In other words‚ the customer simply sees a product and purchases it. Using suitable arguments and examples‚ explain why consumers buy impulsively. Impulse buying behavior Impulse buying is a buying behaviour characterized as unplanned‚ spontaneous‚ immediate‚ unconscious and emotionally driven. Unplanned purchase that is characterized

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. We used the sciatic Lithobates pipiens nerve in this experiment‚ the sciatic nerve is long nerve‚ it extends from the buttocks

Chapter 8 Summary In Neil Postman’s book‚ Amusing Ourselves to Death‚ he attempts to persuade Americans that television is changing every aspect of our culture and world. In chapter 8‚ Shuffle Off to Bethlehem‚ Postman uses three arguing styles very well: ethos‚ pathos‚ and logos‚ which help him push the reader‚ specifically televised religion viewers and churchgoers‚ to believe that televised religion is not a replacement for religion. Throughout the chapter‚ Postman creates the feeling of guilt

Introduction A nerve is an enclosed bundle of axons found in the peripheral nervous system (Easton 13). It is the pathway for electrochemical nerve impulses‚ which pass along axons of the peripheral organs. A neuron is a cell in the nervous system which plays many critical tasks like receiving sensory signals from the external and internal environments. Moreover‚ neurons join together these sensory responses to produce and transmit motor responses as a result of changes in membrane permeability

CHAPTER 8 How Did They Make And Use Tools? Technology Summary The physical remains of humanly made artifacts form the bulk of the archaeological record. The artifacts that are found by archaeologists may not represent the range of objects actually used because certain materials preserve better than others. For this reason‚ stone tools and ceramics dominate the archaeological record. Objects made of fabric‚ cord‚ skin‚ and other organic materials no doubt date back to the very earliest archaeological

use of Nerve agents‚ and to a larger extent Chemical Weapons‚ is illegal according to United Nations Resolution 687 which passed in 1991. The production‚ stockpiling‚ and use of these weapons were banned by The Hague Convention of 1899 and the Geneva Protocol of 1925. All Nerve agents are fatal to the human body in the same way. Some are more potent‚ and some remain on the battlefield longer than others. Many factors play a role in how long a Nerve agent remains on the battlefield. Nerve agents come

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer
