About the tail of the T4 phage, which one is not true:
Correct answer: C. The core and sheath are made of the same type of protein
- A. The core, or tube, is made up of distinct proteins
- B. The core or tube is enclosed in a sheath
- C. The core and sheath are made of the same type of protein
- D. The Core and Sheath are made of another type of protein
Explanation
The answer is "Core and sheath are made of the same type of protein."Explanation: The core of the tail is made up of a rigid and inflexible protein, whereas the sheath is made up of a flexible and contractile protein. The core is the genetic material of the phage, which is made up of DNA. The sheath is a protein coat that surrounds the core and protects it from the environment. The sheath also helps the phage to attach to the host cell.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
