Amino acids are acids on one hand, and a base on the other hand.

<h3>What is an acid?</h3>

An acid is a substance that produces hydrogen or hydroxonium ions as the only positively charged ion when it ionizes.

All amino acids have an amine group -NH_2 and a carboxylic group -COOH.

The carboxylic group ionizes such that:

COOH -- > COO^- + H^+

The presence of the amine group enables amino acids to also act as a base.

Saltwater fish constantly drink water but still excrete concentrated urine to compensate for the water loss. They also have gill
Dmitrij [34]

Answer:

The above paragraphs describes that how salt- and fresh-water fish regulates their osmoregulation. Hence, the correct answer would be c. have adapted to deal with osmosis.

Osmosis is the process by which solvent's molecule move from region of low concentration (hypo-tonic) to the region of high concentration (hyper-tonic) through a semi-permeable membrane.

In sea-water fishes, the body fluids are hypo-tonic to the surrounding water and thus water is kept moving out of their gills. In order to prevent the excess water loss they need to drink water constantly and excrete concentrated urine.

In contrast, fresh-water fishes body fluids are hyper-tonic to surrounding water and hence, water keeps entering in their body through gills. So, in order to prevent excess dilution they absorb salt from surrounding with the help of gills and also their bodies reabsorb salt from urine.
