A theory that states that only the organism with traits that are useful to the environment survive. For example, short-neck giraffes would’ve died out years ago as they can’t reach the trees nor eat grass on the ground.
hydrophobic is the resistance of water (doesn’t mix). the lipid tails are hydrophobic.
Because water can absorb and transfer heat well, the human body uses it to stabilize temperature. Water has a relatively high heat capacity, meaning it can absorb a lot of heat before its temperature rises. ... Water also helps expel excess heat from the body as water vapor from the lungs and sweat on the skin.
The first sentence is the answer and the other ore explanation
It would be nice to see the 4 stages titled to have a clue to what they could be. You see, chemical evolution is a myth, like Darwin's "warm little ponds." There are no naturalistic processes that have any power to accomplish the complex, diverse, extensive and highly non-entropic assembly of biochemical elements, molecules and assemblies into even the simplest life.
There is no primordial soup, panspermia is a distraction, none of the intractable issues for the origin of life.
Logically, the first step is collection of all elements, second, first level assembly of amino acids lipid membranes, proteins, third, higher level combination of biochemical molecules and generation of nucleotide coded DNA containing the processing code for generation and production of RNA, enzymes ribozymes and all other cellular functions, then fourth, the execution of all metabolism, nutrient collection, waste elimination and reproduction consistent with a living organism. Admittedly speculative since chemical evolution is a myth.
