Cultures of a bacterial species were incubated on the shelf of a refrigerator, out on a lab bench top. on the shelf of a 37" c incubator, and on the shelf of a 50" c incubator. after incubation, there was no growth at 37°c and so. c, very little growth out on the bench top, and abundant growth at refrigeration. what tem could be used for this species?
a. halophile
b. mesophile
c. anaerobe
d. psychrophile
e. thermophile

D. Psychrophile

Explanation:

A psychrophile refers to the microorganism that can grow well at 0°C. These microbes have an optimum growth temperature of 15°C or lower. They can tolerate a temperature maximum of around 20°C but show inhibition of growth above that temperature. Some of the examples of psychrophile are Bacillus psychrophilus, Chlamydomonas nivalis. Psychrophiles are naturally found in Arctic and Antarctic habitats. According to the given information, the culture of the bacterial species was able to grow well at refrigeration and therefore, they are psychrophile.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
