b. It assists in the absorption of monosaccarides, amino acids, vitamins, and other nutrients by the cells in the intestinal lining.
c. It makes lipids accessible to the water-soluble enzymes.
d. It helps feed intestinal flora that aid in the digestion process, particularly in the large intestine.

Why do the same trans-regulatory elements lead to very different morphology in different species of organisms?
A. Different species have genetic codes that use different codons, leading to different amino acid sequences. B. Morphological change depends on sequence mutations in enhancers. C.
