Answers :-
1) Paramecium shows transverse binary fission
• Transverse binary fission is defined as the spiltting of a unicellular organisms into two identical daughters cells
• Examples of transverse binary fission are Amoeba, paramecium etc.
Option A is your answer mate
2) In meiosis, the number of chromosomes becomes half
• Meiosis is defined as the division of cell into four daughter nuclei.
• In most of the cases, Formation of gametes involves meiosis so that the number of chromosomes becomes half in gametes.
• Example :- If an organism is diploid then the somatic cells of an organisms have 2n number of chromosomes, the meiosis in gamete formation results in the production of haploid gametes.

3) Generally, Every month one ovum is released in the abdominal cavity
•Ovum is a female reproductive cell and after fertilization it will results into embryo.

• Unisexual flowers are those flowers which contain only one sex that is male or female
• Examples are :- Papaya, mulberry etc.
Option D is your answer mate
5) Nutrients is a chemical factor of abiotic components
• Chemicals factors are those factors which results into growth and development of an organisms
