I don't see any of the "following". If you are trying to cut and paste you can't do that on this site.
Yeah, you have to actually write everything down, but do you still need help?
To determine which of the following options is an ectothermic vertebrate, we need to understand the meaning of ectothermy and then classify each option accordingly.
Ectothermy refers to the inability of an organism to regulate its internal body temperature. Instead, ectotherms rely on external sources of heat to raise their body temperature. In contrast, endothermic organisms can generate and regulate their own body heat.
Now, let's examine the options you mentioned and classify them:
1. Human: Humans are endothermic vertebrates as we can generate and regulate our own body heat. So, we can eliminate this option.
2. Snakes: Snakes are ectothermic vertebrates. They rely on external sources of heat, such as the sun, to warm their bodies and maintain their temperature. Snakes are a good example of ectotherms.
3. Birds: Birds are endothermic vertebrates. They have the ability to generate and regulate their own body temperature, which is necessary for their high metabolic rate and flight. So, we can eliminate this option.
4. Frogs: Frogs are ectothermic vertebrates. They adjust their body temperatures by moving to different environments and rely on external sources of heat to maintain their body temperature.
Based on the classification, both snakes and frogs are ectothermic vertebrates.
