Which scenario is BIOLOGICALLY IMPOSSIBLE based on what you have learned?
AAn Amoeba reproducing by binary fission
BA new Hydra developing from a fertilised egg that fuses inside a test tube without any parent cells
CA frog reproducing by external fertilisation in pond water
DA hen producing an egg through internal fertilisation and then laying it before the chick hatches
Answer & Solution
Correct answer: B. A new Hydra developing from a fertilised egg that fuses inside a test tube without any parent cells
Fertilisation requires both an egg and a sperm — gametes produced by Hydra parents in the first place. An egg cannot just spontaneously appear and fertilise inside a test tube. The other three are all genuine biological processes described in the chapter.
