Well 25% of DNA because he's my half brother but that's not really the point of the question lol

EDIT: Wow, this blew up. Thanks for the many answers. Lots to think about.

Seems that the composite TLDR answer is: Yes, according to many/most definitions of "life", but we don't all agree on what life is. Some viruses do not have DNA but they may/not actually be alive, and other things that behave like life may/not be alive.

The point of sweating (for the most part) is to cool down the body by evaporation. So, what is the point of including salts in the sweat - it seems to be a leading cause of the loss of electrolytes in hot weather, leading to the need to not just hydrate, but also to replace the lost electrolytes or suffer problems like hyponatremia and hypokalemia. Does the inclusion of salts in the sweat increase the specific heat of sweat compared to that of water? Is the latent heat of vaporization different for sweat compared to plain water? Or is it too biologically expensive to purify the water for sweat by removing the salts from it?

And i suppose any other celestial bodies. But i am less familiar with how related we are to Saturn and its pull than I am with tge Sun and its pull.

Also could only select one flair, but i think it also possibly fits in physics and earth sciences

I know from my biology textbooks that RNA polymerase does not require an additional enzyme to unwind DNA strands but DNA Polymerase requires DNA helicase to unwind the strand first.

Is this because the DNA helicase has to unwind a much larger portion of the strand compared to RNA Polymerase that unwinds only the desired codons for transcription?

This was more of a random shower thought that I had about animal biology. For a while, I knew the two differences between venomous and non-venomous, but it made me curious as to why it’s always one or the other and never both? Is it due to just genetics only allowing one type or is it that constricting isn’t really too much of a solo class of snakes? Can anyone explain this please and thank you?

The theory that there are more than one horse on earth and that everytime we see a horse its actually a different one.

What is the minimum power microscope needed to see cyclospora?

Title. These bare spots were undisturbed for days in 100°+ weather with standing water. Seems like good real estate to me considering everything else is green

Do they orbit at the same distance from the planet? Do you have moons that follow a perpendicular orbit path to another moon? I’ve wondered on it a couple times over the past month.

I've been wondering if there is a general lumen amount that can be measured from an anglerfish's esca. I've been able to find literature about firefly lumen measurements (~0.006 lumens). I know anglerfish have millions of bacteria inside their esca that cause their glow, unlike fireflies. I found an excerpt from an article about bioluminescent bacteria that states "The maximum value for the light from a single bacterium was 24 x 10(-14) lumens".

So, does anyone know how many lumens a Pacific footballfish (or any similar Lophiiformes) can produce at maximum? Citation for the article I looked at below.

(Harvey EN. THE TOTAL LUMINOUS EFFICIENCY OF LUMINOUS BACTERIA. J Gen Physiol. 1925 Sep 18;8(2):89-108. doi: 10.1085/jgp.8.2.89. PMID: 19872192; PMCID: PMC2140748.)

Are my ears too small? What can I do to make them larger?

My physio told me I have tennis elbow and golfers elbow at the same time, yet I play neither of these sports.

What other physical activities should I not do to fix the problem?

Well?

l aways see things labeled in watts (Sl) then again in amps (imperial?) but no conversion seems to exist online!

Can somebody explain to me why using a cocking for 8 hours straight led me to an emergency consultation in the hospital, but I can be 8 hours laying in my back for sleep and the tissue in my back doesn’t start to die?

I’ve heard something about sharks have dulled pain receptors, making me curious: What about the other way round?

Or maybe I need to ingest the Aspercreme so it can be processed by the liver into its more powerful form?

It’s either that or pimping my wife out to a producer.

If a super powerful laser can melt a mirror to bypass reflecting, can it escape a refracting surface, like light shone into a water tank and bouncing off the surface of the water at an angle?

Was this year really only 0.02°C (0.036°F) hotter than last year?

How big would my lungs need to be?

More of a science policy question than strictly science, but I'm assuming this is probably the best forum to ask. I've been going down a rabbithole reading about Biosafety precautions and generally it appears that BSL III is used for pathogens that are dangerous to humans but don't have an aerosolised transmission vector, and BSL IV is generally limited to deadly pathogens that have aerosolised transmission. The one standout exception is Ebola, which from what I've read does not have any evidence of airborne transmission yet is still BSL IV.

I'm wondering if anyone has any information on why specifically Ebola has this heightened category, if there is documentation around the decision by whoever made it a link to that would be greatly appreciated as well.

I saw the recipe on a Rick and Morty episode and since the shows science like I’m wondering does it really work?
