mixas84 [53]2 years ago

Based on the nature of proton gradient, (A) is false, but (R) is true.

<h3>What is a proton gradient?</h3>

A proton gradient is a gradient that exists due to difference in proton concentration between the inner and outer mitochondrial matrix.

An assertion is a statement or claim stating a given position.

  • Assertion (A): A proton gradient cannot be established in the mitochondria.
  • Reason (R): Hydrogen molecules are pumped out of an internal space (the matrix) in the mitochondria.

The assertion, A, is false because a proton gradient is established in the mitochondria due to the function of the proton pump which pumps out protons from the inner mitochondrial matrix to the outer membrane.

The reason, R is true as hydrogen molecules are pumped out of an internal space (the matrix) in the mitochondria by the proton pump.

Therefore, (A) is false, but (R) is true.

omeli [17]

Answer:

What will happen to the population of mice that it will keep growing at a tremendous rate without a fear of being caught by a predatory. This will increase the population curve of mice but will decrease the population curve of the cat at similar speed.

What else can happen is that cats will no longer be depending on Mice for their food and they will be finding some alternate food host.

What else can happen is the trait of tailless cannot  be favored by environment as proposed by Lamarack in his theory of evolution that if organism acquires some favorable trait during his life then it is possible that he will pass this trait to offspring. Though this trait is not naturally induced therefore,  there are no chances that tailless mice can born and nature choose it as a favorable trait.

In 1880 August weismenn did experiment of similar nature, he cut off the tails of 20 successive generations of mice abut not a single tailless mouse was born. Therefore, he proved that until nature selects some traits, they are not that easily passed from one generation to another if induced by human.

Conclusion: <em>Therefore, after 50 generation mice will be just like parent mice with tails however they will have good population and less predators.</em>

The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.
