Avery's experiments showed that bacteria are transformed by “transforming principle” – DNA.
When Griffit in his experiments showed that R-strain bacteria (non-virulent) could be transformed by the heat-killed S bacteria, and become virulent, scientists assumed that there is some kind of “transforming principle” that is involved.
Avery and his colleagues cultured heat-killed S cells and tried t separate cellular components that could possibly be that “transforming principle”. Molecule of DNA gave positive result in a chemical test and also when enzymes able to degrade DNA were introduced, the transforming activity was eliminated.
Answer:
The light bulb will have the same mass on the moon as it will on earth. The mass of an object will not change if the gravitational pull on the object changes, but the weight of the object will. For instance, if you measure your mass on Earth and then measure your mass on the moon, your mass will remain the same. The same theory applies to any object with mass.

Answer: DNA was the first genetic material.
Explanation:
The genetic code is essentially the same in all the organism. This states that the similar organism can have similar genes in them that codes for the similar proteins hence, called as similar organism.
The genetic material is chemically made of nucleotide which is either being synthesized in the body or being obtained from the environment similar to that of amino acids.
If the genetic code is same one organism descend from the other organism.But these statement does not supports that DNA was the first genetic material to found in living beings.
Answer:
The correct answer will be Option-A
Explanation:
Photorespiration is the process which takes place in the conditions observed with high atmospheric temperature.
During these conditions, the binding affinity of the RUBISCO enzyme increases for the oxygen which leads to the formation of two compounds mainly which is a three-carbon compound called 3- phosphoglycerate and a two-carbon compound called 2-phosphoglycolate.
The three-carbon compound can enter the Calvin cycle but two carbon compound cannot enter the Calvin cycle and thus is usually lost.
Thus, option-A is the correct answer.
