Calcium oxide is a basic oxide because when metals reat with oxygen they form basic oxides
I am not sure what the answer is
<span>Alanine is one of the simplest amino acids in terms of molecular structure and one of the most widely found in protein. In humans, the L-isomer, which is the only form that is involved in protein synthesis, is one of the 20 standard amino acids required for normal functioning. Alanine is classified as a nonpolar amino acid.</span>
<span>The
answer is facilitated diffusion. It requires no energy because the ions are
traveling down the concentration
gradient. Facilitated diffusion is important
for the regulation of ions in a cell. It also enables
ions to pass across the hydrophobic layer of the cell membrane composed
of phospholipids.</span>
