To answer the questions, I will provide a response based on general knowledge, as the specific article referenced is not available.

Question 1: Which of the following struggles to retain sufficient heat?

• Mice
• Elephants
• Rhinoceroses
• Hippopotamuses

The answer is: Mice.

Explanation:

• Mice: Small animals like mice have a high surface area to volume ratio, which makes it difficult for them to retain heat. They lose heat quickly to the environment and often need to find ways to stay warm.
• Elephants: Elephants are large animals with a low surface area to volume ratio, which helps them retain heat. They are more concerned with dissipating excess heat.
• Rhinoceroses: Similar to elephants, rhinoceroses are large and have adaptations to manage heat, rather than struggling to retain it.
• Hippopotamuses: Hippos also have adaptations for heat management, such as spending time in water to cool down.

Question 2: What is the primary tactic primates use to avoid overheating?

The answer is: Primates often use behavioral adaptations such as seeking shade, resting during the hottest parts of the day, and using their hands to fan themselves or splash water to cool down.

Explanation: Primates, including humans, use a variety of strategies to avoid overheating. These can include:

• Seeking shade: Primates often move to shaded areas to escape direct sunlight.
• Resting during peak heat: Many primates reduce activity during the hottest parts of the day.
• Using water: Some primates may use water to cool off, either by drinking or splashing it on themselves.
• Sweating: Humans, a type of primate, use sweating as a primary means of thermoregulation, though not all primates sweat as effectively.

In summary, mice struggle to retain heat due to their small size, and primates primarily use behavioral adaptations to avoid overheating.
