- Bacteria live almost everywhere, even where other forms of life can?t. The only places? where they can?t survive is in sanitized places. Some bacteria need oxygen to survive, and others don?t need any. Also some can survive with both, but some can?t survive with oxygen.
- Bacteria are one celled organisms that are found almost everywhere. Bacteria live in soil, air, water and food. They also live in and on plants and animals. Bacteria can be found on our bodies in places such as our noses, mouths and intestines. Most bacteria measure from 0.
- Bacteria are microscopic singular celled organisms grouped in the prokaryote kingdom. They have a seemingly simple internal structure but that is not so the internal structure of a bacterium is quite complicated . Bacterial growth is generally studied in cell cultures by ?visible count? estimation which shows an apparent growth curve.
- BACTERIA ( Gr. bakterion, “little staff”), group of microscopic, unicellular organisms that lack a distinct nucleus and that usually reproduce by cell division. are tiny, ranging from 1 to 10 micrometers (1 micrometer equals 1/25, in), and are extremely variable in the ways they obtain energy and nourishment.
- Bacteria comes from the Greek word meaning “Little Staff” (Infopedia) (or more appropriately “Staph”) which most likely refers to some form of Bacillus, but what is bachteria and why do we need it. When most people think of the idea of little crawlies on their skin, they pretty much freak (See Jackie Plank), but we need to see is the difference between the pathogens and the helpful bacteria, the good and the bad, the yin and yang of monerans.
- The smallest living things on earth are the prokaryotic cells. Bacteria fall into the Monera Kingdom. They have a single DNA molecule in the cytoplasm. Almost all monerans have a cell wall that protects the cell and gives it its shape. Some monerans have a layer outside the cell wall called the capsule.
- I was at home minding my own business when all of a sudden and my bag got sucked back in time. I don’t know or I can’t explain really what occurred, but I found my self at the beginning of time itself. So I decided to make down my own thoughts and what I saw.
- however Darwin’s findings marked a revolution of thought and social upheaval unprecedented in Western consciousness challenging not only the scientific community, but the prominent religious institution as well.
- As I don’t know anyone in particular who has had a parasitic disease, or at least is willing to admit to having one, I will breifly go over some of what I know and have heard about these diseases. Additionally, as this topic of this paper is to go over some general knowledge about parasitic diseases, it shall be written in an informal manner, adn may stray off topic, for the sake of style and maintanance of an informal essay.
- Before we get into the various aspects of Biological warfare it is important to understand exactly what it is. According to the website designed by students in Chem 450 at Cal Poly (www.calpoly.edu/ drjones/chemwarf.html) Biological Warfare is the use of disease to harm or kill an adversary s military forces, population, food, and livestock.
- Once upon a time, in a small town near Birmingham, there lived a regular black family who was struggling for their lives in a hostile society. With three kids, Jimmy Bruce, and Kiki, the father and mother, Jarome and Martha, were subjected into working hard for their children.
- Archaebacteria, simple organisms that resemble ordinary bacteria in that they lack a well-formed nucleus and can therefore be characterized as procaryotes in the classification of living organisms. Their biochemistry differs in important ways from that of other bacteria, however, and some biologists place them in a kingdom of their own.
- But how does it work? If you want to understand genetic engineering it is best to start with some basic biology. What is a cell? A cell is the smallest living unit, the basic structural and functional unit of all living matter, whether that is a plant, an animal or a fungus.
- DNA – Deoxyribonucleic Acid – the material that codes for amino acids which form proteins, which in turn carry out functions of the cell DNA is responsible for building life Our physical characteristics, susceptibility to some diseases and disorders (e g breast cancer, sickle cell anemia), and a few behavior characteristics are passed from generation to generation through DNA DNA controls everything about the way we look, from the color of the eyes to how tall you are to the width of your feet Every person carries billions of copies of those DNA instructions DNA is a molecule made up of smalle
- “Life is beginning to cease to be a mystery and becoming practically like a cryptogram, a puzzle, a working model that can sooner or later be made.” 1 This describes what happened to the mystery of life after the new science of genetic engineering. We can cure diseases, make bigger tomatoes, and soon, we will even be able to decide how our children will look.
- Some kinds thrive under conditions that are deadly for others. So some persons suggest that forms of life quite different from those known on Earth might possibly survive on planets with conditions that are far different from conditions on Earth.
- The instance of bioluminescence is both mysterious and relatively common. Most of us have observed a meandering firefly on a hazy summer evening. Few of us have understood what processes were going on in the firefly abdomen that resulted in the emission of light by a living organism.
- In 1995, a report on the entire DNA sequence for the genome of the bacteria Haemophilus influenzae was published . Although the genomes for a number of viruses had been completed before this, H. influenzae was the first free-living organism to have it’s genome sequenced, and as such, this report remains a biological milestone.
- This report outlines the main theories of how the process of aging works. Since researchers have not discovered a universally-accepted theory of aging, the theories discussed are potential explanations of how we age. The likelihood of each hypothesis is considered roughly equal.
- Horror movies graphically reveal the ravages of killer plagues and flesh-eating bacteria, but behind this Hollywood hype is a story of real immanent danger. Antibiotic resistant strains of staph and strep are putting the lives and health of people at risk.
