<span>The number of electrons in the valence shell of an element is the principal determinant factor of the kind of chemical bonding it will be involved in. For an element that has only one electron in its outermost shell, such an element will donate the electron to another element which need only one electron. Thus, such an element will undergoes electrovalent bonding. For an element which have four electrons in its outermost shell, such element will prefer to share the electrons will other elements who need such in order to become stable, thus, such element will undergo covalent bonding.</span>
Nucleic acid is the answer
Answer:
The correct answer is "True".
Explanation:
It is true that the major role of absorption in the ileum is to reclaim bile salts to be recycled back to the liver. The ileum is the final part of the small intestine, serving as the terminator of the ileocecal sphincter. The ileum is the final step of absorption in the small intestine and while most nutrients are absorbed in the jejunum, the ileum absorbs the bile salts and some vitamins, like vitamin B12.
