Every day, I would drag myself to school, do my work, get home, do homework, then go to bed. For years, on and on every single day using the same method, repeating the same pattern. “Go to page 247 in your textbook.” “Find the circumference of the circle provided.” “Identify the organisms as prokaryotic or eukaryotic.” I felt that my life couldn’t get any worse, that everybody had it better off than me. I hated every single hour of the day, every single day of the week. I used to wear a fake mask to make it seem like everything was okay, all was well, when all I was doing was living a lie. Then I read your book, “Finding Spirit Bear”. My english teacher assigned us the book as an assignment for class, which I sped through, just to get it over
Eukaryotic Cells are Deemed as a Result of the Evolution of Symbiotic Prokaryotes Both Prokaryotic and Eukaryotic cells over time have sustained very dynamic changes from one another. More specifically we have seen the appearance of a more complicated and organized cell structure, the nucleus. However the big question amongst scientists today is how did these changes first occur? A fundamental concept of this evolution is the belief in the natural progression 'from the simple, to the more complex.' However one popular theory that argues that Prokaryotic symbiosis was responsible for forming the Eukaryotic nucleus is the 'Endosymbiotic Theory' this theory was first proposed by a former Boston University Biologist known as Lynn Margulis in the 1960's.
During her presentation, Bonnie Bassler expends many different aspects of communication in a bacterial level and how successful communication is important to survival and efficient functioning. It is evident from her presentation that without a common language to communicate with, bacteria could not work as efficiently as they do, neither to immunize people nor create havoc in them. In her presentation, Bassler asserts the importance of the use of language in communication in bacteria, using rhetorical appeals – logical, ethical and emotional – and how it is consequently related to humans.
There are three main divisions of living organisms: Prokaryotes, eukaryotes and archaea. This essay will outline the division between the prokaryotic and eukaryotic organisms and explore the reasoning behind such differences with regard to general structure, storage of deoxyribonucleic acid and its replication, metabolic processes, protein synthesis and ribonucleic acid processing.
The next morning, it was such a strenuous struggle to rise from my bed, I could have sworn I had been lying in quicksand all night. Walking in school was like swimming in a thick marsh. I had nothing to look forward to. Thursdays used to be the greatest day of the week, but now, all Thursdays held was gloom. That day, all I knew was despair, and it smothered me. This went on until I met up with a friend o...
To understand the human gut health and aetiology, the first step is to understand the gastrointestinal (GI) microflora and its distribution through the digestive system [2]. The human GI tract is inhabited by trillions of microorganisms, which together is known as the microbiota [5]. These microorganisms come from both archeal and bacterial domains. Bacteria are the predominant kingdom of organisms and it is composed mainly by five bacterial phyla: Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria and Verrucomicrobia [3]. The great majority of mammalian gut microbiota belongs to the three phyla: the Gram-negative anaerobe Bacteroidetes, the Gram-positive Actinobacteria and Firmicutes [5].
A Prokaryote is a single cell organisms that does not have a nucleus, which is divided into two major groups: archaeabacteria and bacteria. Prokaryotes are usually found in three common structures, such as bacillus is rod shaped, crocus is spherical-shaped, and spirillum is long shape. Although there are prokaryotes that are responsible for diseases there are also good types of bacteria that we need. Prokaryotes provide essential services to biological systems for instance food and agriculture.
...a half years ago, I figured that compared to most people, I was fairly aware. Since then, the most important thing I’ve learned is how much I don’t know. I don’t know what it is like to go to class and be the only dark spot on white linen. I don’t know what it is like to have to fight mentally, physically, and spiritually to preserve a cultural identity. I don’t know what it is like to fear running at night. I don’t know what it is like to be feared if I run at night. I don’t know what it is like to live under a shroud of stereotypes. I don’t know what it is like to have people who instruct me subtly ignore me and people who sit next to me subtly avoid me.
Humans need various things in our lives in order for us to continue our growth. When we are infants, we need milk to meet our daily nutritional values. As we get older we need plenty of physical activity. We also need to rest often to allow our bodies a chance to repair themselves. Microbes are no different in that they need many things for them to survive and grow. In the following paragraphs, I’d like to look at five factors that can affect a microbe’s ability to grow.
Hats off to bacteria! This article summarizes that bacteria are good for our body and help us function a lot better. Bacteria live in our guts, in our mouths, and on our skin. Overuse of antibiotics has disturbed the bacterial ecosystem, possibly so much that it is irreversible. In 1999 Lawrence Brandt a professor of medicine and surgery at the Albert Einstein College of medicine had success when trying to help a patient combat diarrhea induced by clostridium difficile. A patient developed diarrhea after taking a course of antibiotics for sinusitis; nothing could shake her C.difficile infection. Brandt reasoned the initial antibiotic treatment had killed gut bacteria that promote digestive health; not knowing which strain to replace, he transplanted stool form her husband. That night she reported marked improvement- for the first time in six months. This procedure has helped patients, but hopefully in the future doctors will be able to administer the particular strain of bacteria that is needed. 99% of the bacteria we harbor are resistant to culture in the lab. It was this impossible to study bacteria until the last decade or so, when DNA sequencing techniques allowed researchers to obtain gene sequences from as little as one bacterial cell. With this researchers found that bacteria cells in our bodies outnumber our human cells. Bacterial exposure throughout our lifetime is needed for our wellbeing, thinking, and functioning, contributing to conditions such as diabetes, obesity, allergies, asthma, and atherosclerosis, as well as to anxiety and mood and cognition disorders. These conditions have become more prominent because of our obsession with sanitation has eliminated the exposure to bacteria humans used to routinely get throu...
Soon thereafter my parents split up and I could feel their discord; like vibrations of hate upon snapping wires. They seemed to become somehow physically incapable of co-habiting the same spaces. It was as if something physiological that was once inside them was taken from them. Stolen was that strange organ that makes people feel the sincere need to be near someone else. As I grew older I began to observe my mother and her bizarre behaviors. Her anxious isolations and her pill bottle like a Xanax Barbie stuck to her hand. She was always so far away from me. I would sit and wonder where she would go; off to some corner of her mind where up was down and all the wrong in life was right. She was safe behind a closed door; in silence and stillness. I was always alone; and always lonely, with my mother in the next room. She may as well have been a million miles away from me. The older I got the colder the hugs became; it was like she was tired of faking it.
To many, prokaryotes may seem as uninteresting, insignificant organisms, but to biologists, prokaryotes have the greatest success story in the history of life.
At the end of my mat was the other end of the cell. The wall hovered over me like a tall, ominous castle. Small blocks protruded from beneath the thick, smooth paint and stared at me. A long, thin ray of light replicated the thin, long, dirty piece of glass that was probably trying to mimic a window. It was about three inches wide and a good meter in length. Sometimes, I stare out that window at the world outside, at the people walking freely on the streets two stories below. I wonder if they appreciate the freedom they have. I wonder if they appreciate the smell of the air. I wonder if they appreciate the nice, big windows they look through when they go home. Home. I wonder if they appreciate home. I know I didn't before. No. I didn't appreciate any of that; at least not the way I will when I can have them again.
Prokaryotic Cells All living things are made of cells, and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms, and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (monera, the bacteria) and those of the other four kingdoms (animals, plants, fungi and protoctista), which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells, and do not have a nucleus. Prokaryotic means 'pre-nucleus' and eukaryotic means 'true nucleus'.
For the prokaryotes, life arose on earth about four billion years ago; they are the original inhabitants of this planet. For approximately two billion years, they were the only form of life on earth. They have since then continued to adapt and flourish on an evolving earth. They are by far the simplest of cells and were the first to evolve. Out of all organisms, prokaryotes are the smallest and least complex cells. They are too small to be seen except with the aid of a microscope. The prokaryote cell represents the simplest grade of organism of life. About 1,500 distinct species of prokaryotes are recognized. This number is probably less that one percent of all the species in nature.
I stopped walking and looked up at the faint stars. The seagulls were flying overhead. They were screeching and swooping at the water. I started to wish I were one of them, flying free without any restrictions or limits. I listened to their voice, the screech. Deep down in I could understand what they were saying. I can't explain it, but I was so in love with the moment I thought I saw things as they did. I was in company of animals that had no concept of time, and no worries, and I was contempt with that. I closed my eyes and the faint sun warmed my face, as if shining only for me. The warmth made ...
