Viruses are not considered "alive" because they lack many of the properties that scientists associate with living organisms. Primarily, they lack the ability to reproduce without the aid of a host cell, and don't use the typical cell- division approach to replication.They don't contain cell ...
To help everyone learn more effectively, I will encourage you to discover the answer to this question by self-learning first.How about you first search for the answer of whether viruses are living things or not from the internet this weekend, and then we can discuss the answer on Monday. A...
Virus definition: an ultramicroscopic (20 to 300 nanometers in diameter), metabolically inert, infectious agent that replicates only within the cells of living hosts, mainly bacteria, plants, and animals. See examples of VIRUS used in a sentence.

Patients infected with HIV are at high risk of developing Epstein-Barr Virus (EBV)-related diseases. The genotype and viral biological behavior of EBV infection in patients with human immunodeficiency virus-1 (HIV) in China remain unclear. This study analyzed the characteristics of EBV in patients...
Viruses are the smallest microorganisms in nature. As such, they areobligateparasites, which means that they cannot live or reproduce without a host. Consequently, viruses are found wherever there are living organisms, including humans. The common cold, chicken pox, cold sores, AIDS, and SARS ar...
Despite decades of research into bats and the pathogens they carry, the fields of bat virus ecology and molecular biology are still nascent, with many questions largely unexplored, thus hindering our ability to anticipate and prepare for the next viral outbreak. In this Review, we discuss the ...
In nature furoviruses are transmitted by the zoospores of Polymyxa graminis which carry the viruses internally, possibly not in form of their virions but rather of RNA-movement protein complexes. There are no indications that furoviruses multiply in their vector. In the long-living resting spores...
Here we examined a similar strategy in which counties with more diverse commuters, quantified by the Shannon diversity: H = − ∑hi ln hi, where hi is the fraction of incoming commuters living in county i, are preferentially selected. To provide an alternate strategy that avoids ...
