"Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans" is TRUE.
Answer: Option A
<u>Explanation:
</u>
Frogs also have the excretory system with two kidneys and similar to mammals. Its function is to eliminate the nitrogen product from the blood. Frogs make large volumes of dilute urine to wipe out harmful products from the tubules of the kidneys.
Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.
Water pressure and temperature varies at different depths of the ocean.
