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.
I think the answer for this Question is DNA
The most concentrated source of stored energy is a molecule of "GLUCOSE"
Answer:
The given blank can be filed with stasis.
Explanation:
There are various kinds of species that have been discovered in the world and had remained unmodified, that is, right from the start. This has been supported by their fossil records that in the geological strata they were witnessed unchanged. This phenomenon is termed as stasis, in which the species do not exhibit any kind of directional change. The starfish, lungfish, and the tribolates belong to this category, that is, their current time appearance is identical to the fossil records.
Answer:
plant cell
Explanation:
They are found in bacteria, archaea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls.
