What is the smallest group of living things?
The smallest living things depend on how a living thing is defined. Some biologists do not believe viruses are living organisms because there are no free living forms (all are parasitic) and because they must reply on their host for reproduction. Others believe that, despite this, they have an existence of their own separate to the host and are subject to natural selection and are therefore alive. If you accept viruses are not alive, the smallest living things would be amongst the bacteria or protists. Bacteria are single celled organisms with no cell nucleus while protists have a nucleus. Generally the bacteria are slightly smaller but their sizes overlap. If you accept that viruses are alive, the smallest group are the Parvoviruses between 18 and 26 nanometres. These are single stranded DNA viruses. 1 nm = 1/1000000000 metres or 0.000039 inches.
What 5 groups are microorgainisms classified with?
Microorganisms can be classified into 5 groups which are very similar to the kingdoms of life. The groups are: viruses, bacteria, algae, fungi, and protozoa.
One of a group of disease causing substances dependent on living tissue for reproduction and growth?
Viruses are a group of disease-causing agents that require living cells to replicate and grow. They invade host cells and use their machinery to produce more virus particles, often leading to various illnesses.
What are the kingdoms of corona viruses and rhino viruses?
Coronaviruses and rhinoviruses belong to different families within the realm of viruses. Coronaviruses are classified under the family Coronaviridae and are known for their crown-like appearance due to spike proteins on their surface. Rhinoviruses, on the other hand, belong to the family Picornaviridae and are primarily responsible for the common cold. Both types of viruses are RNA viruses, but they differ significantly in their structure, transmission, and the diseases they cause.
Are bacterial viruses with a polyhedral head attached to a helical tail?
No, bacterial viruses with a polyhedral head typically have a tail associated with the head structure. These viruses are known as bacteriophages. The tail plays a critical role in attaching to the host bacteria and injecting the viral genetic material into the bacterial cell for replication.
What are the viruses called?
They all have their own names, but as a group they are just viruses.
Is hand foot and mouth disease a bacteria?
Hand, foot and mouth disease is caused by a group of viruses, that belong to genus entero virus. This group include polio viruses, coxsackie viruses, echo viruses and entero viruses.
What type of pathogen is the hand foor and mouth disease?
This disease is caused by the group of viruses, which belong to the genus enterovirus. Mainly coxackie viruses, echo viruses and entero viruses.
What is paramyxovirus?
a group of viruses including those causing mumps and measles
What is cytomegalovirus?
Cytomegalovirus (CMV) is a virus related to the group of herpes viruses.
What is an Enterovirus?
it is any of a group of viruses that primarily affect the gastrointestinal tract
What is enterovirus?
it is any of a group of viruses that primarily affect the gastrointestinal tract
What is the group of viruses that infect the liver?
Viruses that cause liver disease are placed under the term 'hepatitis'. Other things can cause hepatitis besides viruses, heavy alcohol use can as well.
Are interferon's viruses?
Interferons are not viruses. They are a group of signaling proteins released by cells in response to the presence of pathogens like viruses. Interferons help to regulate the immune response and inhibit viral replication within infected cells.
What characteristics do scientists use to group viruses?
Viruses can be grouped by their shape, the type of disease they cause, their life cycle, or the kind of genetic material they contain. And, the four main shapes of viruses are: Crystals, Spheres, Cylinders, and Spacecraft.
Under what group of organisms will fungi fall?
Fungi will fall under a group of organisms that are known as microbes. The other organisms in this group include archea, bacteria, protists and viruses.
Is there one or several flesh eating viruses?
Surprisingly yeas there is a few *flesh eating viruses/bacteria*
