1. if an animal is an ectotherm, it has (1 point) a skeleton on the outside of its body. a skeleton on the inside of its body. a body that regulates its own internal temperature. a body that does not produce much internal heat. 2.how to mark brainliest if you are correct

1. The correct answer is- A body that does not produce much internal heat.

Ectoherms are those animals whose body temperature depends on their surrounding temperature. They do not produce much internal heat. These animals rather absorb heat from their environment in order to regulate their body temperature. They are called cold-blooded animals.

Example- Reptiles, amphibians, fishes, and invertebrates.

Thus, if an animal is an ectotherm, its body does not produce much internal heat.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
