Multiple choice questions about enzymes, Earth's atmosphere, and cellular transport.
Understand the Problem
The image contains three multiple-choice questions related to biology. The first question is about enzyme activity in thermophilic bacteria, based on a provided graph. The second question concerns the changes in Earth's atmosphere over time. The third question asks to identify a type of cellular transport based on a visual representation.
Answer
1. C, 2. C, 3. A
The answers are:
- C. An enzyme functions best under specific temperature conditions.
- C. Photosynthesis by cyanobacteria
- A. Active transport, because energy is being used to move molecules against the concentration gradient
Answer for screen readers
The answers are:
- C. An enzyme functions best under specific temperature conditions.
- C. Photosynthesis by cyanobacteria
- A. Active transport, because energy is being used to move molecules against the concentration gradient
More Information
Enzymes have optimal temperatures, photosynthesis oxygenated the atmosphere, and active transport requires energy to move molecules against their concentration gradient.
Tips
Carefully review the graphs and diagrams provided in similar questions.
