Answer:
D
Explanation:
because cell are not pre existing
Answer: Nucleiod, Ribosomes, flagella, fimbriae, plasma membrane
Explanation: A typical bacteria cell possess these structures mentioned above. nucleiod is a chromosome , a nucleic acid which can be DNA or RNA, It is the genetic material of cell which every bacteria cell must have. Flagella ensures swimming movement of all bacterial cell. Ribosome of bacteria cells ensures protein synthesis. Since all bacteria cells meet, plasma membrane is permeability barrier, location of enzyme and transports solutes. Fimbriae enables bacterial cells attachment to surfaces
It is <u>TRUE</u> that multiple polypeptides joined together represents the tertiary level of protein organization.
