Answer:
The rainforest jaguar, exhibits a well-known mammal characteristic, as it waits for its opportunity to pounce on its prey. Mammals are known to be dominant in its environment, actively seeking its targets. Furthermore, the hairs on the jaguar would be an indicator of its status as a mammal. As mammals are known to have hair, and it is thus a mammal characteristic. They are known to be warm blooded, and one instance in the passage that hints at the jaguar's warm bloodedness would be when it pants in order to stay cool.
Note:
this is really vague lol, since I don't know your teacher's lesson plan, so I'm not sure what mammal characteristics are pointing towards (biological, or behavioral?) so note that this response might not be what your teacher is looking for.
