Endotherms can insulate (stop heat loss from) their bodies but can only control their body temperature by choice.
The correct statement is:
Endotherms can insulate (stop heat loss from) their bodies but can only control their body temperature by choice.
To determine which statement is true, we need to analyze the options provided:
1. "Ectotherms can insulate (stop heat loss from) their bodies and can control their body temperature by choice."
2. "Endotherms can insulate (stop heat loss from) their bodies but can only control their body temperature by choice."
3. "Ectotherms cannot insulate (stop heat loss from) their bodies and can only control their body temperature by choice."
4. "Endotherms cannot insulate (stop heat loss from) their bodies and can only control their body temperature involuntarily."
Let's break down the terms:
- Ectotherms: These are organisms that rely on external sources of heat to regulate their body temperature, such as by sunbathing or seeking shade.
- Endotherms: These are organisms that can generate and regulate their body heat internally, usually through metabolism.
Now, let's evaluate each statement:
1. "Ectotherms can insulate (stop heat loss from) their bodies and can control their body temperature by choice."
- This statement is not entirely accurate. Ectotherms do not have the ability to insulate their bodies to the same extent as endotherms. They can utilize behaviors like seeking out warmer or cooler environments to regulate their body temperature, but they do not have the ability to insulate themselves as effectively as endotherms.
2. "Endotherms can insulate (stop heat loss from) their bodies but can only control their body temperature by choice."
- This statement is partially true. Endotherms, such as mammals and birds, have the ability to insulate their bodies through various mechanisms, including fur, feathers, or fat. They also have the ability to actively control their body temperature by regulating heat production or by seeking out cooler or warmer environments.
3. "Ectotherms cannot insulate (stop heat loss from) their bodies and can only control their body temperature by choice."
- This statement is more accurate than statement 1. Ectotherms have limited ability to insulate their bodies, and their body temperature largely depends on external factors rather than any active insulation mechanism.
4. "Endotherms cannot insulate (stop heat loss from) their bodies and can only control their body temperature involuntarily."
- This statement is incorrect. Endotherms, as mentioned earlier, have the ability to insulate their bodies using various methods. They can actively control their body temperature through physiological and behavioral adaptations.
Based on the evaluations, the most accurate statement is number 2: "Endotherms can insulate (stop heat loss from) their bodies but can only control their body temperature by choice."
