Question

1. ccc cause and effect: if a single - celled organism is unable to undergo cell division, what will happen to that organism?

Explanation:

Single - celled organisms rely on cell division for reproduction (and also for growth, repair, or maintaining population in some cases). If a single - celled organism cannot undergo cell division, it cannot reproduce. Since it is a single - celled organism, without reproduction, the lineage of that particular type of single - celled organism from this individual will end (the organism itself will also eventually die, and there will be no new cells/organisms to replace it or continue its genetic line).

Answer:

If a single - celled organism is unable to undergo cell division, it will be unable to reproduce. Over time, as the existing cell (the organism) ages or is damaged, there will be no new cells to replace it, and the lineage of this single - celled organism (from this individual) will cease to exist as the organism dies and no offspring are produced.
