Natural Gas Diesel Fuel
733 wordsWe have known for a long time that eventually our oil deposits will dry up, and it would be helpful at that time if we had some kind of alternative fuel to power all of the machines that we use. Over the past two decades more oil has been pumped than has been found in the world. For this reason scientists have been looking to potential alternative fuels for the future. One of these alternative fuels may come in the form of natural gas. Natural gas has been found to be more plentiful than oil, an...

Oxygen And Carbon Dioxide Oxygen And Carbon Blood
374 wordsRespiratory gases-oxygen and carbon dioxide moves between air and blood in the lungs. The structure of the human lung provides immense internal surface that facilitates gas exchange between the alveoli and the blood in the pulmonary capillaries. Respiratory gases move between the environment and the respiring tissues by two principal mechanisms, convention and diffusion. Convention is responsible for movement of air from the environment into the lungs and also for the movement of the blood betwe...

Sexually Transmitted Diseases Mucous Membranes
1,169 wordsS. T. D. , what does it mean? It stands for Sexually Transmitted Disease. STDs used to be called venereal diseases. Sexually transmitted diseases have been around for a long time. There were references to gonorrhea in the Old Testament and descriptions of syphilis at the time of Columbus. Sexually transmitted diseases cross all boundaries. They are not restricted to people of one sexual orientation, race, cultural group or socioeconomic class. When most people think about infectious diseases, th...

Photosynthesis Changing Carbon Dioxide And Water To Sugars
643 words6 H 2 O + 6 CO 2 gt; C 6 H 12 O 6 + 6 O 2 Six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen Photosynthesis is the process that green plants and certain other organisms use to change carbon dioxide and water into glucose (sugar) using the suns energy. Photosynthesis provides the basic energy source for practically all living organisms. A very important byproduct of photosynthesis is oxygen, which we cant live without. Photosynth...

Desalination Plants Sea Water
1,236 wordsPurification of Sea Water In the late 20 th century, more than 8, 000, 000 cubic m (2, 112, 000, 000 gallons) of fresh water were produced each day by several thousand desalination plants throughout the world. Distillation processes are used in about half of all the plants and account for roughly three-quarters of the worlds desalted water. Most of the other plants employ membrane processes. The worlds desalination capacity expanded rapidly during the 1970 s and 80 s as the oil-rich countries of...

Begin To Feel Carbon Monoxide
1,141 wordsCarbon Monoxide Poisoning Imagine that it is the first really cold night of the winter season. You begin to feel a chill in the house so you decide its time to turn on the furnace. So you get up out of your chair and adjust the thermometer. After a while you notice that it has not really warmed up much in the house. So you decide to check it again just as soon as you get something for this awful headache that just came on. But, as you get up out of your chair you almost fall over because you are...

Amino Acids Fatty Acids
807 wordsToday, weve realised that the very first life on Earth was indeed originated from abiotic surroundings. In fact, organic molecules have been successfully generated from abiotic elements by scientists To understand how this creation of life from abiotic material occured, we have to consider a critical idea. Life originated from its abiotic surroundings. Thus, it is important for us to learn about the physical and chemical environments of the primitive Earth. The atmosphere of primitive Earth cons...

Mucous Membranes Early Symptoms Gonorrhea
347 wordsGonorrhea isGonnorrhea Gonorrhea Gonorrhea is an infectious sexually transmitted disease. This disease involves the mucous membranes of the urogenital tract. Gonorrhea is much more obvious in males because they develop an acute discharge of pus from the urethra. Scarce when it starts, it becomes thicker and heavier and causes frequent urination. When urination takes place, there will be a burning sensation. If the prostate becomes infected, the passage of urine is partly obstructed. In females t...

Dengue Fever Sore Throat Viruses
593 wordsViruses are infectious agents found in almost all life forms. The viruses are made up either of DNA or RNA, surrounded by a capsid, a protein coat. Viruses are between 20 and 100 times smaller than bacteria, or about 450 nanometers (. 000014), being the largest, to 30 nanometers (0. 000001 in. ) being the smallest which make them virtually impossible to be seen by light microscopes. Viruses often damage or even kill the cells they infect. They reproduce by releasing their nucleocapsid, or a copy...

Cell Membranes Red Blood
421 wordsIn the early stages of the twentieth century, little was known about cell membranes. Until the early 1950 s, the biological cell membrane was rarely mentioned in scientific literature. It was recognised that something was probably there, but hardly anything about it was known. Considering the lack of technical equipment available a century ago, scientists such as Charles Overton and Edwin Gorter were not only exploring new territory in looking at the properties of cell membranes, but laying the ...

Billion Years Ago 5 Billion
503 wordsHow Changes In The Atmosphere, Eukarotes, And How Changes In The Atmosphere, Eukarotes, And Multicellularity Have Occured And Influenced Life On Earth About 2. 5 billion years ago, oxygen began slowly to accumulate in the atmosphere, as a result of the photosynthetic activity of the cyanobacteria. Those prokaryotes that were able to use oxygen in ATP production gained a strong advantage, and so they began to prosper and increase. Some of these cells may have evolved into modern forms of aerobic ...

Spindle Fibers Daughter Cells
451 wordsThe Process of Mitosis Mitosis The Process of Mitosis is the term used to describe cell division for replication. The product at the end of mitosis is two daughter cells both genetically identical to the original (parent) cell. This process is used for growth and repair within an organism and also for asexual reproduction. There are five main stages to mitosis, called Interphase, Prophase, Metaphase, Anaphase and Telophase. Although the process has been divided up into these stages the process o...

Carbon Dioxide And Water Green Plants
540 wordsPhotosynthesis is the Photosynthesis PHOTOSYNTHESIS Photosynthesis is the process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for almost all organisms. Oxygen is extremely important to photosynthesis, which most organisms depend on. Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. Chlorophyll is capable of conve...

Plant Cells Second Article
299 wordsThe second article Photosynthesis Photosynthesis The second article was about photosynthesis and discusses organisms that use this process. Photosynthesis is the process in which plant cells take sunlight and carbon dioxide and synthesize glucose. This process occurs in plants, algae, and some prokaryotes and protists. Many organisms can make their own food and are called autotrophs. Autotrophs can also be separated into two sets of organisms; chemo autotrophs and photographs. Photographs retain...

Made Of Proteins Binds To The Small Rna
647 wordsProteins are some of the most essential compounds on the planet. They perform a variety of tasks ranging from muscle contraction to fighting diseases. Over 50 % of the dry weight of organisms are made of proteins; this is because things like your nails and hair are made of proteins. Proteins are also components of biological membranes, and they help regulate the passage of molecules through the membranes. This is all very important to the body, but the most important function, by far, is their u...

Permeable Membrane Semi Permeable
274 wordsOsmosis, in botany and chemistry, the flow of one constituent of a solution through a membrane while the other constituents are blocked and unable to pass through the membrane. Experimentation is necessary to determine which membranes permit selective flow, or osmosis, because not all membranes act in this way. Many membranes allow all or none of the constituents of a solution to pass through; only a few allow a selective flow. In a classic demonstration of osmosis, a vertical tube containing a ...
