Answer 1

The statement that accurately describes a similarity between the circulatory systems of humans and frogs is:

Both humans and frogs have closed circulatory systems with pulmonary and systemic circulation.

Humans have a four-chambered heart and a completely separated pulmonary and systemic circulation, while frogs have a three-chambered heart with some mixing of blood, but they do have a closed circulatory system that includes these types of circulation. Other statements provided are incorrect.
