On land, frogs are:
Correct answer: D. None of these
- A. Hypermetric
- B. Cerebral cortex
- C. Normal sighted
- D. None of these
Explanation
Options A and B are terms related to the Central Nervous System. Option C is incorrect because frogs are naturally near-sighted. D is correct because on land, frogs are myopic. This is correct as the eyes of frogs are myopic on land, which means that their eyes are nearsighted, and the large, round lens of the frog gives the animal a large field of view. They are naturally nearsighted, which means myopic to -6 diopters, which gives the focus of approximately 6 inches.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
