The correct Answer is:
To fill in the blanks A, B, C, and D in the statement about viruses, we can break down the information step by step: 1. **Understanding what viruses are**: Viruses are considered acellular entities, meaning they are not made up of cells. They can be described as nucleoproteins because they consist of nucleic acids (DNA or RNA) and proteins. - **Fill in A**: The correct term for A is **nucleoprotein**. 2. **Identifying the protective structure**: Viruses are protected by a protein coat. This coat is specifically known as the capsid. - **Fill in B**: The correct term for B is **capsid**. 3. **Understanding the composition of the capsid**: The capsid is made up of smaller units known as capsomers. These are the building blocks that assemble to form the capsid. - **Fill in C**: The correct term for C is **capsomers**. 4. **Identifying what is protected by the capsid**: The capsid protects the internal genetic material of the virus, which can be either DNA or RNA. - **Fill in D**: The correct term for D is **genetic material**. Putting it all together, we have: - A: nucleoprotein - B: capsid - C: capsomers - D: genetic material ### Final Answers: - A: nucleoprotein - B: capsid - C: capsomers - D: genetic material
