When someone is dying of hunger or thirst, is there a "point of no return" after which they are still alive but if they were given food or water their body would not be able to absorb it fast enough to survive?

And if this point exists, would someone who's past it still be conscious/aware?

Some human organs, e.g. liver and skin, have regenerative properties. Why don't other tissues, e.g. heart or stomach, also have similar regenerative properties as the liver and skin have?

Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science

Posted: 24 Jul 2019 08:13 AM PDT

Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science

Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...".

Asking Questions:

Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions.

The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists.

Answering Questions:

Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience.

If you would like to become a member of the AskScience panel, please refer to the information provided here.

Past AskAnythingWednesday posts can be found here.

Ask away!

Just like humans can pull muscles without proper stretching, can animals have pulled muscles with sudden movement?

What separates a “speedy” metabolism from a “slow” one?

Does a beard grow at the same rate everytime or is it impacted by factors such as sleep, health, diet, Etc?

In large timescales, energy is not conserved because of the expansion of the Universe. Given energy was conceptualized before relativity, is there a way to redefine energy to keep it conserved even with GR?

In Network Theory is their any simple way to be able to tell if you can create the network without having links overlapping each other?

Posted: 24 Jul 2019 01:46 AM PDT

basically i was wondering if it would be possible to recreate this network https://i.imgur.com/pOIwe3L.png without having the branches over lapping (as it is kind of annoying my OCD)

PS: as someone who doesnt spend to much time in this subreddit (and thus doesnt have alot of karma) having to wait 8 minutes to repost my question because the 1st time i forgot a question mark, is kind of annoying

Do all brain cells contain microtubules​?

Why is the work done during expansion greater in adiabatic process than polytropic process, but it is vice versa in case of compression?

Is the Earth's speed of rotation always constant ? What would happen if it accelerated / decelerated randomly ? Also, if the speed went up / down, what would be some of the short and long term impacts on life ?

How is military-grade napalm made? How does it compare to the homemade version with styrofoam and gasoline?

Why aren’t there more triangular shaped molecules if it is the strongest shape?

Is there any scientific reason why the magnetic north/south has to correspond with extreme temperature?

Posted: 23 Jul 2019 03:45 PM PDT

I suppose what I'm asking is if the rotation of a planet is always aligned with its magnetic field. For example, would it be possible for the equator to run north to south?

What are the differences between properties of cis and trans unsaturated fatty acids?

Posted: 23 Jul 2019 07:50 AM PDT

From what I understand cis configurations are when the two hydrogens bonded to the carbons forming the C=C double bond are facing the same direction, while trans configurations are when they face opposite directions. Is this correct?

What are the differences in properties that lead to the food industry creating trans fat products? Why are trans fatty acids more unhealthy than cis fatty acids?

Thanks in advance.
