100

The organelle known as the "powerhouse of the cell."

What is the mitochondrion?

100

You should always wear these to protect your eyes in a lab.

What are safety glasses?

100

The smallest unit of life.

What is a cell?

100

What is the purpose of a 'claim' in a scientific explanation?

What is to state an answer or conclusion based on the question or problem?

200

The system responsible for breaking down food into usable energy molecules. 

What is the digestive system?

200

These two molecules are required for cellular respiration to happen. 

What is glucose and oxygen?

200

Before leaving the lab, always do this with your hands.

What is wash them?

200

Cells that work together to perform the same function form this.

What is a tissue?

200

What counts as strong evidence in a lab report?

What is accurate, measurable data collected from an experiment?

300

This system removes carbon dioxide produced during cellular respiration.

What is the respiratory system?

300

Cellular respiration converts glucose into this usable form of energy.

What is ATP?

300

If glassware breaks, you should never pick it up with your bare hands. Instead, you should do this.

What is call and notify an adult/teacher?

300
Maintaining a stable internal environment despite external changes is called this.

What is homeostasis?

300

What does reasoning do in a CER paragraph?

What is it connects the evidence to the claim using scientific concepts?

400

These two systems work together to deliver oxygen to cells and remove carbon dioxide.

What are the respiratory and circulatory systems?

400

The chemical equation for cellular respiration is the reverse of this process.

What is photosynthesis? 

400

This is the first thing you should do if you spill a chemical.

What is tell the teacher immediately? 

400

Arrange the following in order from simplest to most complex: tissue, cell, organism, organ, organ system.

What is cell → tissue → organ → organ system → organism?

A student claims, 'Exercise increases heart rate to maintain homeostasis.' What reasoning supports this claim?

What is that a faster heart rate delivers more oxygen to cells for energy production?

500

Why does a runner’s breathing rate increase during intense exercise?

What is to supply more oxygen for ATP production and remove carbon dioxide faster?

500

Eating or drinking in the lab is not allowed because it could lead to this.

What is contamination or poisoning? 

500

Explain how the body uses negative feedback to regulate body temperature.

What is that sensors detect temperature changes and trigger responses (like sweating or shivering) to bring it back to normal?
