A passive process‚ diffusion / osmosis is the movement of solute molecules from an area of greater concentration to an area of lesser concentration. 2. A solution surrounding a cell is hypertonic if: a. it contains fewer nonpenetrating solute particles than the interior of the cell. b. it contains

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)

Describe two variables that affect the rate of diffusion. Size of material and concentration 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? The molecules were too large to pass through. This is what I predicted

Methodology The researchers used purposive sampling technique wherein‚ there were 61 respondents. They used survey questionnaire as the data gathering instrument. The researchers used frequency and percentage‚ ranking scale‚ weighted mean and the Pearson Correlation Analysis to know if there was significant relationship between the demographic profile (age and gender) of the respondents and their perception on the outdoor advertisements of Tanay‚ Rizal. Findings There was a total number of 61

Critical Analysis of Plato’s Apology 40c-42a Plato’s Apology is one of the most well-known pieces of Plato’s writing today‚ perhaps due to a certain dramatic style and context that can appeal to any reader. The ‘Apology’ is the defence speech of Socrates before the court at a trial for his life. He has been accused of deliberately corrupting the young and of non-belief in the Athenians’ gods. It is widely accepted that this is a true event‚ Socrates was tried‚ found guilty and put to death. What

Introduction: In this lab‚ I will study how muscles contract‚ what makes muscles contract‚ different types of muscle contraction‚ and learn about how resistance affects muscle contraction. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Recruitment (or Multiple
