In examining a protein molecule, you discover that it has not folded properly. Why is this alarming? This may impact the function of the protein, possibly causing disease or allergies.
This may impact the function of the protein, possible causing it to replicate multiple times.
This may result in the protein forming bonds with additional amino acids.
This may result in the protein forming bonds with lipids instead of other proteins.
This may result in the protein forming bonds with steroids, thus changing the hormonal function of the cells.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
