One is the presence of villi and microvilli in the small intestines
that increase the surface area for which food is absorbed. Second is the presence
of goblet cells that secrete mucus to prevent self-digestion of the
tract lining. Another is the specialized enzymes in different regions of the digestive tract
that specialize in digesting particular foods.
<span><span>As for the responder, science study as much as it can
process. Though there are certain principles, theories and laws needed to
determine one is truly science. It needs to undergo the scientific method to
analyze and gather evidential data and in addition this study should be
replicable in the process. Replicable is one strong characteristic of a study
that can intensify the reliability and validity of the field. And what science
doesn’t study is not until the principles apply to the aforementioned
statement. Science can study and wants to understand everything or in as much
as the broader scope of each phenomenon, it’s some concepts that are just very
hard to gather data, and studies like the metaphysical and paranormal that can’t
be repeated. These limitations inhibit scientists to draw data that is reliable
and valid, thus, science. </span> </span>
Answer:

Actin is a family of globular proteins that form microfilaments, one of the three fundamental components of the cytoskeleton of the cells of eukaryotic organisms (also called eukaryotes). It can be found as a monomer in free form, called actin G, or as part of linear polymers called microfilaments or actin F, which are essential for cellular functions as important as cell mobility and contraction during cell division.
