Question

Frogs have lungs for breathing, but they also absorb dissolved oxygen directly through their skin. This allows respiration to occur when they are underwater. When they are on land, mucus keeps their skin moist to continue to absorb dissolved oxygen from the air. Which statement about water is best illustrated by this example?
A) Liquid water can transport nutrients
B) Water breaks down into oxygen molecules for respiration
C) Water is found in every cell of an animal’s body
D) Liquid water is necessary for plants and animals

Answer 1

Answer;

B) Water breaks down into oxygen molecules for respiration

Explanation;

-While completely submerged all of the frog's respiration takes place through the skin. The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels.

-The thin membranous skin is allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.

Answer 2

"Water breaks down into oxygen molecules for respiration" is the one statement about water among the choices given in the question that is best illustrated by this example. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer has helped you.
