Are viri alive?
Viruses are not considered alive by most biologists because they lack the characteristics that define living organisms, such as cellular structure and the ability to reproduce independently. They can only replicate inside a host cell, hijacking the host's machinery to produce more viruses. Additionally, viruses do not carry out metabolic processes on their own. However, they do exhibit some characteristics of life when they infect a host, leading to ongoing debates about their status as living entities.
What is minimal koch's infection?
Minimal Koch's infection, often referred to in the context of Koch's principles, is a term used to describe the presence of a pathogen in a host without causing significant disease symptoms. It suggests that the organism can be present in the host but may not necessarily lead to a full-blown infection or illness. This concept highlights the importance of host factors and pathogen characteristics in the development of infectious diseases.

What are some characteristics of viruses?
some characteristics of a virus: - needs a host - can contain DNA or RNA - can have an envelope cell - is an acellular organism
What are common characteristics of flatworm and roundworms?
parasites digestive system they live on their host's
What are the characteristics of the lag phase?
Characteristics of the lag phase include acute inflammation and the initial appearance and infiltration of neutrophils. Neutrophils protect the host from microorganisms and infection.
What are the characteristics of f plasmids?
They are used as DNA delivery units in biotechnology. It replicates independently of the host chromosome and carries information required for its own replication. Also carries information that adds extra characteristics to the host cell, those characteristics are usually not vital for the cell.
What is the relationship between a virus and a host?
Virus require a host to carry out the most of the characteristics of living organisms. In almost cases, viruses require a host to reproduce (by hijacking the cells of the host and using its DNA to make copies of itself) and also receive the bulk of their energy from the host.
What are some characteristics of parasitic worm?
A successful parasite can source all its needs from the host animal. A VERY successful parasite provides some benefits to its host so that there is real incentive to have a parasite. This is called symbiosis. Successful parasites should/must: Withstand the unfavorable condition, reproduce within the host, egg/cysts easy to leave outside host, locate new host, enter the host simply, and avoid killing the host.

What has the author Lars Weiershauser written?
Lars Weiershauser has written: 'Fluids associated with an Archean regional hydrothermal system, Abitibi subprovince, Canada; Fluid inclusion characteristics and hot cathode cathodoluminescence characteristics of host minerals'
What is breeding value?
Assigning a value to the potential advantages the characteristics a gene may provide and therefore also the advantage to the offspring if the 'host' were to breed.
What viral characteristics are shared with other organisms?
Viral characteristics shared with other organisms include the presence of genetic material (either DNA or RNA), the ability to evolve through mutation, and the capacity to reproduce and spread within a host organism. Additionally, like other organisms, viruses exhibit some level of specificity in terms of host range and cellular tropism.
Characteristics of livivng and non-living viruses?
viruses are connecting link between living and non-living, as they show only one character of living biengs i.e. reproduction but that too is in inside living host cell otherwise they are consider as nonlivings
What once had all characteristics of life?
Viruses are considered to have some characteristics of life, such as the ability to replicate and evolve, but they do not meet all criteria for being classified as living organisms. They require a host cell to reproduce and lack metabolic processes seen in living cells.
