Answer: Endoplasmic reticulum
Explanation: The endoplasmic reticulum (ER) is responsible for lipid synthesis and detoxification of drugs in liver cells.Report for correction
11. What is the monomer of nucleic acids?
Answer: Nucleotide
Explanation: Nucleotides are the monomers of nucleic acids, consisting of a phosphate group, a sugar, and a nitrogenous base.Report for correction
12. Which molecule is responsible for carrying oxygen in red blood cells?
Answer: Hemoglobin
Explanation: Hemoglobin is the molecule responsible for carrying oxygen in red blood cells.Report for correction
13. What is the primary function of RNA in cells?
Answer: Protein synthesis
Explanation: RNA is primarily involved in protein synthesis, as it carries genetic information from DNA to the ribosomes.Report for correction
