For Question 12, the correct response would depend on the specific information provided in Slides 14-15. Generally speaking, humans have more spinal nerves than frogs, primarily because humans possess more complex structures and functions. Thus, the response would typically be "Humans have more spinal nerves than frogs."
For Question 13, the cerebrum in both humans and frogs primarily plays a role in processing sensory inputs and allowing for conscious thinking. Thus, the response that best fits this role would be "Allows for conscious thinking and responses to feelings of hunger, fear, and thirst."
If you have specific information from Slides 14-15 that might alter these responses, please let me know!
