Stage II – Formulating a hypothesis
Stage III – Collecting the data

Stage V – Finding a solution or reaching a conclusion
Lichens are the photosynthetic organisms.
<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
<span>Suffocation is a most leading reason of death in grain storage
bins. Grain handling industry is a high hazard industry where workers can be
exposed to numerous serious and life threatening hazards. These hazards
include: fires and explosions from grain dust accumulation, suffocation from
engulfment and entrapment in grain bins, falls from heights and crushing
injuries and amputations from grain handling equipment. </span>
