Question

donita performed an experiment to study the effect of temperature on the cellular respiration of crickets. she placed the same number of similarly - sized crickets in seven different containers. she closed the containers and exposed each to a different temperature for 30 minutes. at the end of this time period, she recorded the level of carbon dioxide (co₂) in each container. the table below shows donitas results.

sample group	temperature (°c)	co₂ concentration (ppm)
2	10	408
3	15	412
4	20	423
5	25	438
6	30	455
7	35	472

based on the data, what is the relationship between temperature and the cellular respiration of crickets?

• as temperature rises, cellular respiration stops.
• as temperature rises, the rate of cellular respiration is constant.
• as temperature rises, the rate of cellular respiration increases.
• as temperature rises, the rate of cellular respiration decreases.

Explanation:

To determine the relationship, we analyze the data: as temperature (in °C) increases from 5 to 35, CO₂ concentration (a measure of cellular respiration rate) increases (402 to 472 ppm). This shows that higher temperature correlates with a higher respiration rate. The first option is wrong (respiration doesn't stop), the second (constant rate) is wrong (values increase), and the fourth (decrease) is wrong (values rise). So the correct relationship is that as temperature rises, the rate of cellular respiration increases.

Answer:

As temperature rises, the rate of cellular respiration increases. (The option corresponding to this statement in the multiple - choice, e.g., if it's the third option, then "C. As temperature rises, the rate of cellular respiration increases.")
