Final answer:
Protective measures for cell survival during torpor include maintaining lower temperature, regulating pH levels, and employing chemical adaptations.
Step-by-step explanation:
Cells require protective measures to stay alive during periods of torpor. One important measure is maintaining proper temperature. Torpor is a state of decreased activity and metabolism, so cells need to maintain a lower temperature to conserve energy. For example, hibernating ground squirrels can achieve an abdominal temperature of 0°C to reduce metabolic activity. Another protective measure is maintaining pH levels. Cells need to regulate their pH to ensure proper function. Additionally, cells may employ chemical adaptations, such as the wood frog having an antifreeze-like chemical in its cells to prevent them from freezing and bursting during torpor.
