Are protozoa alive?
Protozoa are one-celled animals found worldwide in most habitats. Most species are free living but all higher animals are infected with one or more species of protozoa. Infections range from asymptomatic to life threatening depending on the species and strain of the parasite and the resistance of the host.

Why is fire not considered alive?
The reason fire is non-living is because it does not have the eight characteristics of life. Also fire is not made of cells. All living organisms is made of cells. Although fire needs oxygen to burn this does not mean it is living.

Viruses of all shapes and sizes consist of a nucleic acid core an outer protein coating or capsid and sometimes an outer envelope.

Subatomic means “smaller than an atom.” Atoms are made up of protons neutrons and electrons.
Is chickenpox a virus?
Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV). The virus spreads easily from people with chickenpox to others who have never had the disease or never been vaccinated. If one person has it up to 90% of the people close to that person who are not immune will also become infected.

Two scientists contributed to the discovery of the first virus Tobacco mosaic virus. Ivanoski reported in 1892 that extracts from infected leaves were still infectious after filtration through a Chamberland filter-candle. Bacteria are retained by such filters a new world was discovered: filterable pathogens.

Is virus A parasite?
viruses. All viruses are obligate parasites that is they lack metabolic machinery of their own to generate energy or to synthesize proteins so they depend on host cells to carry out these vital functions.
Is a protozoa a virus?
Protozoa (pro-toe-ZO-uh) are one-celled organisms like bacteria. But they are bigger than bacteria and contain a nucleus and other cell structures making them more like plant and animal cells. Protozoa love moisture.
Do protozoa eat algae?
What was the first human virus?
Are there any good viruses?
In addition to good bacteria we now know there are beneficial viruses present in the gut skin and even blood. Our understanding of this viral component is largely in its infancy. But it has huge potential in helping us understand viral infections and importantly how to fight the bad ones.
Who made the Ebola virus?
The cAd3 vector has a DNA fragment insert that encodes the Ebola virus glycoprotein which is expressed on the virion surface and is critical for attachment to host cells and catalysis of membrane fusion. It was developed by NIAID in collaboration with Okairos now a division of GlaxoSmithKline.
Can a fire grow?
FUEL which can be a solid a liquid or a gas. Once there is a heat source to cause ignition and a sufficient amount of fuel and oxygen present the fire will continue to burn. … This transfer of heat causes the fire to grow and to spread to other areas.

Note: In 1935 tobacco mosaic virus (TMV) was the first virus to be crystallized by Wendell Stanley as an accomplishment for this was awarded a share of the 1946 Nobel Prize in Chemistry. Also his award was the first-ever bestowed as a virologist.
How many virus families are there?
The viruses that infect humans are currently grouped into 21 families reflecting only a small part of the spectrum of the multitude of different viruses whose host ranges extend from vertebrates to protozoa and from plants and fungi to bacteria.
What is the smaller than a Preons?
Preons are hypothetical particles smaller than leptons and quarks that leptons and quarks are made out of. … The protons and neutrons weren’t indivisible – they have quarks inside.
What is smaller than a neutrinos?
An electron has near-zero mass but it actually weighs 500 000 times more than a neutrino (again whose exact measurement is impossible to make at this point). Physicists use electron volts (eV) to measure the mass of subatomic particles Lincoln said. … One electron volt is equivalent to about 1.6×10^-19 joules.
