Describe an experiment to test the effect of changing the acid concentration. You should include: • a diagram showing how you could catch the gas from the reaction
• how you could use the
collected gas to measure the rate of the reaction, not just how long the reaction lasts
• how you would decide which acid concentration gave you the fastest reaction

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later.when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )

If the rna molecule in a human has the nucleotide sequence of guu, this would the amino acid valine would be needed to make the protein. how would this cha process was occurring in a mushroom?

First idea: suddenly, women were leaving their homes to cycle and socialize on country roads and city streets. —wheels of change, sue macy second idea: it was not a stretch for some cyclists to see the possibility of a larger role for women in the world. —wheels of change, sue macy what type of graphic organizer would best represent the connection between these two ideas? 1) a t-chart that separates ideas into two different categories 2) a chronology that shows 3) a sequence of several events a cause-and-effect graphic that shows how one idea led to another 4)a problem-solution graphic that presents a problem and a solution to the problem
