The question is incomplete as it does not have the options which are:
A. novelty
B. creativity
C. consensus
Answer:
A. novelty
Explanation:
Novelty refers to a qualitative identity that is used to represent the new ideal things or some fresh and refreshing ideas.
In the given question, the person who was presenting about the idea of How DNA works in genetics? failed to present something new about the DNA and just presented what was already known to the audience.
Since the presenter failed to express the new ideas in his presentation about the DNA that is no novel ideas were presented therefore the audience started to leave the presentation.
Thus, Option-A is correct.
Answer:
Well to give a good example of "ecosystem increases its biodiversity" we must first define
biodiversity

SO an example would be like bringing a frog from china to a pond in amercia,but this frog is new and there arent any frogs from the speicus
C, doubling the mass, as the bigger the object, the more energy is stored. Would appreciate brainliest!
The ratio of 
indicates the purity of nucleic acid.For pure DNA it should lie between 1.8-2.0.Whereas for RNA it should be greater than 2.
This is calculated for DNA using the given values of absorbance-
= 2.71
As the value is greater than 2.0,it reflects the RNA contamination in the sample.
