11) Spherical shaped bacteria are called cocci. Rod shaped bacteria are called as bacilli. Some of the bacteria are spiral shaped like leptospira. Bacteria can also form colonies like staphylococcus and Streptococcus. But not all Prokaryotes form multi-cell chains. Therefore, the answer for this question is option 3 (all form multi-cell chains).
12) Prokaryotes directly exchange DNA molecules by means of sex pilus.
13) The structure that contributes to cell shape, reduces cell membrane injuries, and prevents prokaryotic cells from bursting due to osmotic water uptake is cell wall.
14) Prokaryotes survive in extremely harsh and difficult environment for extended periods by forming endospores.
15) Pathogenic bacteria does not cause influenza. Influenza is cause by virus.
