Biodiversity (Acellular Life/ Variety Of Life) MDCAT Quiz with Answers

Biodiversity (Acellular Life/ Variety Of Life) MDCAT Quiz; Biodiversity is defined as the variety and variability of life on Earth, including species diversity, ecosystem diversity, and genetic diversity within species. It also contains cellular and acellular life, which separates the existence of viruses and prions from other life forms. Cellular life includes bacteria, plants, fungi, and animals, while acellular life represents nonliving substances capable of causing diseases but are otherwise not fully regarded as life forms in the biological sense. Earth has substantial biodiversity, which plays an important role in maintaining stability, cycling resources, and human health. The diversity of microorganisms, like bacteria, to complex multicellular organisms, like human beings, provides stability to nature. Description of biodiversity, knowledge of its parts, such as cellular and acellular life, is a key to answering various questions in ecology, evolutionary biology, and conservation for MDCAT students.
