Is a submicroscopic particle that infects and resides in the cells of a biological organism?
Viruses: A virus is a submicroscopic particle that infects and resides in the cells of a biological organism.
What term refers to a parasitic particle that infects and resides in the cell of biological organisms?
A virus is a microscopic particle that can infect the cells of a biological organism. Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.
What infects and resides in the cells of biological organism?
Viruses are tiny infectious agents that rely on living cells to multiply. They may use an animal, plant, or bacteria host to survive and reproduce. As such, there is some debate as to whether or not viruses should be considered living organisms. A virus that is outside of a host cell is known as a virion.
Is a virus a submicroscopic particle?
A virus is a submicroscopic infectious particle composed of a protein coat and a nucleic acid core, as shown in Figures 1 and 2. Viruses are similar in size to a large protein macromolecule, generally smaller than 200 nm in diameter.
What submicroscopic particles are the building blocks of matter?
The submicroscopic particles that constitute the fundamental building blocks of ordinary matter are atoms.
Which bacteria are transmitted in the air in dust or within the substance in which they settle?
Cocci rarely show active motility. They are transmitted in the air, in dust, or within the surface in which they settle. Bacilli and spirilla use hair-like extentions called flagella or cilia for movement.
What are infectious diseases also known as?
Communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
How do bacteria infect cells?
Bacteria are much larger than viruses, and they are too large to be taken up by receptor-mediated endocytosis. Instead, they enter host cells through phagocytosis. Phagocytosis of bacteria is a normal function of macrophages.
What is a virion vs virus?
A virion is an entire virus particle consisting of an outer protein shell called a capsid and an inner core of nucleic acid (either ribonucleic or deoxyribonucleic acid—RNA or DNA). The core confers infectivity, and the capsid provides specificity to the virus.
What are viruses that infect prokaryotes called?
Viruses called bacteriophages are able to infect bacterial cells and use them as hosts to make more viruses. After multiplying, these viruses assemble and occasionally remove a portion of the host cell’s bacterial DNA.
What are the 3 building blocks of matter?
Well, the basic building blocks that make up matter are called atoms. Atoms consist of three particles: negatively charged electrons, positively charged protons and neutrons, which have a neutral charge.
What is the building block of all elements except hydrogen )?
All atoms (except hydrogen and helium with their single electron shells) are most stable when there are exactly eight electrons in their valence shell.
