Which bacteria grew in the widest range of temperatures?
a.) p. fluorescens
b.) b. gloibporus
c.) b. stearothermophilus
d.) e. oli

The correct option is : c.) B. stearothermophilus

Explanation:

Geobacillus stearothermophilus, earlier known as B. stearothermophilus or Bacillus stearothermophilus, is a Gram-positive bacteria. This bacterium is present in soil, ocean sediment, hot springs and it is also known to be responsible for food spoilage, as it can grow in a wide temperature range of 30 to 75°C. Therefore, it is called a thermophile.

A thermophile is an organism which can grow in high temperature conditions, typically between 41 and 122 °C.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
