[@RicardoPetinga]

Do they even have normal sweat? If not, I'd assume it would be "blood, blood-sweat and tears". Which, despite them putting all their passion into it, would mean the project was easy for them. Because... no sweat. I'll see myself out.

[@geekfreak2000]

It would just be "blood-sweat and tears" only two ingredients. Like instead of " milk, powder, and egg" ---> "milk-powder and egg" The blood describes the sweat

I’ve never, ever considered the absence of external testes on cetaceans and hippos. It’s a reasonable question. I imagine a conversation on an exploratory vessel: Erudite early observational natural scientist: “This male right whale, in fact, shares many characteristics with hippopotami, in the darkest regions of-“ Drunken seaman: “Yo.

LOL☄️ "ponies are important too"( Gilda Radner w,/ Chevy Chase in a skit about NATURAL "RACE HORSES'🙄. Animals are ZooCOOL but do not forget those PRODUCERS assembling their long chain carbon nutrients like lipids, protiens and carbohydrates which move up food chains. Plants, even before becoming vascular (moss/Bryophyta,) were PRIMARY PRODUCERS. PHOTOSYNTHETIC PLANTS AND ALGAE which forged symbiotic relations with eukatyotic Fungi in tradeoff deals. Those organisms that assemble the SUN ENERGY - CAPTURING PIGMENT that feed herbivores whom feed carnivores who in turn die and feed something and whose metabolic waste (SERVES TO SPREAD PLANT SEEDS TOO,,) ... something..... central Magnesium atom (like mammals' hemoglobin with a central Iron atom designed for a very SPECIFIC function that so many organisms need - ESP. humans in Himalayas and Andes🤔 [bond, carry & release O2 between tissues). Blood is red from Oxygen INTERACTION. It has a long chain phytol tail much like Carotenoid pigments (red. Then chlorophylls are green, xanthins are yellow and cyanins are blue). SEE THAT ALL IS INTERCONNECTED, INTERDEPENDANT??? Nearly irreducible complexity. So love the monera, archaea, plantae, fungi protista and animaliae each SOME but cuddle animals dinesticate NO MORE!

Isn't fat meant to store nutrients. And if bones are so easies digest and get nutrients out how come their often the last of the remains

[@Aaaaaliceee]

Bone is your calcium store, so if you are deficient, your body can get the bones to release and use that calcium. This is done via signals that trigger cells to do this. It is a different process to decomposition of remains. Fat is your store of energy. If you are starving, and therefore low on energy, the fat can be converted to energy.
