A small generic section of the primary structure of an α helix is given by − amino acid 1 − amino acid 2 − amino acid 3 − amino acid 4 − amino acid 5 − amino acid 6 − amino acid 7 − −amino acid1−amino acid2−amino acid3−amino acid4−amino acid5−amino acid6−amino acid7− Which amino acid residue's backbone forms a hydrogen bond with the backbone of the first ( 1 st ) (1st) residue

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
