What is meant by strain in physics?
Strain is simply the measure of how much an object is stretched or deformed. Strain occurs when force is applied to an object. Strain deals mostly with the change in length of the object.
Why is it called a strain?
Cannabis strain. In botanical terms, strain once meant offspring or descendants from specific plants, though this use has fallen out of favor. It’s a more common and accurate term in microbiology and biology where it means a genetic variant, like the delta strain of the COVID-19 coronavirus.
What is strain in microbiology?
Microbiology and virology A strain is a genetic variant or subtype of a microorganism (e.g., a virus, bacterium or fungus). For example, a “flu strain” is a certain biological form of the influenza or “flu” virus.
What is strain in physics class 11?
Strain is the measurement of how much an object is stretched or deformed due to the stress developed in the object. Strain occurs when external force is applied to an object. Complete step by step answer: When the deforming force is applied to an object, the object changes its shape.
What is strain in Wikipedia?
Strain (chemistry), a chemical stress of a molecule. Strain (injury), an injury to a muscle (tear in tendon) in which the muscle fibers tear as a result of over-stretching. Strain (mechanics), a geometrical measure of deformation representing the relative displacement between particles in a material body.
What do you mean by bacteriophage?
A bacteriophage is a type of virus that infects bacteria. In fact, the word “bacteriophage” literally means “bacteria eater,” because bacteriophages destroy their host cells. All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.
What is strain and variant?
A variant is referred to as a strain when it shows distinct physical properties. Put simply, a strain is a variant that is built differently, and so behaves differently, to its parent virus. These behavioural differences can be subtle or obvious.
What is strain in geology?
Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress. Any rock can be strained. Strain can be elastic, brittle, or ductile. Structures in geology are deformation features that result from permanent (brittle or ductile) strain.
What is strain in sociology?
strain theory, in sociology, proposal that pressure derived from social factors, such as lack of income or lack of quality education, drives individuals to commit crime.
What does phage mean in biology?
bacteriophages
Definition. Phage biology is the scientific discipline concerned with the study of all biological aspects of bacteriophages (phages), which are viruses that infect bacteria. This includes the distribution, biochemistry, physiology, cell biology, ecology, evolution and applications of phages.
What is virulent phage?
virulent phage A bacteriophage that causes the destruction of the host bacterium by lysis. Temperate phages, on the other hand, rarely cause lysis. A Dictionary of Plant Sciences.
What type of virus is coronavirus?
Coronaviruses are a type of virus. There are many different kinds, and some cause disease. A coronavirus identified in 2019, SARS-CoV-2, has caused a pandemic of respiratory illness, called COVID-19.
How is a strain diagnosed?
To diagnose a muscle strain, doctors will usually begin with a physical exam and an evaluation of your symptoms. Sometimes the doctor may have you move the affected body part to determine exactly what muscle has been strained. Certain scans such as X-rays or MRIs may be helpful for ruling out other types of injury.
How to tell the difference between a sprain and a strain?
The Medical Definition. Ligaments are bands of tissue that connect two joints together,and they’re located in all our joints.
What are the different types of strains?
A compound can experience three different types of strain: angular strain, torsional strain, and steric strain. Due to the interactions and repulsions between different molecules, a compound can consist of any, all, or none of these three strains.
