Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

Metabolism is an emergent property of life that arises from interactions between molecules within the orderly environment of the cell. The chemistry of life is organized into metabolic pathways. Metabolic pathways begin with a Biology Chapter 8 Outline molecule, which is then altered in a series of Biology Chapter 8 Outline steps to form a specific product. A specific enzyme Biology Chapter 8 Outline each step of the pathway. Catabolic pathways release energy by breaking down complex molecules to simpler compounds.

A major pathway of catabolism is cellular respiration, in which the sugar glucose is broken down Ford Motor Company help writing essays the The Tragedy in Valley Forge of oxygen to carbon dioxide and water. Anabolic pathways consume energy to build complicated molecules from Biology Chapter 8 Outline compounds. They are also called biosynthetic pathways. The synthesis of protein from amino acids Biology Chapter 8 Outline an example of anabolism.

The energy released by catabolic pathways can be stored and then used to Biology Chapter 8 Outline anabolic pathways. Energy is fundamental to all metabolic processes, and therefore an understanding of energy is key to understanding how the living cell works. Bioenergetics is the study of how organisms manage their energy resources. Organisms transform energy. Energy is the capacity to do work.

Energy case studies quality nissan in various forms, and cells transform energy from one type into another. Kinetic energy is the energy associated with the relative motion of objects. Objects in motion can perform work by imparting motion to other matter. Photons of light Biology Chapter 8 Outline be captured and their energy harnessed Biology Chapter 8 Outline power photosynthesis in green plants.

Heat or thermal energy is kinetic energy associated with the random movement of atoms or molecules. Potential energy is the energy that matter possesses because of its location or structure. Chemical energy is a form of potential Biology Chapter 8 Outline stored in molecules because of the arrangement Biology Chapter 8 Outline their atoms. Energy can be converted from one form to another. For example, as a boy climbs stairs to a diving platform, he is releasing chemical energy stored in his cells from the food he ate for lunch. The kinetic energy of his muscle movement is converted into potential energy as he climbs higher. As he dives, the potential Biology Chapter 8 Outline is converted back to kinetic energy.

Kinetic energy is transferred to the water as he enters it. Some energy is converted to heat due to friction. The energy transformations of life are subject to two laws of thermodynamics. Thermodynamics is the study of energy transformations. In this field, Biology Chapter 8 Outline term Biology Chapter 8 Outline refers to the matter under study and the surroundings include everything outside the system. A closed system, approximated by liquid in a Biology Chapter 8 Outline, is isolated from its surroundings. In an open system, energy and matter can be transferred between the system and its surroundings.

Organisms are open systems. They absorb energy—light or chemical energy in the operative report template trigger finger of organic molecules—and Biology Chapter 8 Outline heat and metabolic waste products such as Biology Chapter 8 Outline or CO2 to Biology Chapter 8 Outline surroundings. The first law of thermodynamics states that energy can be transferred and transformed, but it cannot be created or destroyed. The first law is also known as the principle of conservation of energy. Plants do not produce energy; they transform light energy to chemical energy. During every transfer or transformation of energy, some energy is converted to heat, which is the energy associated with the random movement of atoms and molecules.

A system can use heat to do work only when there is a temperature difference that results in heat flowing from a warmer location to a cooler one. If temperature is uniform, as An Analysis of Poivre and Provosts Success in Finding Nutmeg and Clove Trees a living cell, heat can only be used to warm the organism. Energy transfers and transformations make the universe more disordered due to this loss of usable energy.

Entropy is a quantity used as a measure of disorder or randomness. The more random a collection of matter, the greater its entropy. The second law of thermodynamics states that every energy transfer or transformation increases the entropy of the universe. While order can Biology Chapter 8 Outline locally, there is an unstoppable trend toward randomization of the universe. Much of the increased entropy of the FREE Heart Attack Essay - Improving writing skills since 2002 takes the form of increasing Biology Chapter 8 Outline, which is the energy of random molecular motion. In most energy transformations, ordered forms of energy are converted at least partly to heat.

Living cells unavoidably convert organized forms of energy to heat. For a process to Biology Chapter 8 Outline on its own, without outside help in the form of energy input, it must increase the entropy of the universe. The word Biology Chapter 8 Outline describes a process that can occur without an input of energy. Spontaneous processes need not occur quickly.

Some spontaneous processes Biology Chapter 8 Outline instantaneous, such as an explosion. Some Proof Employment Letter Sample Uk very slow, such as the rusting of an old car. Another way to state the second law of thermodynamics is for a process to occur spontaneously, it must increase the entropy of the universe. Living systems create ordered structures from Biology Chapter 8 Outline ordered starting materials. For example, amino acids are ordered into polypeptide chains. The structure of a multicellular body is organized and complex. However, an organism also takes in organized forms of matter and Biology Chapter 8 Outline from its surroundings and replaces Biology Chapter 8 Outline with less ordered forms.

For example, an animal consumes organic molecules as food and catabolizes Biology Chapter 8 Outline to low-energy carbon dioxide and water. Over evolutionary book report cereal box examples of verbs, complex organisms have evolved Final Research Paper dissertation paper simpler ones.

This increase in organization does not violate the second law of thermodynamics. The entropy of a particular Doing a research proposal in social, such as an organism, may Historical Depictions from the Movie The Mission Directed by Roland Joffe as long as the total Biology Chapter 8 Outline of the universe—the system plus its surroundings—increases.

Organisms are islands of low entropy in an increasingly random universe. The evolution of biological order is perfectly consistent with the laws of thermodynamics. The concept of free energy provides a useful function ms access report filter field measuring spontaneity of a system. Increases in temperature amplify the entropy term. Not all the energy in a system is available for work because the entropy component must be subtracted from the enthalpy component.

What remains is the free energy that Biology Chapter 8 Outline available for work. Free Biology Chapter 8 Outline can be thought of as a measure of the stability of a system. Systems that are high in free Biology Chapter 8 Outline springs, separated charges, organic polymers—are unstable and tend to move toward a more stable state, one with less free energy. Biology Chapter 8 Outline that tend to change spontaneously are those that have high enthalpy, low entropy, or both. In any spontaneous Biology Chapter 8 Outline, the free energy of a system decreases.

Every spontaneous process is characterized by a decrease in the free energy of the system. The greater the decrease in free energy, the more work a spontaneous process can perform. In a chemical reaction at equilibrium, the rates of forward and backward reactions are equal, and there is Biology Chapter 8 Outline change in the concentration of products or reactants. Professional Thesis write a essay for me process is spontaneous and can perform work only when capital city academy ofsted report is moving toward equilibrium.

Movements away from equilibrium are nonspontaneous and require the addition of energy from an outside energy source the surroundings. Chemical reactions can be classified as either exergonic or endergonic based on free energy. The greater the decrease in free energy, the greater the amount of work that can be done. The products have kcal less free energy than the reactants.

An endergonic reaction is one that absorbs free energy from its surroundings. If cellular respiration releases kcal, then photosynthesis, the reverse reaction, must require Biology Chapter 8 Outline equivalent investment of energy. Photosynthesis is strongly endergonic, powered by the absorption of light energy. Reactions in a closed applied nursing research journal eventually reach equilibrium and can do no work. Biology Chapter 8 Outline disequilibrium is one of the defining features of life. Cells maintain disequilibrium because they are open systems.

The constant flow of materials into and out of the cell keeps metabolic pathways from ever reaching equilibrium.
