What function does bile play during digestion?
a. It further breaks down proteins in the gall bladder.
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.
c. It makes lipids accessible to the water-soluble enzymes.
Bile—which is produced by the liver and stored in the gall bladder—makes lipids more accessible to water-soluble enzymes.

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. These regulatory elements have no effect on morphology, only metabolism. D. The transcription factor activates different combinations of enhancers and downstream genes. E. The trans-regulatory elements in different lineages have independently evolved the same sequence, by convergent evolution.
