Single celled organisms are able to maintain homeostasis, withstanding relatively large alterations in their external environments . This is due to the fact that they posses structures that regulate and carry out life functions. They perform all the functions that are necessary for an organism to exist.
The ability to obtain all the substances that are essential for their existence eliminates the need for dependence on other cells. These single-celled organisms are thus able to maintain a relative state of equilibrium within their internal environment.

Personally i have experienced that microbes living in saline condition were isolated from soil and grown them on Lauria Bertani media.
Answer:
The stratosphere
contains the ozone layer
,
is used by airplanes,
has strong, steady winds
, and
increases in temperature as altitude increases
.
Explanation:
The stratosphere is the atmospheric layer between 10 km and 50 km above the Earth's surface.
It includes the ozone layer, which is at an altitude of about 20 km.
It has strong, steady winds that can reach as high as 220 km/h.
Passenger aircraft generally fly in the lower levels of the stratosphere, at altitudes of about 10 km to 12 km.
Temperatures increase with altitude, from -50 °C at 10 km to -3 °C at 50 km.
A is wrong. The mesosphere (altitude 50 km to 85 km) is the coldest of the atmospheric layers, with temperatures as low as -90 °C at 85 km.
Answer:
Explanation:
The near-surface open water surrounded by the littoral zone is the limnetic zone. The limnetic zone is well-lighted (like the littoral zone) and is dominated by plankton, both phytoplankton and zooplankton. Plankton are small organisms that play a crucial role in the food chain.
No because if your body has never experienced it before it will not no what to do and most likely the body will just send out/produce the other common antibodies or cells
