bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with the bacteria. Also‚ the ions

because they had a teacher. A teacher is defined as someone who gives instruction and communicates skills. Our children are our future‚ and they need to be prepared for the future or they will not be successful in the working world. Teaching makes a difference in them‚ because it gives them tools to help them be successful in the future. I would like to tell you why I would like to become a special education teacher and what has led me to this decision and why I want to become a teacher. I

The topic I chose to write my essay about is being an early childhood teacher because that is what I am studying to be. I have also learned a lot of interesting facts while doing my research. Being an early childhood teacher makes it so the teacher is also a guide to the children they are teaching and is also able to teach the children new things‚ and keep them safe from any harm that could come their way. As a teacher‚ you should find some new experiences for the children so they can have fun

I’ve been a special education teacher for seven years. My first three years were spent working in a Title 1 school with some of the most economically disadvantaged children in our area. I call those my "Trial By Fire" years. Almost every child on my caseload had a heartbreaking story attached to their IEP. I cried a lot those years. I quit going to church because it was too hard for me to sit in the sanctuary full of upper middle class people that had no clue of the horrors I was seeing. That

Artificial selection is the process in which desired traits are intentionally chose to breed among individuals. Antibacterial resistance is the process in which strong and highly resistant bacterial is selected against weaker bacterial. The selected bacterial then continue to reproduce and create a stronger bacterial population‚ which is resistant to antibacterial materials. Antibacterial resistance is the result of natural selection because the bacterial with highly adaptable

The two techniques that were used to create a DNA profile in this experiment were PCR and gel electrophoresis. The PCR is used to amplify the several DNA samples and gel electrophoresis is performed to separate the DNA fragments according to their size. [6] In the first part of the experiment‚ PCR amplification of the DNA templates was performed and the products obtained were used to perform gel electrophoresis. The process of PCR allows for the amplification of the DNA samples and the components

What is salmonella? According to the Mayo Clinic Salmonella infection is a common bacterial disease that affects the intestinal tract. Salmonella bacteria typically live in animal and human intestines and are shed through feces. Humans become infected most frequently through contaminated water or food sources. Salmonella serotype Typhimurium and Salmonella serotype Enteritidis are the most common in the United States. (Centers for Disease Control and Prevention) The infectious agent (pathogen)
