The diagram below shows the movement of matter in a portion of water cycle. what does p most likely represent?
a) rivers
b)springs
c) transpiration
d) precipitation

The correct answer is B) springs.

A place on the Earth’s surface where water appears at on its own is called a spring.  After rain or from snow water seeps into the ground. The water which seeps into the ground is collected in fractures and fissures in the bedrock. Water in the bedrock collected into the aquifers. When a fissure in the bedrock breaks the surface, the natural high water pressure under ground forces water above the earth surface and forms spring.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
