stimulate the nerve? The action potential increases slightly because the nerve consists of more than one neuron‚ therefore increasing the voltage increases the number of neurons that are stimulated causing depolarization of most of the neurons 6. If you were to spend a lot of time studying nerve physiology in the laboratory‚ what type of stimulus would use‚ and why? If I spent time studying nerve physiology in a lab‚ I would use electrical stimulus. Using electrical stimulus 7. Why does

Sometimes the data we need may not be available from internal or external sources. In such cases‚ we may have to obtain data by conducting our own survey or experiment. In a survey‚ we do not exercise any control over the factors when we collect information. For example‚ if we want to collect data on the money various families spent last month on clothes‚ we will ask each of the families included in the survey how much it spent last month on clothes. Then we will record this information. A survey

level. The objective of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane one ‚ polyamide film ( AFC 40 ) as membrane two ‚ cellulose acetate (CA 202 ) as the third membrane and PVDF (FP 100 ) that act as the fourth membrane. In order to identify the characteristic of all four membranes‚ experimental procedures should be done. The variable for this experiment is the membrane maximum inlet

Biology College of Science De La Salle University – Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by

choosing the pain of discipline over the ease of distraction. And that’s exactly what delayed gratification is all about” I think that is very true. Delayed gratification is just waiting for something better. If a kid doesn’t pass the marshmallow experiment parents start to wonder what they should do. Mischel states he would remind the parents that there are a large number of cognitive skills that can be used and practiced if kids have a serious self-control problem. At one point Mischel used poker

Results Our experiment showed that Rayovac outlasted all of the other batteries we tested by at more than two hours. The Eveready battery‚ which is a regular‚ non-alkaline battery‚ lasted only 6 hours and 35 minutes. The Duracell lasted 15 hours. The Energizer lasted 22 hours and 15 minutes. The Rayovac lasted 24-1/2 hours. The Eveready flashlight went
