Answer:

Because it forms beta arrangements subsecuently forming microfibrils

Explanation:

Cellulose is a complex carbohydrate formed by a long polysaccharide of glucose molecules with <em>beta arrangements, these give a flat and rigid structure that held to each other through hydrogen bonds forming microfibrils that give their rigidity to the cell walls</em> (you can see this structure in the image added).

slava [35]

Low-density lipoproteins (LDLs) can contribute to the build-up of plaque that narrows blood vessels; however, LDLs are necessary because they are used to synthesize  eicosanoid

<h3><u>Explanation:</u></h3>

The article eicosanoid is practiced to include those biologically effective lipid intercessors obtained essentially from C20 fatty acids. The 'actual' eicosanoids are provided enzymatically with high stereochemical accuracy, and this is necessary for their biological purposes.

Biosynthesis of eicosanoids concerns the progress of multiple enzymes. Eicosanoids are produced largely from unesterified fatty acids, no the CoA esters, and they work in this kind, but it is frequently noticed that they may transpire and some may admittedly be incorporated while esterified to other lipids.

What specific part of the brain processes nerve impulses from touch and pain receptors?
pogonyaev
TOuch and pain are controlled by different regions of the brain, so I gonna treat these terms separately:

PAIN: one thing seems certain: there is no single "pain centre" whose only activity could account for all facets of pain. In other words, no lobotomy of any particular region of the brain completely removes the pain. So there are many regions that are responsible for pain: The reticular formation and the thalamus (specifically the Deep lemniscal territory) which is responsible for both touch and pain sensations

TOUCH: touch sensation are processed by parietal lobe in the brain cortex (which is also responsible for sight and hearing), and the deep lemniscal territory in the thalamus.

muscularis externa

The answer is muscularis externa. This layer is one of the 4 layers (tunics) of the GI tract. It is found beneath the submucosa and is composed of smooth muscles. The smooth muscles are responsible for the involuntary movements called peristalsis, that move food along the gastrointestinal tract.
