Answer:
B) stain only the thicker peptidoglycan cell walls
Explanation:
Gram staining is a technique which was developed by the Hans Christian Gram in 1884 to distinguish the bacterial strains. Based on the colour absorbed and retained by the bacteria, the bacteria are distinguished either as gram-positive or gram-negative.
He used a colour stain- crystal violet which is a positive dye and binds to the cell wall made of peptidoglycan. The crystal violet binds to the cell wall with the help of a mordant called iodine. If this dye retains inside and the cell appears purple then the cell is considered gram-positive else negative.
Thus, Option-B is correct.
During telophase II, the fourth step of meiosis II, the chromosomes reach opposite poles, cytokinesis occurs, the two cells produced by meiosis I divide to form four haploid daughter cells, and nuclear envelopes (white in the diagram at right) form.

<span>The voyage of the HMS Beagle is led by the scientitst
Charles Darwin in search for species around the globe and a curious observation that led him to
theorize about evolution. It leaves form Plymouth Harbor, toured around the
Madeira and Canary islands and made a landfall at the Cape of Verde islands. The
expedition was originally planned to end in two years. It got delayed and
turned into five years due to Darwin spending most of his time exploring on
land. the answer is D.</span>
