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

John Heger CMY 211 Lab Section 13 11-30-2011 Borohydride Reduction of Vanillin to Vanillyl Alcohol Introduction: The purpose of this lab was to reduce vanillin to vanillyl alcohol. This lab report recaps the procedure and results of the lab. The chemical process studied in this lab was reduction‚ the process of reducing the number of bonds to oxygen and increasing the number of bonds to hydrogen. Other chemical processes included in the lab were recrystallization‚ melting point‚ and extraction

Locomotor activity The Locomotor activity (Pákáski and Kálmán‚ 2008) refers to the movement of spontaneous locomotor and exploratory activity in rodents. LMA is a simple performed measurement of behavior to detect the effects of drugs‚ genetic manipulation‚ etc.‚ on motor function by measuring horizontal‚ vertical and stereotyped behavior in rodents. Several measures of locomotor activity in rats‚ including the distance covered‚ movement time and speed of progression. This test is sensitive to

WHAT IS HARM REDUCTION? Harm reduction is a set of practical strategies intended to reduce the negative consequences of high risk behavior such as over drinking or drug abuse. Harm reduction is a non judgmental approach that attempts to meet people where they are at with their drinking or drug abuse. Instead of demanding perfect abstinence‚ this pragmatic approach is supportive of anyone who wishes to minimize the harm associated with a high risk behavior such as drinking or drug abuse. Harm

The Pros and Cons of a Breast Reduction Shavanna Levette Hudson Instructor: Pamela Jongbloed ENG 121 English Composition I July 29‚ 2014 The Pros and Cons of a Breast Reduction The decision to have a breast reduction surgery came after years of continuous back pain throughout my life. My experience has been a real journey in researching the right doctor and asking the right questions for this type of surgery. My journey began in 2012 after many attempts to lose weight. I began doing

experiment of making borneol from camphor (FIGURE-3) is performed in two different methods‚ Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction‚ to compare the relative product ratio of borneol to isoborneol. The concept of reduction and also oxidation‚ the opposite procedure of reduction‚ deals mostly with electron transfer between atoms. It will not be elaborated here‚ but the reduction procedure involved in this experiment is basically adding hydrogens and losing the carbon-oxygen double

Preparation of food takes a lot of time. Even if the dish is only composed of fruits. A lot of dishes have vegetables in them. These can also be useful especially when preparing lots of different food at the same time. If you look at cooking websites they will suggest to use lemon water. In our experiment we will attempt to find out which is better at preserving the sliced‚ chopped‚ and or diced food. Since our experiments are limited by time and costs‚ we will stick to the simplest of the available
