SC300 Big Ideas in Science Unit 2 Project In analyzing attendance of some local middle schools there seems to be a spike in student absences. After careful consideration in examining these absences there may be a link that connects them being a cause for concern. It seems that students involved with school band have a spike in absences due to sickness resulting in the same symptoms. Further investigations would want to look

Laura Henderson GY 102 Precambrian Period – The beginning of life Our planet formed from a cloud of dust and gas some 4.56 billion years ago. The Earth’s vast history is divided in four major eras: the Precambrian, the Paleozoic, the Mesozoic and the Cenozoic. The Precambrian era covers most of our planet’s history and lasted from Earth’s inception until 542 million years ago. It was during this era that the Earth became solid, the atmosphere became breathable and life emerged. There is

ScienceDaily (June 17, 2011) — Cells in the human body are constantly being exposed to stress from environmental chemicals or errors in routine cellular processes. While stress can cause damage, it can also provide the stimulus for undoing the damage. New research by a team of scientists at the University of Rochester has unveiled an important new mechanism that allows cells to recognize when they are under stress and prime the DNA repair machinery to respond to the threat of damage. Their findings

Article Summary 1 James Rollings Ottawa University Article Summary 1 Omics is a relatively newly coined term that refers to all the components taken into account collectively, and the suffix ‘ome’ is the object of investigation of the field (Bagnoli et al., 2011). Omics research has given rise to a plethora of fields such as genomics, immunomics, proteomics, and vaccinomics (Bagnoli et al., 2011). Genomics is the study of the complete collection of genes of an organism; immunomics is the

Prokaryotic and Eukaryotic Cells | | Part of our definition/description of what it means to be a living thing on Earth includes the assertion that living things are made of cells and cell products. In other words, we consider the cell to be a pretty fundamental structural aspect of life. Cells in our world come in two basic types, prokaryotic and eukaryotic. "Karyose" comes from a Greek word which means "kernel," as in a kernel of grain. In biology, we use this word root to refer to the nucleus

Taurean Bullard March 4, 2012 What is the infections agent (pathogen) that causes this infectious disease, the name of the bacteria, virus, or parasite? Staphylococcus Aureus is the infectious pathogen that can cause a variety of illnesses from minor skin infections like boils, carbunkles, cellulitis, impetigo, abcesses and of course staph infection. This pathogen can also lead to life-threatening diseases such as pnuemonia, menengitis, toxic shock syndrome, bacteremia, and sepsis. How

The wellbeing of cells is constantly dependant on their ability to interact with and adapt to their corresponding environment. Even in intense conditions it is vital that cells adapt in order to maintain their dynamic efficiency. Thermophilic bacteria, such as Bacillus stearothermophilus and Thermus aquaticus are prokaryotes which thrive in scorching temperatures; for example: in hot springs such as ‘Octopus Spring’ in Yellowstone National Park. These environmental conditions are substantially

Eukaryotic and Prokaryotic Cells Antibiotics are chemical substances that are produced by bacteria and fungi to fight or kill microorganisms. There are two types of microorganisms, and they are the Eukaryotic and Prokaryotic cells. They differ according to the cell wall size, the morphology of the ribosome and how they metabolize. These differences determine how an antibiotic therapy is chosen to treat microorganisms. The cell wall difference is the most important distinction between Prokaryotic
