<h2>GFR </h2>
Explanation:
A decrease in GFR will cause lower Na and Cl ion concentration in the distal tubule
- GFR stands for Glomerular Filtration Rate
- The rate at which kidneys filter blood is called the glomerular filtration rate
- The main driving force for the filtering process, or outward pressure is the blood pressure as it enters the glomerulus which is counteracted to some extent by inward pressure due to the hydrostatic pressure of the fluid within the urinary space, and the pressure generated by the proteins left in the capillaries that tend to pull water back into the circulatory system (colloidal osmotic pressure)
- The net filtration pressure is the outward pressure minus the inward pressure
 
        
        
        
Answer:
They have  helical thickening of lignin in their walls to prevent collapse
Explanation:
the primary function of Xylem and its conducting vessels tracheids is to provide  support and tranport  water and  minerals  in plants.
 Xylem vessels  have layers of dead materials in the walls called LIGNIN.   Lignin is a polymer; a  very strong, hard materials that stop water passage  through it,because it contains dead cells, 
Therefore  the presence of  deposit of these strong  impermeable, ligified  walls  in its  walls  prevent its collapse during mass flow of water of transpiration pull.

It can be expected that there
will be closure of the patent ductus arteriosus for this is the effect of
indomethacin. The adverse effect would include platelet dysfunction, decrease
gasto-intestinal motility and an increase in necrotizing enterocolitis. With this,
the nurse should anticipate the possible outcomes where there will be increase
bleeding time and decrease gastro-intestinal function after giving
indomethacin.
