Verified step by step guidance

Understand the nature of viruses: Viruses are not considered living organisms because they lack cellular structure and cannot carry out metabolic processes on their own.

Examine the statement 'Viruses contain hereditary information': Viruses do have genetic material, either DNA or RNA, which they use to replicate within a host cell.

Analyze the statement 'Viruses do not have the ability to reproduce without hijacking a host cell': This is true because viruses rely on the host cell's machinery to replicate their genetic material and produce new virus particles.

Consider the statement 'Viruses are composed of cells': This is false because viruses are acellular; they do not have a cellular structure like living organisms.

Evaluate the statement 'Viruses do not need to extract/consume energy from the environment to exist': This is true as viruses do not perform metabolic activities and rely entirely on the host cell for energy and resources.
