Most fish exchange gases using gills<span> on either side of the </span>pharynx<span> (throat). Gills are tissues which consist of threadlike protein structures called </span>filaments. These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia.<span>Each filament contains a </span>capillary<span> network that provides a large </span>surface area<span> for exchanging </span>oxygen<span> and </span>carbon dioxide<span>. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causing </span>countercurrent exchange<span>. The gills push the oxygen-poor water out through openings in the sides of the pharynx. Some fish, like </span>sharks<span> and </span>lampreys<span>, possess multiple gill openings.</span>
<span>The
absorption of iron is reduced when you have a diet high in fiber and
phytates. Even though an excess of fiber can have an effect in the
body’s ability to absorb some minerals, fiber is very safe and even
necessary in reasonable amounts. phytatic acids on the other hand are
responsible of binding metallic cations reducing the capacity of the
body of absorbing iron, calcium and zinc and should be consumed with
moderation.</span>
The answer is A, earthquake. Typically, tsunamis can form after an earthquake. This happened in Indonesia a couple of times. I hope this helped! :-)
