The individual bacteria would appear larger under the magnification of 40X. Thus, the correct option is A.

<h3>What is Magnification?</h3>

Magnification may be defined as the power of a microscope to deliver an image of an entity at a scale larger and sometimes smaller than its genuine size.

Bacillus subtilis is a distinct germ, that is rod-shaped in structure and is Gram-positive. Under the 40X microscope, it looks as rough, opaque, fuzzy white, or narrowly yellow with irregular edges.

The size of the entity or any object under the microscope of 40X magnification is 5mm, while the of the entity or any object under the microscope of 10X magnification is 1-2mm.

Therefore, it is well described above.

12345 [234]

Answer:

a. transcription/RNA processing : pre-mRNA, snRNA

b. translation : mRNA, rRNA,

c. not used in protein synthesis: RNA primers

Explanation:

pre-mRNA, mRNA, rRNA, RNA primers, snRNA

a. transcription/RNA processing : pre-mRNA, snRNA

b. translation : mRNA, rRNA,

c. not used in protein synthesis: RNA primers

The pre mRNA the product after transcription from the DNA is processed eg by addition of poly A tail, splicing etc before undergoing the process of translation, the snRNA also help in performing this function. In translation, the mRNA is trnslated to proteiin in the ribosomes which is also made up of rRNA and proteins. RNA primers is not needed in any of these two, only i DNA replication as the DNA polymerase is uable to begin the synthesis of adding nucleotides to a DNA strand.
