Ways an organism can survive in extreme conditions.

Lets ay there is a 0.5 Earth mass and 0.8 Earth radii planet orbiting a Sun like star at the same distance Earth is orbiting its Sun. Its atmospheric pressure would be 0.03 bar. Water boils at 75 degrees F at this pressure. How could an organism living on the surface survive?

Another question...Lets say the organisms body temperature was 80 degrees F.

Would the water within the organism boil off due to the low atmospheric pressure or could the outside pressure have no affect? If it could be prevented how?

It could survive by being adapted to it's environment or by using an artificial environment.

To have a body temp of 80F, and rely on liquid water to survive, would probably mean being able to maintain a high internal body pressure too. It could also live in a cooler region with liquid water on the surface and just have a large throughput (it would take a while for the water just drunk to boil). Maybe the organism acts as a biological steam engine? Or maybe it has an external bladder to store liquid water? Basically you can take your pick - bearing in mind that speculation is against the rules.

What is the scientific context for the question?

I am just very curious how an organism could survive in an extreme environment. Thanks I never even imagined an organism could do those things.

Really? - Then you should look at how Earth organisms survive the range of environments offered on our own planet. Life is pretty tenacious.

Note: "organism" covers everything from a virus to a colony of fungus to an Apatosaur.
It includes all such things currently living and extinct and yet to be. That gives quite a lot of scope for finding a solution.

I would like to provide a response to the question of how an organism could survive on a planet with extreme conditions, specifically a 0.5 Earth mass and 0.8 Earth radii planet orbiting a Sun-like star with an atmospheric pressure of 0.03 bar, where water boils at 75 degrees F.

Firstly, it is important to note that the survival of any organism on a planet with such extreme conditions would depend on several factors, including the organism's adaptation to the environment and its ability to regulate its internal temperature. However, there are some general ways in which an organism could potentially survive in this scenario.

One possible adaptation is the development of specialized structures or behaviors that can withstand or regulate the extreme temperatures and low atmospheric pressure. For example, the organism could have a thick and insulating outer layer to protect itself from the harsh environment. It could also have a specialized respiratory system that can extract oxygen from the thin atmosphere and efficiently remove excess heat from its body.

Another important factor for survival would be the availability of resources such as food, water, and shelter. If the planet has a limited supply of these resources, the organism would need to have efficient ways of obtaining and conserving them. For instance, it could have a slow metabolic rate to conserve energy and require less food and water. Alternatively, it could have a specialized diet that allows it to extract nutrients from the available resources in the environment.

Now, moving onto the second question about an organism with a body temperature of 80 degrees F on this planet. It is possible that the low atmospheric pressure could affect the water within the organism's body and cause it to boil off. However, this would depend on the organism's ability to regulate its internal temperature and the composition of its body fluids.

If the organism has a way to maintain its body temperature at 80 degrees F, such as through specialized physiological processes or behaviors, then it is likely that the water within its body would not boil off. On the other hand, if the organism cannot regulate its internal temperature, then it would be more susceptible to the effects of the low atmospheric pressure. In this case, the organism could potentially adapt by having a higher concentration of solutes in its body fluids, which would lower the boiling point of water and prevent it from boiling off.

In conclusion, an organism could potentially survive on a planet with extreme conditions by adapting to the environment and having specialized structures,
