Sharks obtain all of their energy by eating other marine organisms, such as fish. Suppose that a marine scientist measures the c

hemical energy found in a system consisting of a fish and a shark. After the shark consumes the fish, the marine scientist finds that the total energy in the system decreases. If true, would this result validate or invalidate the Law of Conservation of Energy? Why or why not?
Invalidate, because energy should not leave a closed system

Invalidate, because the amount of energy should stay constant

Validate, because this scenario describes an open system

Validate, because the overall energy in the ocean is still unchanged

blagie [28]

Answer:

One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.

One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.

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.
