You die after a loss of 15-25% of your body water. Water typically takes up 60% of your body. A 15lb man generally has about 11 gallons of water in his body. He'll die after losing 1.65 -2.75 gallons of water, with 9-35-8.25 gallons left inside of you. Your organs will stop functioning far before your body runs out of water.

A man can dream

That’s interesting because in humans the Y chromosome is substantially smaller than the X chromosome (all our other chromosome pairs are equally matched).

It wouldn’t be hard to imagine the Y continuing to dwindle down to nothing and then we’re just like stick bugs.

Genetics are delightfully complicated. However, even with the too simple Mendel square, you can see it happen. You put in the extra chromosome, and watch as it drops into one gamete and another ends up with the normal count.

What's really interesting is that I have found multiple examples of organisms with odd-numbered males and even-numbered females, but I can't seem to find a single odd-numbered female.

I looked it up and, stick bugs have 21 chromosomes in males and 22 in females.

Moreover, they can reproduce asexually but the offspring will be female. If they reproduce sexually, the offspring will have a 50% chance of being male.

So that answers the question. Male stick bugs have an odd number of chromosomes yet they can still have an offspring.

Even though “everyone knows” that mules are infertile, there are actually quite a few well documented cases of fertile mules. This page lists some older examples going back to the 19th century; some more recent (peer-reviewed) cases are listed in

• A fertile mule and hinny in China
• Key Aspects of Donkey and Mule Reproduction
• Fertile mule in China and her unusual foal
• Fertile mules
• A foal from a mule in Morocco

With dozens of instances being documented in spite of farmers actively trying to prevent mules and hinnies from breeding, it's likely that a fairly significant percentage (though of course a minority) of them are fertile.

There are several cases of plants with odd numbers of chromosomes, such as Homeria flavescens (2n = 9). These plants can generally (always?) reproduce through self-compatibility and autogamy, which reduces the issues of odd chromosome numbers.

There are a number of species in which the males have odd chromosome counts, such as the Indian muntjac (6 chromosomes in the female, 7 in the male).

If you have 13 important chromosomes, one of them is getting left behind when your cells divide to produce gametes.

There are insects that use haplo-diplody (spl?) where the males can have an odd number of chromosomes (n) and females have the regular diploid number (2n)

If you reproduce asexually, I can’t think of a reason why having an odd number of chromosomes would be a problem.

There are some animals where different sexes have a different number of chromosomes, and one of them is an odd number.

I had to look it up to be sure: ice does in fact expand as it gets warmer, just like most things (and unlike liquid water near freezing). https://www.engineeringtoolbox.com/ice-thermal-properties-d_576.html

Water is actually a good conductor of heat compared to gases, but not as effective as metals. However, it's still used as a coolant due to its high specific heat capacity, which allows it to absorb large amounts of heat energy without a significant temperature increase. It's also readily available and cost-effective for many applications.

None, the continents were already well formed before the Moon was placed in orbit. Right around the time the current continents arrived at their present location (Due to the expanding earth effect) the moon entered our solar system and was strategically aligned into its current orbit. Luckily due to the cooling of the mantle the earth has stopped expanding in diameter, so no significant changes to the current continental structure should occur...at least not at the rate it was expanding over the last 500,000 years.

Amazing stuff.

> if you need to turn thr magnet off you need to dump the helium

I've never worked with an MRI magnet, but in general, superconducting magnet systems can be ramped down to virtually zero without evaporating all the helium. You just need a power supply for the magnet.

I don't know if the magnet power supply comes with the MRI system though. I think in NMR spectroscopy, magnet systems are often sold without power supply. The technician who installs the system charges it with their power supply, and takes it back with them. As long as the users don't somehow empty out the helium or damage the magnet, it will hold its field indefinitely.
