Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water.
</u>
Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.
Since, oxygen is consumed during respiration, option 1 is incorrect.
Loss of electrons is reduction, so option 2 is also incorrect.
Glucose is used in respiration, thus option 3 is incorrect.
If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.
<h3>What is the activity of methylated DNA?</h3>
DNA methylation is a process by which methyl is added to the DNA molecule which can change the activity of a DNA without changing the sequence. When it is located in a gene promoter, DNA methylation acts to repress gene transcription.
So we can conclude that If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.
