At first glance, it might seem counterintuitive with respect to energy use that many sharks must swim continuously or they will die. why is it important to their metabolic needs that sharks keep swimming? check all that apply.

Explanation:

This is because they have gills which function through the concurrent exchange of oxygen between the water and the blood of the sharks. This water passes over the gills in the opposite directional flow of the sharks blood in the gills. So the carbon dioxide concentration in the water outside their gills increases due to increase cellular respiration in their muscles.

Therefore, it is important that sharks must swim constantly in order to keep oxygen-rich water flowing over their gills.

The answer to the question above is explained below:

Explanation:

Gill involve external extensions from the body surface, it is the respiratory organ in many aquatic animals. They have feathery parts which cause water to move across the animal's body.

Gills are characterized by large amounts of surface area that function in gas exchange.

Sharks are  type of fish that have no bones, only cartilage.

Why Sharks needs to keep swimming:

Carbon dioxide concentration in the water outside their gills increases due to the increased cellular respiration in their muscles.

Sharks have prominent spiracles, or respiratory openings behind the eyes that allow the fish to pull in water while buried under sand. Carbon dioxide waste also passes from the shark's blood and out of its body through the gill tissue.

As water passes over the gill's membranes, tiny blood vessels extract oxygen from the water.

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
