heat strain or the thermal strain is caused due to the temperature changes. A solid body expands as the temperature increases and contracts as the temperature decreases.this causes the thermal strain. for a homogeneous and isotropic body the thermal strain is caused by change in temperature. thermal strain = coefficient of linear thermal expansion * change in temperature
where the coefficient of linear thermal expansion gives the strain per degree of temperature.

How did oswlad Avery identify the molecule that transformed the R strain of bacteria into the S strain?
Oswald Avery identified the transforming molecule by conducting a series of experiments using heat-killed S strain bacteria and live R strain bacteria. He systematically purified the components of the heat-killed S strain and tested each one for its ability to transform R strain bacteria into the virulent S strain. Avery found that only the DNA from the S strain could induce the transformation, leading him to conclude that DNA is the hereditary material responsible for this transformation. His work provided crucial evidence for the role of DNA in genetics.
What is the molecule that caused transformation in Griffith's mouse experiment?
The molecule that caused transformation in Griffith's mouse experiment was DNA. When heat-killed S strain bacteria (which had DNA) were mixed with live R strain bacteria (which did not), the DNA from the dead S strain bacteria was able to transfer genetic information to the live R strain bacteria, making them pathogenic.
Is hydrocarbon paraffin or propane is better fuel?
I would have to say cyclopropane because of increased bond strain.
What planets and moons have volcanism?
venus - active volcanos injecting sulfate into atmosphere, heat from radioactive decayearth - active volcanos, heat from radioactive decaymars - extinct volcanos, no activity in milllion of years, heat from radioactive decayio - active volcanos, heat from mechanical strain from orbit shapeThere are probably others.
What is transformed from rough strain bacteria to smooth strain cells?
The process of transforming rough strain bacteria into smooth strain cells involves transferring genetic material - specifically a capsule gene - from a smooth strain to the rough strain. This genetic transfer results in the expression of a protective capsule on the surface of the rough strain cells, converting them into smooth strain cells with enhanced virulence.
How to apply Moist heat to strain?
To apply moist heat to a strain, you can fill a hot water bottle and place a damp towel around the bottle. The towel will pick up the heat from the water bottle and you can rest both on your strain.
Should you use heat on a strain?
Ice
What are 4 steps in Griffith's experiments?
S Strain ---> inject into mice ---> Mice Die R Strain ---> inject into mice ---> Mice Live Griffith was able to kill bacteria by heating them. He observed that heat-killed S Strain bacteria injected into mice did not kill them. When he S Strain (heat Killed) ---> Injected into mice ---> Mice Live S Strain ( heat Killed) + R Strain (Live) ---> Injected into mice ---> Mice Die
What happens when heat-killed S-strain pneumococcus were injected into a mouse along with live R-strain pneumococcus?
A very important characteristic about bacteria actually created live S-strain to exist in the dead injected mouse. Bacteria is competent, in biological terms, meaning that cells can take up "naked" DNA from it's environment. Knowing that fact, when the heat-killed S-strain pneumoccus mixed with the live R-strain, the R-strain took in the DNA, therefore inheriting the deadly coating of the S-strain. So the R became S, and killed the mouse.
Why did the rough strain and heat killed smooth strain kill the miceAsk us anything?
The rough strain of bacteria is non-virulent and does not cause disease, while the smooth strain is virulent due to its protective capsule. When the heat-killed smooth strain was introduced to the mice, it released its genetic material, which could be taken up by the rough strain through a process called transformation. This allowed the rough strain to acquire the virulence factors from the smooth strain, making it capable of causing disease and ultimately killing the mice. This phenomenon demonstrated the principle of bacterial transformation and the transfer of genetic traits.
When Fredrick griffith injected mice with a mixture of both heat killed smooth strain bacteria and live rough strain bacteria an unexpected result occured this result was?
The unexpected result was that the previously harmless rough strain bacteria were able to take up genetic material from the heat-killed smooth strain bacteria, becoming virulent. This demonstrated the concept of bacterial transformation and laid the foundation for understanding DNA as the genetic material.
How does heat strain affect the human body during physical activity?
Heat strain during physical activity can lead to dehydration, heat exhaustion, and heat stroke. These conditions can cause symptoms such as fatigue, dizziness, nausea, and in severe cases, organ damage or even death. It is important to stay hydrated and take breaks in a cool environment to prevent heat-related illnesses.
What does lassitude mean?
tired from overwork or strain or heat; lack of energy; listlessness; feeling lazy
Strain energy definitions?
Strain energy is a form of potential energy. Work done to distort an elastic member is stored as strain energy. Some energy may be lost in plastic deformation of the member and some may be converted into heat instead of stored as strain energy, but the rest is recoverable. A spring is an example of a storage device for strain energy.
What actors and actresses appeared in Havasu Heat - 1998?
The cast of Havasu Heat - 1998 includes: Vince Cannon Julie Strain James Van Patten
What is the molecule that caused transformation in Griffith's mouse experiment?

What was the variable in Oswald Avery's experiment?
The variable in Oswald Avery's experiment was the type of enzyme used to break down the polysaccharide capsule in the heat-killed S strain bacteria. By using different enzymes, Avery was able to determine which specific molecule was responsible for transforming the R strain bacteria into the pathogenic S strain.
