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.
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.
I would have to say cyclopropane because of increased bond strain.
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.
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.
strain and sprain involves the ligaments
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.

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
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.
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.
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.
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.
tired from overwork or strain or heat; lack of energy; listlessness; feeling lazy
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.

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.
