Pili are the filaments that help some bacteria stick to surfaces and exchange plasmids through conjugation.
Pili are hollow, hair like appendages that are found on the surface of some bacterial cells. Pili are composed of a special protein (known as pilin). Pilia act as a means of attachment of bacteria to surfaces (such as their host) and it is also used by bacteria to exchange their genetic material (plasmids) in the mating process between cells (known as conjugation).

Substitution Mutation - A mutation that exchanges one base for another. For this example substitute A with G which will result in this sequence:
GCTGGTCGGCTG
Deletion Mutation - A mutation in which a section of the DNA is cut or lost.
GCTAATCGGCTA -> GCTCGGTA; section AAT was deleted
Insertion Mutation - Extra base pairs are inserted into a new place within the DNA
GCTAATGCGCGGCTA - GCG was added after AAT

The characteristic of a urodeles is a Salamander
Answer: 1.B). Evolution genetics.
2.C). Less Bacteria becoming resistant to the specific Antibiotics .
Explanation:
Evolution genetics is field of science, which includes study of genetic variations that lead to evolutionary changes in organisms. As some bacteria had changed their DNA that led to development of antibiotic resistance in them.
Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them
Thus, the correct options to be filled in the blanks are option (B) and option (C).
