objects on the other side, it is described as this.

What is transparent?

400

While animal cells are floppy, plant cells have this rigid outer structure that provides support and protection.

What is the cell wall?

400

A stimulus that the nervous system receives will be followed by a ___________.

What is a response?

400

This is the temperature at which a solid gains enough energy to turn into a liquid.

What is the melting point?

400

Materials like wood, plastic, or air that do not allow heat to pass through them easily are called this.

What are insulators?

400

Sound waves require this (like air, water, or steel) to travel through, whereas light waves do not.

What is a medium/matter?

500

This is the level of organization that describes a group of similar cells working together to perform a specific function

What is tissue?

500

These specialized cells in your eyes, ears, and skin pick up information from the environment and send it to your brain.

What are sensory receptors?

500

This is a measurement of how often the particles within a substance collide with the container they are in.

What is pressure?

500

If you put a room-temperature spoon into hot soup, the heat will stop moving when the spoon and soup reach this.

What is thermal equilibrium?
500

This type of material, like wax paper, allows some light through but scatters it so you can't see clearly.

What is translucent?
