Gas diffusion is dependent upon the partial pressure of gasses.

Biology

Kitty [74]4 years ago

Diffusion is helping these gases to do the gas exchange at alveoli, and blood capillaries. And diffusion depends on partial pressure because it is the pressure produced by the gas in a mixture when it occupied by its own volume.

Explanation:

  • In a body, the gas exchange will occur in two places, one is lungs where oxygen will take and carbon dioxide will release into the respiratory membrane. The second place the tissues where the oxygen is released and the carbon dioxide is taking.
  • In external respiration, exchanging gases with the external environment and this occurs in the alveoli of the lungs. In the internal respiration, change of gases will happen with the internal environment and occurs in the tissues.
  • The exchange of gases is happened because of the simple diffusion. Diffusion is the process at which the gas-particle will move from high concentration to low concentration.
  • there is no energy required to move carbon dioxide or oxygen between the membranes. Because they will create a pressure gradient which allows them to diffuse between the membranes.

goblinko [34]

Answer:

A. Toxic algae blooms that remove oxygen from the water.

Explanation:

According to my recent research, I got to know that "An abundance of healthy nutrients" can be the answer, but here it mentions "HEALTHY" but the nutrients that are coming from the fertilizers, are only good for plants, not for other things that live in the water (fish). So, that's why, An abundance of healthy nutrients is NOT the answer.

A huge overpopulation of oysters is also NOT the answer either.

And, Plastic to wash up on the shore of the bay, can be one answer, but isn't.

So, your answer is A. Toxic algae blooms that remove oxygen from the water.
