Describe how the intermolecular forces involved with RNA solubility are different from proteins and lipids (
almond37 [142]

Answer:

Due to strong forces between solutes and solvent, solubility increases.

Explanation:

Due to intermolecular forces, RNA solubility is higher than the solubility of proteins and lipids because intermolecular forces enables RNA soluble in water due to its polar nature while on the other hand, proteins and lipids are not very soluble in water due to their non-polar nature. If the intermolecular forces are stronger between solute and solvent molecule, the greater the solubility of the solute in the solvent and vice versa.

Explain how hormones, nervous system stimulation, and the volume, chemical composition, and osmolarity of the chyme affect motil
Solnce55 [7]

Genetics are thought to play a role in certain gastric motility disorders, such as hirschusprung's disease , intestinal pseudo- obstruction and GERD.

Hormones which controls the different digestive enzymes that secreted in stomach and the intestine during the process of digestion and absorption. Stomach secret the acid in response to food intake which is stopped by the somatostain. This stimulates the gastric mobility.

Duodenum mobility is effect by the input form the central nervous system which reduce the propagation velocity and increase contractile amplitudes. (CRF) Corticopin -releasing factor is physiologic mediator of stress effects on the gut. An antroduodenal mobility is diagnosis problem in the muscles of stomach and small intestine are working.
