PH is a measure of how acidic<span>/basic water is. The range goes from 0 - 14, with 7 being </span>neutral<span>. pHs of less than 7 indicate </span>acidity<span>, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl </span>ions<span> in the water.</span>
D) it has to depend on the type of crypt
Well, considering that seagulls, bears, and cows are warm blooded mammals, and spiders are arachnids with an exoskeleton, I'm willing to bet that spiders are ectothermic. And isn't the word exothermic?
The diversity of proteins is caused by the mRNA codons and DNA.
DNA has sequences that mRNA finds the pair for (ex. DNA says AGC, RNA says UCG)
with that, they only come in 3 nucleotide increments. which is a codon
one you have a codon, it goes thru tRNA to come out with an amino acid and a bunch of amino acids makes a polypeptide or protein
It all depends on what the DNA's code says to make...
DNA says AUG, RNA makes that UAC which is the amino acid tyrosine
did I help?
so basically 7
