"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.
Operons afford the organism the opportunity to
simultaneously regulate transcription of multiple genes, whose products are
active in the same process. Operons lead to the synthesis of groups of functionally
related enzymes, usually from a single mRNA transcript hence makes regulation of
the genes highly efficient.
