Answer:

<em>The above statement is false.</em>

Explanation:

<em>When a single nucleotide is changed at a particular position of the nucleotide sequence, then this change will result in the formation of a faulty protein. </em>

<em>This is because that particular position of the genetic sequence is associated with the formation of a particular protein. All the other proteins formed will be normal. </em>

<em>Hence, we cannot attribute all existing changes between the cichlid and coelacanth/frog on this single nucleotide change.</em>

However, if instead of replacement of a T with a C, an addition or deletion had been made, then the entire genetic code would have been altered. This would have resulted in more number of faulty proteins being formed.

Suppose you discovered a mutant yeast whose glycolytic pathway was shorter because of the presence of a new enzyme catalyzing th
Ganezh [65]

Answer:

The correct answer is  the formation of pyruvate from glucose willl be energetically less favorable.

Explanation:

According to the question matunt yeast has a shorter glycolytic pathay catalysing a follwing reaction

 Glyceraldehyde-3-phosphate+H2O+NAD+  = 3-phosphoglycerate

So in the mutatant the formation of 1,3- bisphosphoglycerate is not occurring.The glyceraldehyde-3-phosphate is directly converted into 3-phosphoglycerate.

    As a result the substrate level phosphorylation step that deals with formation of 3-phosphoglycerate from 1,3  bisphosphoglycerate is not occurring.

  From this point of view it can be said that less energy will be formed in the mutant during glycolysis than that of normal one.

 So the formation of pyruvate from glucose will be energetically less favorable.

Answer:

What is the main advantage to using satellites to measure climate change?

Explanation:

answer A...Satellites in a low earth orbit can directly monitor the climate from their position within or just above the atmosphere, and can provide near-global coverage as they scan over different swathes of ground with each orbit.
