Why is it important that living organisms not reach equilibrium in the concentrations of oxygen and carbon dioxide?
Mashcka [7]

Answer:

The living organisms must not reach equilibrium in the concentration of oxygen and carbon dioxide so that the Exchange of gases continues . Otherwise respiration and photosynthesis will stop.

Explanation:

  • Gases move along the concentration gradient i.e. from their higher concentration to lower concetration.
  • If living  organisms reach a equilibrium of carbon dioxide and oxygen concentration, then The gases will not move in and out of the cells.
  • This is because at state of equilibrium the concentration of gases on both side become equal and the movement completely ceases.
  • If gaseous exchange in the body stops the process of respiration and photosynthesis in Plants and respiration in animal will completely stop.

Why can sharks swim quickly through water
Eduardwww [97]

The reason why sharks can swim fast is that unlike most fish, sharks have tails that are not horizontally symmetrical . Instead , the top of a shark's tail protrudes further  back than the bottom , giving the shark  lift while swimming and making it "spring" forward at speed.

Most fish make a single water "ring"  that moves backward at the end of their tail's stroke but sharks are thought to produce two rings because of their asymmetrical  tail which bespeaks a more efficient propelling action.

It has also been discovered that sharks can raise the tiny teeth-like structures called placoid scales on their skin to create tiny wells across the surface of their skin  which reduces drag just like the dimples on a golf ball, thus enabling the shark move forward faster.
