What is the effect of increasing temperature on the heart rate of frogs and humans?

Heart rate decreases

Heart rate increases

Increasing temperature generally leads to an increase in heart rate for both frogs and humans. This phenomenon is associated with the physiological responses to higher temperatures, where the metabolic processes become more active.

In ectothermic animals like frogs, their heart rate is directly influenced by ambient temperature; warmer temperatures enhance the speed of enzymatic reactions and metabolic activities, leading to a faster heart rate.

In humans, while they are endothermic and maintain a relatively constant body temperature, an increase in ambient temperature can lead to an increase in heart rate as part of the body's effort to regulate core temperature and enhance blood flow to the skin for heat dissipation. This process helps facilitate cooling through mechanisms like evaporation.

Therefore, as temperature rises, it evokes physiological adjustments in both frogs and humans that result in an increased heart rate, making the choice of heart rate increasing the correct one.
