Fuel cells

the case of humanity, not only does a generation leave behind its culture, but also the state of the Earth. Over the past 50 years, there has been a significant increase in the consumption of natural resources. In addition to the depletion of fossil fuels and natural gas, this increased consumption is damaging the planet; the increased carbon dioxide levels has caused the destruction of the ozone layer, and its level of protection to the surface of Earth. More of the sun’s dangerous rays reach…

are made up by the building blocks of life named “cells”. They are the foundation of life and contain microscopic components called organelles which carry out complex tasks to provide the “basic structural, functional, and biological unit of all known living organisms” (Wikipedia, Cell(Biology), viewed 19th March 2016, Cells can be classified into two major groups- Prokaryotic and Eukaryotic cells. Prokaryotes are organisms that do not contain a cell nucleus and have no membrane bound…

The Cell Membrane is one of the most important parts of the cell. If not for the cell membrane it would be extremely easy for things to invade the cell; this is because on of the cell membranes job is to control what come in and out of the cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in…

The mitochondria is one of the most interesting components of the eukaryotic cell. Endosymbiosis is the term modern scientists use for how the mitochondria came to be. Symbiosis translates from Greek to English as “living” “together.” Constrantin Mereschkowsky, known as the founding father of the theory of endosymbiosis, was one of people who started the concept of endosymbiosis, although he had called it “symbiogenesis,” defining it as: “the origin of organisms through the combination and…

Protein are the central to life because they control almost all cellular processes, including initiating most of the reactions that occur in the living thing cells. They are one of the building blocks of body tissue and also can serve as fuel source. They are naturally occurs which means that they are made by living cells, like animals, bug, fungi and even human. They can interact with one another and other biological macro mules to form complex assemblies. Some are quite rigid whereas others…

There are two types of gene therapy treatment: Somatic cell gene therapy and germline therapy. Somatic cell gene therapy includes gaining blood cells from a person with a genetic disease and then inject a normal gene into the defective cell. This type of gene therapy cannot be passed down generations (from parent to child) because it does not affect the egg and sperm cells. Somatic cell gene therapy needs to be done a few times to be permanent in a patient. The other…

Macromolecules are of great interest to the study of anatomy and physiology due to the fact that they carry out most functions of a cell providing it with life. They provides structural support, a source of stored fuel, the ability to store and retrieve genetic information, and ability to speed biochemical reactions (Prakash, 2008). There are four main types of macromolecules including proteins, carbohydrates, nucleic acid and lipids. This essay is specifically on the study of carboyhdrates as…

Below, one representative graph and a set of sample calculations are included which will show how the values for the enthalpy of combustion of the fuel sources are deduced. Graph 1: Scatter plot showing the change in the temperature of 80.0mL of distilled water in the tin calorimeter during and after the combustion of the kerosene for the first conducted trial. The linear trendline was created for the last three data points, where the water was allowed to cool, which was then extrapolated…

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…
