Explain what is meant by this phrase. This means that once the threshold is met‚ an action potential occurs. If the stimulus is too small an action potential does not occur. An action potential is usually initiated in an axon at or near what? The axon hillock‚ the initial segment‚ and the trigger zone. The adequate stimuli

Procedure and Analysis: The lab began with the group making a rough estimate of the force required from each arm to lift the weight up to be about 700N per arm. We then drew a force diagram for the force acting on the barbell and when the lifter held the barbell over his head. Were: B= the angle=35 degrees Fn= The normal force m= mass g=gravity F= the force exerted by each arm We then used the following equation W = mg to calculate the weight of the barbell. Were: W= weight

BIOLOGY 181 Lab # 4 Microscopy and Cells Lab A microscope is a tool that enables us to see objects and organisms that are invisible to the naked eye. Microscopes use a series of two or more lenses to magnify an illuminated image. Magnification is a measure of how big an object looks to your eye compared to “life size.” Microscopes also enhance the resolution of an image. Resolution is the ability to distinguish between two objects that are close together. Resolution can be increased using immersion

Effect of Temperature on Enzyme Activity Bernard Stepteau Biology Lab 101/Th 8:00am – 9:50am 2-26-2014 Dr Laynes Hypothesis: As the temperature of the enzyme catalase rises the activity of the reaction will decrease. Objectives: The objective is to compare catalase activity at different temperatures. Introduction Catalase speeds the breakdown of hydrogen peroxide. Catalase is present in every plant and animal organ. This is useful because hydrogen peroxide is harmful
