Answer:
Viriods are the sub-virals which is the smallest agent of infectious disease. While Virus infects the plants and animals, viriod affects the plants only. Common Cold Virus, Influenza virus etc are some of the example of virus. Potato Spindle tuber Viroid is an example of Viroid. The Genome of virus is DNA and RNA but Viroid is consist of RNA only.

Answer:
Neurilemma
Explanation:
Schwann cells are the neuroglia that produces myelin sheaths. There is a formation of multiple layers of the glial plasma membrane around axons. The cytoplasm and nucleus of Schwann cells from the outermost layer while the inner part has multiple layers of the Schwann cell membrane. The outer nucleated cytoplasmic layer of the Schwann cell that encloses the myelin sheath is called neurolemma. It is found only around axons in the PNS. Its function is to serve in the regeneration of injured axons by the formation of a regeneration tube.
Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
