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.

Estrogen is most likely to exert its effect by regulating
vekshin1

Answer:

c) expression of genes and production of  specific proteins.

Explanation:

Estrogen is a lipid-soluble steroid hormone that diffuses through the lipid bilayer of the plasma membrane of its target cell. The hormone binds to its nuclear receptor and receptor-hormone complex then alters the expression of particular genes.

It triggers transcription of specific DNA sequences into mRNA which in turn enters the cytoplasm and serves as a template for synthesis of specific proteins.

Estrogen is the female sex hormone and stimulates development of secondary sexual characters in females as well as required for maturation of egg.
