Correct Answer: Four haploid cells
Explanation:
When a cell undergoes meiosis process, it produces 4 haploid cells as a result.
Correct Answer: Forensic science analysis
Explanation:
Mitochondrial DNA analysis is best suited for Forensic science analysis.
Correct Answer: Ribosomes
Correct Answer: Lysosomes
Explanation:
Lysosome is an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane. They are capable of breaking down all types of biological polymers like proteins, nucleic acids, carbohydrates, and lipids.
Lysosomes are known as the suicide bags of cells because whe any cell gets damaged these organelles burst and the enzymes present in it will digest the damaged cell.
Correct Answer: H2CO3
Correct Answer: Lysosomes
Correct Answer: Deoxyribonucleic Acid
Correct Answer: Brain
Correct Answer: 'O'
Correct Answer: Sunlight
