Emma is conducting an experiment to see how different amounts of light affect plant growth. She plants three identical seedlings in separate pots and places them under different light conditions: no light, partial light, and full sunlight. She measures the plants' heights every five days for 15 days.
Plant Growth in Different Light Conditions (cm)
Days | No Light | Partial Light | Full Sunlight |
0 | 2 cm | 2 cm | 2 cm |
5 | 2 cm | 5 cm | 7 cm |
10 | 2 cm | 8 cm | 12 cm |
15 | 2 cm | 11 cm | 16 cm |
Part A: Based on the data, which condition promotes the most plant growth?
Claim: Plants need sunlight to grow.

Carlos is researching the heart rates of different animals to understand how size affects heartbeats. He collects data on the heart rates of an elephant, a dog, a rabbit, and a hummingbird.
Data Table: Heart Rate of Different Animals
Animal | Heart Rate (beats per minute) |
Elephant | 30 |
Dog | 120 |
Rabbit | 205 |
Hummingbird | 1,260 |
Which of the following is true based on the data?
Claim: Smaller animals generally have faster heart rates than larger animals.

A group of scientists is studying how temperature affects the amount of oxygen in water. They collect water samples at different temperatures and measure the amount of dissolved oxygen.
Data Table: Dissolved Oxygen at Different Water Temperatures
Temperature (°C) | Dissolved Oxygen (mg/L) |
0 | 14.6 |
10 | 11.3 |
20 | 9.1 |
30 | 7.6 |
What happens to the amount of dissolved oxygen as the temperature increases?
Claim: Warmer water holds more oxygen than colder water.
