What is one way the circulatory system maintains homeostasis? It controls blood flow to regulate body temperature. It is respons
ible for the exchange of gases between the body and the outside air. It increases the size of the chest cavity, which decreases air pressure inside the lungs. It brings oxygen into the lungs and releases carbon dioxide through the nose.
Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
Halophiles prefer high salt concentration.
Mesophiles prefer temperatures with a average of 37 degree Celsius.
Anaerobes grow in absence of oxygen.
In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.
