"Adversity has the effect of eliciting talents in prosperous circumstances would have lain dormant." What Horus described in this quote‚ meant that when hardships or impossible tasks face a person‚ and if that person has the courage and will to achieve them‚ the man will uncloak his true strengths. No one could disagree with this‚ including me. Believing in our own skills and believing that anything can be achievable‚ creates a way for us to prove others wrong and prove yourself right. Millions

The Nervous System: Ion Channels 1. What structures in the cell membrane function as ion channels? Intergral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? a. Charge on ion (+ or -) b.Size c. The amount of water the Ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an non-gated channel. 4. Would
Premium Neuron Action potential Nervous system
neuron carries important information through action potential‚ this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons

Anesthetic ether is the actually diethyl ether CH3CH2OCH2CH3. It has been used as an anesthetic in medical surgery for over 150 years‚ though the hypnotic effects of ether was already discovered 500 years ago. The historical development of ether anesthesia is very dramatic and interesting. Ether anesthesia: The historical development Ether was discovered in 1275 by Spanish chemist Raymundus Lullius‚ and was named ¡§sweet vitriol." In 1540‚ a German scientist Valerius Cordus described the synthesis

simplest way to synthesize an ether is to have an alkoxide react with a primary haloalkane or a sulfonate ester under typical SN2 conditions. The scientist who developed this reaction‚ Alexander W. Williamson‚ was a professor at University College in London in the latter part of the 1800’s. This reaction has been around a while! Secondary haloalkanes and sulfonate esters are occasionally used in the Williamson ether synthesis but the yields are often poor. The ether prepared in this experiment is

The Action Potential An action potential‚ also called a spike‚ nerve impulse‚ and discharge‚ is the rapid reversal of charge of the cell membrane. These changes in charge occur within milliseconds‚ meaning the action potential travels very quickly down the axon in order to convey information over long distances. This transfer of information occurs within six phases and requires the presence of multiple pumps and channels embedded in the membrane to control ion concentration. Phase 1: The Resting

n 8 POTENTIAL FINGERNAIL HEALTH WARNINGS INTRODUCTION: Fingernails and disease don’t go together in most minds… but they should. Your fingernails can give you valuable health warnings and signal the presence of serious disease. Take a good look at your nails. Hold a hand level with your nose about a foot out from your face and scrutinize each one. Look at the curves‚ dips‚ ridges‚ and grooves. Check out how thick or how thin they are and if your nails are chipped or broken. Make a note of

POTENTIAL EFFECTS OF DISCRIMINATION. TASK 3: In looking at this task‚ we have already studied the first part of the topic at the beginning of the Unit. Forms of Discriminatory Practice exist‚ in the form of: Prejudice‚ Stereotyping‚ Labelling‚ Bullying‚ Abuse‚ Lack of choice‚ Infringement of Rights‚ and Covert/Overt abuse of Power. Do we accept that these forms of discrimination exist? What do you think……as maybe you do not agree? Discrimination can be understood as damaging the individual

Task 3 P3 - The potential effects of discrimination There are lots of potential effects related to discrimination. It includes things like disempowerment‚ low self-esteem and self-identity and also marginalisation. I am now going to explain these effects and connect them with a case study. Disempowerment is when a person or group of people may be made to feel less powerful or confident. Some people may try to fight against the discrimination causing an argument but many people do not and they lose
