Individual Exercise 3 (10 points) 1. A shoe manufacturer’s data show that the distribution of shoe size is normal with a mean of 11inches and SD 1.5 inches. * A manger of the company claims that 70% of the times shoe size will be between 8 and 12 inches. What do you think? In your deliverables‚ write a few lines about what you think of the manager’s claim and what would you advise him to do. (1 point) * How would you modify the manager’s claim if the distribution of shoe size was not

Introduction and Objective The action potential is an impulse of electrical activity. Action potential occurs when a neuron sends messages electrochemically down an axon called a nerve impulse. When a neuron is not stimulated or inactive‚ it is at resting potential. When a neuron is at rest‚ the electrical charge on the inside of the neuron is negative while the electrical charge on the outside of the neuron is positive. The resting membrane potential of a neuron is about -70 mV (mV = millivolts)

Activity 1 1. Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. Therefore‚ the K+ ions will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. 2. Increasing extracellular K+ causes the membrane potential to change to a less negative value because the K+ ions diffuse out across the membrane. My results went well compared to my prediction

The purpose of this experiment was to observe the process of diffusion of substances across a semipermeable membrane to gain a better understanding of how cells move materials across cell membranes. The experiment was designed to exhibit Brownian Motion; the random movement and tendency of particles of a substance to move from an area of greater concentration to lower concentration via diffusion until equilibrium has been attained. In addition to observing the passive process of diffusion‚ the experiment

Ad Hominem; This is under Ad Hominem because the arguer is supporting her claim by pulling information from the her personal life instead of using the knowledge they know about the subject being a leader. 2. A child can be either an athlete or a good student. a. Either-or; this is under the Either-or category because the argument comes

Activity 1 1. Describe two variables that affect the rate of diffusion. a. There are alot of different variables or factors that can affect the rate of diffusion‚ for example: size of the molecule‚ shape of the molecule‚ concentration gradient‚ charge of the ions‚ temperature‚ environment‚ etc. The rate of the diffusion can increase as diffusion distance increases‚ concentration gradient increases‚ surface area increases‚ temperature increases‚ and many more. 2. Why do you think the urea was not

find the effect of temperature on the membrane permeability of beetroot. Since I was unfamiliar with this experiment‚ I first conducted a preliminary test. I considered my preliminary test as my trial for this experiment. My Hypothesis for this experiment was to found out the amount of pigment loss of beetroot when exposed to varying temperatures. Betalain pigment found in beetroot My method for this experiment is:- * Use a cork borer to cut about 3 cores of fresh beetroot approximately 8mm in length
