Answer:
D. archaeal membranes contain L-glycerol.
Explanation:
Archaea and eubacteria differ from each other with respect to the nature of membrane lipids. Lipids present in the membranes of the archaeans have the hydrocarbons derived from isoprene units. These hydrocarbons are branched and are attached to the glycerol with help of ether linkage. Ester linkages are present in eubacteria. The glycerol present in the archaeans is L- glycerol. Bacterial membranes have D-glycerol present in their lipids.
Deficient Fluid Volume is the nursing diagnosis that is most likely to apply to a patient who has a dysfunction of the posterior lobe of the pituitary gland.
The posterior pituitary produces ADH; disruptions in the levels of ADH upset the body's normal fluid balance. The hormones produced by the posterior pituitary do not directly affect immune function, tissue perfusion, or body temp.
Deficient fluid volume, or hypovolemia, results from a loss of body fluid or fluid shift, causing the fluid output to surpass fluid intake. In this process (acute or chronic), the body loses fluid volume and electrolytes. The source for this condition can be gastrointestinal, renal, or even metabolic.
Symptoms:
- Expresses feeling thirsty
- Verbalizes feelings of weakness
- States feeling dizzy/lightheaded, especially when changing position
- Complains about an inability to focus
- Complains of headaches
- Describes feeling of fast heartbeat
