Amoeba is a ___________ celled organism. It reproduces by ___________ reproduction. The process of reproduction begins by the division of its ___________ into two. This is followed by the division of its___________ into two. This type of reproduction is called ___________ fission.

• A. Cytoplasm, asexual, binary, single, nucleus
• B. Single, asexual, nucleus, cytoplasm, binary
• C. Binary, Single, asexual, nucleus, cytoplasm
• D. Binary, Single, asexual, cytoplasm, nucleus.

Answer 1

The correct option is B Single, asexual, nucleus, cytoplasm, binary

An amoeba is a type of single-celled organism which has the ability to alter its shape by extending and retracting its pseudopodia. So, blank 1 contains the word 'single'.
The mode of reproduction in amoeba is asexual reproduction. So, blank 2 contains the word 'asexual'.
As genetic material or nucleus is first replicated and divided, and then the cell is divided, blank 3 and 4 contains the word 'nucleus' and 'cytoplasm' respectively. While the last blank contains the word 'binary', as amoeba reproduces by binary fission.
Thus, the correct answer is option (B), 'Single, asexual, nucleus, body, binary.'.
