Aliun [14]

Answer:

time; point

Explanation:

The complete question is as follows:

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death __________ whereas the lowest temperature required to kill all microbes in a sample within 10 minutes is the thermal death _________.

time; point

window; point

point; time

time; temperature

  • When a population of bacteria gets killed due to exposure to high temperatures then this is termed as thermal death.
  • The time taken to kill a specific microbe at a specific temperature is termed as the thermal death time. The length of the time taken depends on the nature of the target microbe and hence, varies from one to another.
  • The lowest temperature that will kill all the microbes in a sample within ten minutes is defined as the thermal death point. The temperature at which the microbes get killed within 10 minutes also varies from one microbe to another.
  • Thermal death results in the disruption of the cell membranes of the microbes and hence can kill the microbes.
