Answer:
Because older cultures of gram-positive bacteria tend to lose their ability to retain crystal-violet in the peptidoglycan of their cell walls and can be confused with gram-negative bacteria.
Explanation:
Gram staining is used to differentiate between two major groups of bacteria. Gram-positive and gram-negative, these bacteria differ in the amount of peptidoglycan in their cell walls. Gram-positive bacteria have a higher amount of peptidoglycan, which absorbs the violet crystal complex used in gram staining, staining them purple/violet. Old cultures of gram-positive bacteria tend to lose the ability to retain the violet crystal and are stained by safranine, staining them red/pink and appear to be gram-negative.
ATP helps in muscle contraction, active transport, formation of lysosomes, etc., while DNA carries all the genetic information related to an organism.
<h3>What do you mean by DNA molecule?</h3>
The DNA molecule may be defined as the molecule that carries the genetic information for the development and functioning of an organism.
ATP delivers energy for chemical reactions in the cell. DNA maintains and communicates the genetic information of organisms.
Therefore, the above statement that best compares the function of an ATP molecule to a DNA molecule.

The electromagnetic radiation with the shortest frequency is MICROWAVES.
Electromagnetic spectrum refers to the distribution of electromagnetic radiations according to their frequency or wavelengths. Electromagnetic spectrum is made up of many type of radiation, which have different properties. The frequency of electromagnetic radiation refers to the number of wave cycle that is formed per second. The electromagnetic radiation with the highest frequency is gamma ray while the radiation with the shortest frequency is radio wave. For the question given above, the radiation with the shortest frequency is microwaves.
