Indicate whether each statement is true or false: 1. Water can move either direction across the wall of the small intestine; osmotic gradients across the epithelium determine the direction of its movement. True 2. Because of the osmotic gradient produced as nutrients are absorbed in the small intestine, nearly all water that enters by way of the oral cavity, stomach, or intestinal secretions is excreted. True 3. Potassium, calcium, chloride, magnesium and phosphate ions all move passively through the intestinal wall of the duodenum and jejunum following positively charged sodium ions. False

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
