we call it allometric growth. The term‚ isometric growth‚ is used when describing body parts which maintain the same ratio throughout development. The purpose of this experiment is to determine whether two chosen body parts of classmates‚ arm and head‚ have grown isometrically or allometrically to height by comparing the ratios calculated from our measurements to the ratios of newborn body parts calculated from the measurements provided in the chart on page 66 of our lab book. We predict that the

Transformation of Bacterial Cells with Plasmid DNA Introduction: Transformation refers to the process in which the cell integrates foreign DNA to its genetic code‚ meaning it takes the genes and incorporates them into the cell’s current DNA. Cells that can do this naturally‚ most commonly bacteria and archea‚ are known as competent. The bacteria E. coli do not have high transformation competence under normal conditions‚ but can be manipulated to produce better results using

Project Title: Examination of bacterial content of sea water samples from selected sites in South East England Introduction Over the past few years coastal beaches across the UK has seen lavished with recognition for their cleanliness‚ by sections of the media and various organisarions. Majority of these beaches have been awarded the Blue flag award in recognition for meeting set criteria on various standard including cleanliness‚ water quality‚ environmental management and environmental education

BACTERIAL MENINGITIS BY JAY DOMANTAY JAY DOMANTAY ANATOMY 151 HERBERT MAY 11‚ 2009 BACTERIAL MENINGITIS A bacterial infection of blood poisoning in the meninges called bacterial meningitis affects toddlers‚ adolescents and young adults. The infection strikes nearly 3‚000 Americans each year‚ and 10 to 12% of those infected will die. Among those who survive‚ approximately 20 % live with permanent disabilities‚ such as brain damage‚ kidney disease‚ hearing loss or loss of limbs.(“Prevention

conjunctivitis can occur in one or two of a person’s eyes. It tends to cause a watery discharge while conjunctivitis caused by bacteria causes a thicker discharge. Both are transmitted to another eye in the discharge. Children are primarily affected by bacterial conjunctivitis‚ possibly because it is more transferable in a location like school. People are at a higher risk of developing conjunctivitis if they use contacts. Those who come in

Bacterial biosensors for victual processing The biosensor research has blossomed into a mature and highly active field over the past 20 years‚ mutually in the laboratory and in the business-related district‚ attract huge attention due to the pledge of holdings for vital aspects of the human life. The wished-for work aims to engineer a capacitive biosensor‚ which will be able to perform label-free and fast electrochemically immune-detection based on very small biological samples. This

Lauren Seymour- Growth and Decay Procedure: For the growth part of this lab‚ we started with 4 M&M’s in the cup. We shook the cup and poured the M&M’s onto a napkin. Then‚ we counted the number of M&M’s that had the “M” facing up. Next we added a new M&M for each one that was facing up and continued this process until all of our M&Ms were used (11 trials). For the decay section of this lab we began with a full cup of M&Ms. We shook the cup and poured all of the M&M’s

OBSERVATION OF BACTERIAL CELLS VIA MICROSCOPE In this experiment‚ we have learned several basic molecular biology techniques. Here they are; Simple staining: Only one type of dye used for simple staining and it stains all cells the same color. Creating contrast between cell and background to observe cell morphology is aimed. Differential staining: A differential stain uses more than one dye and stains different kinds of organism with different colors. Positive staining: If cell itself is stained

Cellulitis is a bacterial infection that affects the skin and the tissue underneath the skin. Although cellulitis can be caused by many types of bacteria‚ streptococcus and staphylococcus are the main bacteria that cause this condition. Cellulitis often develops near surgical wounds or ulcers. This condition causes the skin to become reddened and swollen. It also causes the area to feel tender and hot. Cellulitis can quickly spread to other areas of the body. It is not contagious. Cellulitis can
