B is the correct answer
A prokaryote cell has no distinct nucleus with a membrane and neither does it have other specialized organelle.
In a eukaryotic cell, the genetic material is DNA in the form of chromosomes which are found within a distinct nucleus.
Examples of prokaryotes Streptomyces soil bacteria (from which streptomycin antibiotic is derived), Escherichia coli bacterium and Streptococcus bacteria (which causes strep sore throat).
Examples of Eukaryotes include protozoa such as amoeba, fungi, plants, animals and generally all multicellular organisms.

Chromosomes are made up of DNA tightly coiled many times around proteins
The answer is D. NADH to NAD+
When no oxygen is present, anaerobic respiration occurs.It is the only way to produce ATP in this condition.NAD+ is necessary because it is converted into NADH and at the same time ADP is converted to ATP in the reaction of pyruvate synthesis from glucose.Therefore, NADH must be converted to NAD+ in order to have NAD+ always present in the cell.
<h2>Answer </h2>
Photosynthesis
<u>Explanation </u>
If the carbon dioxide is present in the stomata that means the process of photosynthesis takes place because in this process the carbon dioxide is absorbed by the leaves through the small pores called as stomata present on leaves. For the plant's grow the carbon dioxide and water absorption is essential and during the process of photosynthesis, oxygen is released which essential for the human body. For the photosynthesis the energy is required which is taken from the sunlight.
