Which steps are important when designing and conducting a scientific experiment? Hide the results from fellow scientists. Identify the independent variable. Eliminate all dependent variables. Address any confounding variables. Form a non-falsifiable hypothesis.

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? )

For each of the following, decide whether the statement describes photosynthesis, cellular respiration, or both. releases energy in the form of atp. stores energy in glucose molecules. performed by producers. performed by consumers.

Of seawater increases with decrease in the temperature. therefore, the cold water sinks to the deeper layers at the bottom
