Water then moves from cell to cell through the root cortex by osmosisalong a concentration gradient; this means that each cell is hypertonic to the one before it. In the centre of the root the water enters the xylem vessels. Water may move by diffusionthrough the cell walls and intercellular spaces.
<span>Villi are hair-like structures covered with epithelial cells measuring 1.5 mm that line the mucous inner membrane of the small intestine. The epithelial cells of the villi contain microvilli and are responsible for the absorption of nutrients. Being so small and numerous, they effectively increase the absorptive surface area of the small intestine. When the surface area increases, this is the time they absorb the nutrients.
As for plants' root hair cells, they receive nutrients through osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water and minerals are transported through the roots to the rest of the plant where it is used for different purposes: It is a reactant used in photosynthesis.
As we can see, both of them utilize increasing their surface area.</span>
Answer:
Gastro-esophageal reflux disease is a disease in which the upset stomach causes re-flux of acid back to esophagus. This may produce highly uncomfortable feeling of chest burn that may last even for two hours. GERD can get worse after eating because more volume of acids are released by stomach on detection of food like fast food and food that have high protein content. Patients are recommended to lose weight because that loses the pressure on abdomen a decreases the chance of GERD. Head elevation is also recommended to keep the acid within the stomach. It is same in while sitting upright after eating is recommended by doctors. GERD symptoms may have some respiratory complications like lung inflammation and chest congestion due to the action of stomach acid. This may lead to asthama.
