No one knows exactly when viruses emerged or from where they came, since viruses do not leave historical footprints such as fossils. Modern viruses are thought to be a mosaic of bits and pieces of nucleic acids picked up from various sources along their respective evolutionary paths. Viruses are acellular, parasitic entities that are not classified within any domain because they are not considered alive. They have no plasma membrane, internal organelles, or metabolic processes, and they do not divide. Instead, they infect a host cell and use the host’s replication processes to produce progeny virus particles. Viruses infect all forms of organisms including bacteria, archaea, fungi, plants, and animals. Living things grow, metabolize, and reproduce. Viruses replicate, but to do so, they are entirely dependent on their host cells. They do not metabolize or grow, but are assembled in their mature form.
Viruses are diverse. They vary in their structure, their replication methods, and in their target hosts or even host cells. While most biological diversity can be understood through evolutionary history, such as how species have adapted to conditions and environments, much about virus origins and evolution remains unknown.
Answer:
D. alcohol
Explanation:
Fermentation by microorganisms converts organic materials into alcohol
The correct answer would be option D. The statement that best describes what plasma is in chemistry is, an electrically charged gas with very high kinetic energy. A plasma is defined as a hot ionized gas, which exists at super high temperatures.
Competition is one of the many types relationships in the ecosystem. It is an oppositional relationship because unlike in symbiotic relationships, the organisms do not peacefully coexist. Using the given information above, we can deduce that the two fungi compete with one another in terms of the resources plus the habitat.
Answer:
protists are eukaryotes as they possess a nuclear and other membrane-bound organelles(structures that perform a specific job).
Explanation:
