Abiotic factors which include climate are known to affect plant growth. Elevation which influences the climatic conditions can directly affect the tree height. The trees in higher elevation are thought to be shorter than trees in lower elevation because of the low temperatures which directly affects the height of trees. The experiment was done to ascertain tree height difference and to fulfil the deadline. The hypothesis for the experiment was that trees in lower elevation grow taller than trees at a higher elevation. The methodology for the experiment included measuring tree height in high and low elevations. Tree height ...

Abstract

The ecological settings in an ecosystem change from time to time. The changes in the ecological settings are brought about by a plethora of factors. Through evolution, the organisms that live in the ecosystem also change to adapt to the aforementioned ecological changes. The adaptation of the organisms to the ecological changes yields variations because different organisms and even organisms of the same species are exposed to the elements to different levels. Man has a significant role to play in the ecological changes. Through his economic activities, the effect on ecosystems has been both positive and negative. Urbanization as ...

Introduction

The book The Lucifer Effect by Philip Zimbardo argues that beneath any man lies some degree of evil, so detrimental if exposed under duress. The Lucifer Effect explains how good men can transform when exposed to stressful environments to commit heinous activities beyond imaginable moral magnitudes. In this regard, the author empirically explains the findings of the Stanford Prison Experiment (SPE) the processes involved in transforming good men into committing evil and heinous activities under duress and powerful situational forces. A comparison between the SPE findings and those of the Abu Ghraib prison in Iraq have strong correlations in ...

The character I chose for a reflective journal is John B. Watson. He is a representative of behaviorism and one of the most important persons in American psychology. It is essential to note that his views prevailed in American psychology for 50 years, and nowadays his ideas in altered form are still important. However, I am impressed by his points of view, behavioral, and radical experiments with a child. John B. Watson launched the behaviorist movement, rejected the philosophy of the past, the method of introspection, and mentioned that mental events were beyond the pale of scientific psychology. Unfortunately, ...

Summary Of Proposed Research

Global drought not only affects the world agriculture and economics, but interactively affects the phenotypic trait of plants across a different diversity gradient. Nevertheless, plants are able to adapt themselves to the drought environment by changing their phenotypic trait. From previous research at Jena Drought Experiment, in Germany, the results show that diversity not only has the capability to increase community’s resistance to drought, but also to increase community’s recovery ability after drought. On the other hand, the results show that the drought environment makes a strong selection on both, the plant phylogeny and functional trait. Yet, ...

Potentiometric titration is a volumetric method which measures the potential between two electrodes, namely reference and indicator, with the change in the volume of the reagent that is added, known as the titrant. ...

Why aren't detectives more successful at solving crimes? Given their relative lack of success, how do you account for the "detective mystique"? In this essay, share some solutions to make solving crimes more effective. One of the major reasons why some detectives have difficulties in solving crime is because they lack the necessary skill, particularly the intellectual capacity to perform their job. One of the major challenges of law enforcement agents in solving crimes is the cleverness and cunning of criminals. Although there are many theories and procedures that aims to aid detectives in solving crimes, the successful ...

Abstract

The most crucial goal that has been targeted in all research studies in the past few years has been toward prevention of problems. The scientific method is a stringent and proven procedure, which can be used to determine the most probable evidence to back up an environmental phenomenon. The proposition is usually made in a cause-and-effect phenomenon. Such a proposition is known as a ‘hypothesis’. The method used for testing the hypothesis is termed ‘experimentation’. This procedure is comprised of five elementary and significant steps. The most salient aspect that renders the scientific methods most popular is the fact ...

An acid is a solution that loses hydrogen ions. Common household acids include vinegar and citrus fruit juice. In contrast, a base is a solution that gains hydrogen ions. Acidic substances often taste sour whereas bases taste bitter and feel slippery. Since the tasting or touching of acids and bases can be harmful to human health, Occupational Safety and Health Administration (OSHA, 2013) recommends the use of indicators to test for the acidity or alkalinity of substances. Typically, indicators such as litmus paper change color when exposed to acids or bases (Stanley et al., 2015). As such, the present ...

Part 1: Answers to Preliminary Questions

• Photosynthesis is the process by which green plants use sunlight energy to manufacture food using water and carbon dioxide as raw materials.

• An increase in the intensity of sunlight increases the rate of photosynthesis up to a given level.

• Photosynthesis and respiration processes complement each other. It is possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions. This can be conducted by setting up an experiment with two sets of experimental set-ups. In each set-up, there should be two test-tubes: one with a high concentration of carbon dioxide and another with a high concentration of oxygen. One pair of test tubes, consisting of a test-tube with a high concentration of oxygen, ...

Validity in Research Design

Validity in Quantitative Research Designs Validity refers to the degree to which physical evidence supports an experimental concept or conclusion. In statistics, it refers to the level of confidence that researchers hold on a particular causal effect of an experiment. The most common challenges to internal validity in the research design occur from the selection process of target population as well as the sample size (Yuan et al., 2009).In particular, the selection process in the article reflects only persons who have volunteered for the research. Ideally, this represents a threat to internal validity since the individuals used in ...

Differences between a causal and a correlation Causation refers to the cause of something to happen. A causal claim shows that the two events are related to each other in such a way that one event is the effect of the other. Suppose there are two events; b and c, then a causal claim can take the form of “b causes c” in which b refers to the cause and c refers to the effect. On the other hand, correlation shows that the two variables (events) are related to each other in such a way that ...

Introduction

The “Scientific Method” characterizes science from other fields of studies. It encompasses methodologies of scientific inquiry that follow certain patterns to easily obtain and make experimentation easier. The scientific method is improved as science and technology progress but it has the following general parts that are universal: a. identifying the problem statement, b. formulation of hypotheses, c. observation from sampling, measurement and description of the data obtained, d. formulation of inductions, e., employing theories and finally, f. formation of conclusion (Oxford University Press). These steps are greatly relevant to obtain the desired data for an experiment and with the ...

Introduction

The Scientific method is a framework followed by scientist in investigating a certain inquiry or process. Scientific method is a series of steps that was established during 1619 by Rene Descartes. This then led to the improvement of the principle so as being used until the recent times as a principle that guides every scientific fields (McLelland, n.d.). With scientific method, biases from personal prerogatives and the influence of environmental and social concerns are eradicated. The scientific method employs the utilization of testing procedures to verify claims that can be reproduced to strengthen the credibility. Scientific method is a ...

Introduction

Water is termed the ‘universal solvent’ since it is capable of dissolving a large variety of substances. These solutes can be broadly classified as ionic and molecular solutes, based on their behaviour in solution. Ionic solutes dissociate into their constituent ions when dissolved in water. An example of this class is sodium chloride (common salt). Molecular solutes are dissolved as uncharged molecules, like sucrose (sugar). The effect of ionic solutes on the boiling point of water is the focus of this project. Boiling occurs when the vapour pressure above a liquid equals the pressure over it. Hence, the normal ...

Introduction: All most all metals are unstable when exposed to air. This is because of the tendency of the metal to be converted into its oxidized form on reaction with air. When compared to zinc, iron has a greater tendency to form oxidized form and thus has greater susceptibility to corrosion. The ability of metals to react with air varies and this determines their relative stability. As zinc is much stable when compared to iron, it is used to galvanizing iron pipe, thus preventing contact of iron with air and water that contains dissolved air. Brass is an alloy ...

Question one

The concept addressed by ‘Anatomy of Prejudices’ is diversity and asserts that different individuals have varied perceptions and attitudes on others. Diversity generates the need to address issues of racism in an organization and how their views on others shape behavior, attitudes, and values of individuals. The ‘Anatomy of Prejudices’ draws useful insights on how racism drives individuals to have negative stereotypes that prevent them from actively engaging in interactive sessions with the minority. The video reflects the fact that the majority are among those who lead in racism and have ill motives to suppress minority’s influence in ...

Introduction

Learning a foreign language is a slow and progressive effort which requires constant and responsible practice. Independent study is absolutely necessary for progress, and the hours spent in the classroom are not nearly enough in order to achieve fluency. This is particularly true for languages which are considered difficult to master, such as Mandarin. In recent years, Mandarin has become one of the most important foreign languages studied in schools throughout the United States of America. Mastering Mandarin challenges students to a great extent, even though many of them choose to study this language. Consequently, many teachers use the ...

While Beck argues that depression results from negative thinking styles that results to how people view their environment, Psychologists Martin Seligman and his colleagues postulated the concept of Learned Helplessness. The main key to how the group discovered this theory is by researching on the linkage between fear and learning in dogs. The research of Seligman made use of Classical Conditioning as it involved observing what happens when a dogs was set free from its enclosure upon hearing a sound. The remarkable results of the experiment suggest that the conditioned dog learned more than link between the tone and ...

What does the margin of error tell us about a sample taken from a large population? How does the confidence level for a sample outcome differ from the sample’s margin of error? The margin of error is a numerical value that expresses or estimates the likelihood of error in an experiment’s results. Thus, it can somehow account for the statistical significance of a result. If it is smaller, then the likelihood of error is also small, making the results more credible. Smaller sample sizes from a large population generally have a larger margin of error while larger ...

Introduction

The relation between the potential difference, electric current, and resistance are represented in the Ohm Law. The Ohm Law consists in the direct relation between the potential difference and the electric current of a basic circuit, where the resistance is the constant value in the relation. Mathematically speaking the Ohm Law is a first-grade equation where the potential difference is the dependent variable, the electric current the independent variable and the resistance a constant value. With a deep analysis of the circuit, the resistances are components inside the circuit that difficult the path of the electric current through the ...

What is the relationship between the predicted outcome and the claim being tested in scientific experiment? An experimented outcome can be compromised in two ways. What are they and how do they differ? The predicted outcome is a common aspect of science with a particular interest in scientific research studies. In science, questions about truth and the claims of certain phenomena are answered through empirical evidence. Nevertheless, there are instances where scientists make educated guesses on a particular test subject. A predicted outcome can be proved right based on measurable evidence in a hypothesis experiment. On the other hand, ...

The Rosenhan experiment used in the establishing the validity of psychiatric diagnosis conducted in 1972 by David Rosenhan, titled “On being sane in insane places” consisted of two main parts. The area second part of the experiment, where the staff in the psychiatric hospitals falsely detected a large number of genuine patients as impostors is not a justification as to why the sane people cannot be distinguished from the insane in psychiatric hospitals (Fontaine 348-365). It is this is because in the experiment, the inability of the nurses to identify the imposters cannot be a generalized aspect, their inability ...

Introduction

XX century was characterized with the significant technological progress, which has improved the life of people. Numerous products and services became available, labor and domestic life became easier and more comfortable. However, waste problem is the other side of the technological progress. The solid, liquid and gas waste are formed, and thus land, natural water and air quality degrade. Therefore, in XXI century the research efforts are dedicated to development of methods for sustainable use of water, gas, and solid resources. Wastewater polluted with dye residuals originate from textile, leather and food industry. These industries produce goods that ...

Electrophilic Aromatic Substitution to yield 4-Bromoacetanilide

Introduction Halogenation is a common process in organic synthesis. It is used in industrial and research synthesis as halogenated compounds are used for numerous widely used goods, including plastics. The lab aimed to perform monohalogenation of acetanilide. The reaction is specific since it is performed without catalyst. The typical halogenation is realized in presence of Lewis acid. Halogens molecules are electrophilic, and do not actively react. In presence of Lewis acid, the interaction is rather active.2 The lab used catalyst-free halogenation. The acetanilide molecule contains the acylated amine. As a result, the electronic density is shifted towards the amine ...

Abstract

The impact of salt on melting of ice can be described as utilizing atomic progression recreations. The harmony the point of solidification melancholy saw in the recreations is in great concurrence with trial information. The dynamic parts of liquefying are examined as far as the trading of water atoms amongst ice and the fluid stage (Brique, 1967). The ice/fluid harmony is a profoundly dynamic procedure with the incessant trade of water particles amongst ice and the fluid stage. The parity is irritated when ice dissolves and the softening continues in two phases; the restraint of the relationship of water ...

When power is granted to an individual to exert over another, interesting things can happen. The balance of authority is often tenuous and can be navigated if the semblance of order is respected and followed. When that order is ignored and the authority is placed in the hands of those who seek to use it for personal gain however, the balance is quickly lost. The Stanford Prison Experiment shows how absolute power corrupts absolutely. Seeking to display the very real situations that occur between prison guards and convicts, a study was conducted at Stanford University in 1971 to test ...
