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.
Answer:
B. Viruses
Explanation:
Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
The correct answer is: c. Mitochondria and d. Rough ER
Protein disulfide bonds are the links between the sulfur atoms of two cysteine amino acids of the protein and these bonds are part of the secondary and tertiary structure of proteins. Formation of disulfide bonds is very important for the folding and stability of some proteins. Disulfide bonds are mostly found in secretory proteins and lysosomal proteins because of their unstable state in cytosol.
The right answer is Wavelengths of energy.
White light is made up of all colors. The rainbow is actually the decomposition of white light by droplets of water like a prism.
Each color corresponds to an electromagnetic radiation of particular frequency and wavelength.
The sensitivity of the eye is maximum around 550 nm, in the yellow-green. The spectrum of visible light ranges from 400 to 780 nm but its perception depends on each individual (tastes and colors ...).
Explosive mechanism is a method of self dispersal of seeds by the plants. Some plants distribute their seeds by violently ejecting them so that they fall well away from the parent plant.
