Answer:
Isolated chloroplasts or mitochondria cannot be considered alive, because although they can survive while isolated for a few hours or days and they resemble that of an independent cell (which are alive), they don't metabolise energy, and they don't have cells.
The answer would be D without reproduction there would be no offspring to carry on. It may not always include 2 organisms, some may be asexual, meaning they produce by themselves.
The correct answer is: C) A large number of phages are released at a time
Lytic cycle of a bacteriophage is one of the two life cycles of viruses, other being lysogenic. Lytic cycle can be divided in stages:
• Attachment-viruses binds to the receptor on the surface of bacterial cell, usually it uses tail for the attachment
• Entrance-virus injects its genome material (DNA or RNA) into bacteria cell
• Replication and protein synthesis-virus uses mechanism of bacteria to replicate its genome and produce proteins. As a consequence, a huge number of new viruses are formed
• Lysis- viruses express protein for the bacterial lysis (bacterial cell expand and burst) and hundreds of new phages are released.
