    offspring have the same genotype ratio as their parents. This example was one of Hardy-Weinberg equilibrium. The next generation will express the same genotype ratio as their parents, and so on. But what exactly is needed to create Hardy-Weinberg equilibrium? (Basically, a population in Hardy-Weinberg equilibrium s not evolving in any way.) Five specific factors are needed to create Hardy-Weinberg equilibrium within a population- a very large population, isolation from other populations, no net mutations

  • Justification by Reflective Equilibrium

    2717 Words  | 6 Pages

    Justification by Reflective Equilibrium Famously, John Rawls is regarded as using reflective equilibrium (RE) to justify his principles of justice. But the point of justification by RE in Rawls's more recent work is not easily established since he regards his own work as still contractarian. In order to clarify matters, I distinguish between wide and narrow RE, as well as show that wide RE consists of several kinds of narrow RE: RE as a plea for (re)consideration, RE as a constructive procedure

  • Freight Market Equilibrium Theory

    1326 Words  | 3 Pages

    Freight Market Equilibrium Theory An amazing assortment of goods are moved over the worlds ocean trade routes. Of necessity, the carriers charge for the service they render. These charges vary almost as widely as do the cargoes, for they mirror both the shipowner’s costs and the special conditions prevailing on the trade routes traversed by the ships. Ocean freight rates may be described as the prices charged for the services of water carriers. Each ship operator develops it’s own rates, usually

It does this in two ways; Passive Process - this does not require energy Active Process - this does require energy to occur This works in principle which

  • Consumer Equilibrium and the Law of Equi-Marginal Utility

    804 Words  | 2 Pages

    Consumer Equilibrium and the Law of Equi-Marginal Utility Introduction The Law of Equi-Marginal Utility is an extension to the law of diminishing marginal utility. The principle of equi-marginal utility explains the behavior of a consumer in distributing his limited income among various goods and services. This law states that how a consumer allocates his money income between various goods so as to obtain maximum satisfaction. Assumptions The principle of equi-marginal utility is based on the

  • Equilibrium Reaction Lab

    Chemistry IA: Equilibrium Reaction Lab Introduction: Reactions are based on collisions of particles, in which the particles must have sufficient energy. Some chemical reactions are reversible, and when the rate of the forward reaction equals the rate of the reverse reaction, the process has reached equilibrium. As it will appear to have stopped, as there is no overall change due to the rates being equal. Through this lab, we will be investigating one factor that will affect the equilibrium constant.

  • Equilibrium State Essay

    Objects in equilibrium state are defined as isolated objects with precise constant properties such as pressure, temperature and volume. In addition to that the total net force a nd acceleration must be equal to zero (1). Achieving equilibrium state requires knowledge in all object’s properties and behavior. The following research paper will carry the outcomes of our research in the topic, starting with a simple description of the types of the equilibrium state, followed by engineering and mathematical

  • Making Moral Decisions: The Synergistic-Reflective-Equilibrium Model

    4571 Words  | 10 Pages

    Making Moral Decisions: The Synergistic-Reflective-Equilibrium Model ABSTRACT: This treatise is a contribution towards the understanding of why humankind cannot agree on the foundation of morality and why moral pluralism is the logical constitution of moral reality. The synergistic-reflective-equilibrium model is the model that will describe how persons can make moral decisions as pluralistic agents. If this model is correct, then it will not be a new discovery, rather, it will be a new description

    Chemical Equilibrium October 14, 2017 Introduction This lab is centered around Le Chatelier’s Principle. In his research, he found that a chemical reaction can be manipulated to maximize yield. A change in one of the variables that describe a system at equilibrium produces a shift in the position of the equilibrium that counteracts the effect of this change. Le Chatelier's Principle describes what happens to a system when a stress is applied. Three ways in which we can change the conditions of a

    E4​​​​​​​​​​Professor Kiwiett A Study of Chemical Equilibrium ​The goal of the experiment was to determine the equilibrium constant of the equation between the reaction: [1] Assuming that SCN– was the limiting reactant, and that essentially all of it was used up to make FeSCN2+. In equation 1, it was known that the product, FeSCN2+ was the most intensified ion relating to light absorbance. By doing this, it was possible to equate the equilibrium concentration of iron (III) thiocyanate, [FeSCN2+]

    Gas Equilibriums: examples of Reversible Reactions Q1. Identify the general chemical and physical characteristics of gas equilibriums as a group. Explain the forward and reverse reaction mechanisms. Use nitrogen dioxide and hydrogen iodide as examples and explain how equilibrium is reached. The general chemical characteristic of gas equilibriums is when the concentrations of reactants and products do not change with time. This is known as the state of reversible reaction. At this state, pressure

  • The concept of Nash equilibrium is fine in theory, but next to useless in practice.

    562 Words  | 2 Pages

    Nash equilibrium by John Nash (1951) has been a central concept in game theories and further more for a wide range from economics even to the social and environmental sciences studies. Besides the game theory, David (2012) has recalled that, there are three unrealistic traits of standard economic model of human behavior – “unbounded rationality, unbounded willpower, and unbounded selfishness – all of which behavioral economics modifies.” However, consider the assumption of Nash equilibrium theory

    Factors Affecting the Equilibrium Reaction of Iron (III) and Thiocyanate ions Research Question How does the change in temperature of Iron (III) Thiocyanatoiron, containing iron (III) ions Fe3+ (aq) and thiocyanate ions SCN¬¬- (aq), affect the absorbance of the solution? - Temperature at 25 °C, 30 °C, 35 °C, 40 °C, 45 °C, 50 °C, 55 °C, and 60 °C (equilibrate the Iron (III) Thiocyanatoiron (aq) in various temperatures using a digital water bath, and temperature checked using a digital thermometer

  • Le Chatelier's Principle

    757 Words  | 2 Pages

    that if a change is made to a system in equilibrium, the system reacts in such a way as to tend to oppose the change, and a new equilibrium is formed. For example, whatever is done to the equilibrium, the system does the opposite. If something is added to a system at equilibrium, the system will behave as to remove it and vice versa. By increasing the concentration of a reaction, it will result in an increase of the rate of reaction. The new equilibrium will have a higher concentration of products

  • Island Biogeography Theory

    718 Words  | 2 Pages

    In the review article, “Equilibrium Theory of Island Biogeography and Ecology”, Simberloff (1974) described how the equilibrium hypothesis can be used to explain island biogeography. According to the author, islands offer significant scientific, economic, evolutionary, or ecologic importances due to their unique characteristics (isolation, insular depauperization). However, detailed study on the somewhat puzzling island biogeography is limited. Therefore, Simberloff (1974) provided an in-depth research

    Landforms and Processes All rivers aim to reach equilibrium so they are balanced and when they are in equilibrium from source to mouth a smooth curve is created called the graded long profile. However, as you can see from the diagram many rivers such as The Afon Glaslyn, do not acheive equilibrium and reach their graded long profile: Long Profile of Afon Glaslyn River with graded long profile [IMAGE][IMAGE] Rivers become out of equilibrium when there is a change in base (sea) level. There

    be broken down into smaller controlling factors. The global energy balance is an equal balance of short-wave radiation coming into the atmosphere and long-wave radiation going out of the atmosphere. This is called thermal equilibrium. The earth is at thermal equilibrium; however, there can have a surplus or deficit of energy in parts of the heat budget. If you have a net radiation surplus warm air will rise, and a net radiation deficit will make the air cool an fall. Air gets heated at the
