Emerging viruses
Pathogenic RNA is called a retrovirus.
The theory you are referring to is called allopatric speciation. It suggests that new species can evolve when a population becomes geographically isolated, leading to genetic divergence and eventually the formation of distinct species.
a pathogenic organism is an organism that is harmful to human cell rebuildingany organism which is causing any infection or disease causing alterations our immune system are called pathogenic organisms. the organisms like bacteria virus fungi can be termed as pathogens. the organism can be pathogenic by it self causing sever damage to the immune system or the metabolocal toxins released as byproduct.Path means disease. -gen means to make. It really helps to learn medical terminology. The word then means to make a disease. So a pathogenic organism is one that produces a disease.See link below:Pathogenesis is the creation of disease; when this genesis of disease is caused by [usually] microscopic organisms these microbes are said to be pathogenic.
A non pathogenic organism cause infection in host when the host's immune system is down.It is called as opportunistic pathogen.That infection is known as opportunistic infection.Example for opportunistic pathogen:Candida albicans, Mycobacterium avium-intracellulare, cytomegalovirus (CMV) ---- Pathogen to HIV positive persons.
A pathogenic bacterium is one that has the ability to cause disease in its host. This can be due to the production of toxins or the ability to invade host tissues. Not all bacteria are pathogenic; some are beneficial or harmless.
Pathogenic viruses cause illnesses and disease.
This concept is called allopactric speciation.
Pathogenic RNA is called a retrovirus.
Disease-causing agents like viruses, bacteria, and worms are called pathogens. They can invade the body and cause illnesses by disrupting normal bodily functions and triggering immune responses.
A virus that infects and causes harm to its host is called a pathogenic virus. These viruses can lead to various diseases by disrupting normal cellular functions, triggering immune responses, or causing cell death. Examples include the influenza virus, HIV, and the Ebola virus. Pathogenic viruses can vary in severity, with some causing mild symptoms while others can be life-threatening.
Pathogenic bacteria.
Attenuated simply means "weakened". An attenuated flu vaccine refers to vaccines made with live viruses (so you get a good immune response), but they have been weakened chemically so that they are unable to give you the flu. There are two types of flu vaccines available in the US. What is called inactivated, inactive or "dead" vaccine and what is called "live", weakened/attenuated vaccine. The injectable vaccines (intradermal and intramuscular) are made with "dead" viruses and the nasal spray is made with "live" attenuated viruses.
Population
The theory you are referring to is called allopatric speciation. It suggests that new species can evolve when a population becomes geographically isolated, leading to genetic divergence and eventually the formation of distinct species.
These are called intracellular parasites. All viruses are in this group. Obligate bacteria types include Rickettisae and Chlamydia. Also there are a few that are considered to be non-obligate:Mycobacterium and Brucella.
It called a tor. I too was doing the newspaper crossword!
Its called Isolated Incident Its called Isolated Incident
