Bacteria are the microscopic organisms and included in the prokaryotes as they do not have nucleus. Two main types of bacteria are gram positive bacteria and gram negative bacteria.
The gram positive bacteria has thick cell wall peptidoglycan cell layer and can uptake the crystal voilet stain. These bacteria seems purple under the microscope due to the uptake of stain. The bacteria Streptococcus pyogenes are spherical in shape and occurs in the cluster of chain.
Thus, the correct answer is option (d).
Answer:
Option (2).
Explanation:
Ames test is used to identify the mutageneicity of the compound. The bacteria are treated with chemicals in the nutritive environment to determine whether the substance can acts as a mutagen or not.
The bacteria that can restore the biosyntheic activity in the environment can be considered as mutagen. The mutant bacteria can be easily identified in the Ames test.
Thus, the correct answer is option (2).
