A phospholipid is an amphipathic molecule, meaning it has a hydrophobic part and a hydrophilic part. The fatty acid chains are hydrophobic and do not interact with water, whereas the phosphate-containing group is hydrophilic (because of its charge) and interacts readily with water.
Homeostasis is maintained through negative feedbacks. As changes in the environment push a system property from its equilibrium, negative feedbacks counteract the. Change in environment. Change in environment.
The correct answer is: nurse should provide fluids to patient (rehydratration).
Sickle cell anemia is a genetic disorder caused by a mutation in the gene which encodes for hemoglobin (oxygen carrying protein). Patients with this disorder often experience vaso-occlusive crisis (VOC), condition caused by the blockage of small blood vessels. Oxygen supply to the tissue is blocked and that causes pain and injuries. VOC is usually triggered by dehidratation, so, rehydration is recommended. Oxygen therapy and opioids use are also the way for VOC treatment.
