AP Biology Lab Group Rithika‚ Neil‚ Erika‚ and Vasanth Creating our own Lab Questions What Objective measures could we use to test the hypothesis about the cleansing power of antibacterial soap? Rithika: We can test our hypothesis on the cleansing power of antibacterial soap by using both petri dishes and testing the amount of bacteria on our hand before and after using the soap. We will be able to calculate the amount of colonies of bacteria by using the petri dishes. Calculat

In the first experiment to investigate how E. coli survives in food‚ bacterial growth significantly differed between my group’s nutrient agar and MAC agar plates. In courgette‚ there was moderate growth in nutrient agar while it was heavy in Mac agar. In beef broth‚ there was slight growth in nutrient agar while it was negative in MAC agar. In fresh basil‚ growth was heavy in nutrient agar while it was heavy in MAC agar. Where cottage cheese was the ingredient‚ both plates had heavy growth. For walnut

Running Head: REDUCING SPREAD OF INFECTION Reducing Spread of Infection with Use of Alcohol-Based Products vs. Hand Washing: An Evidence Based Practice Megan K. Furnish Thomas Jefferson University Introduction Have you ever ate something without washing your hands or been next to someone who sneezed? If you have then you’ve been exposed to millions of germs. The world is full of microorganisms‚ such as bacteria and viruses which can make people sick. Simple activities‚ like breathing

It is very critical in microbiology to determine the effectiveness of a chemical to either inhibit or kill an organism as it can help cure a disease. If the agent kills the bacteria‚ it is called bactericidal. If the agent inhibits the growth of bacteria‚ it is called bateriostatic. (Fundaments of Microbiology Lab Manual) The purpose of this experiment was to examine the effect different disinfectants and antiseptics‚ which are used to decrease the number of microbes‚ on Escherichia coli and Staphylococcus

The discussion on Patrick Dismuke’s condition concentrated on his incapability to improve. After reviewing his symptoms and considering possible scenarios resulting from certain kinds of treatment‚ such as the tube that delivered nutrients into his veins that "broke the barrier between blood and air" and became "a bacteria-laden Trojan horse‚ opening the door to infection"‚ we attempted to come to a consensus on what would constitute a quality life‚ as deliberated among the committee. We took into

In this review we will learn a lot of things about the effects of radiation in plants and some information about the plants and radiation. So as I go on my research I found out that‚ in moving from the water to the land‚ several living creatures had to subdue the number of problems. It must include the fortification against reproduction‚ fluid and nutrient transport‚ desiccation and ultraviolet radiation. So plants started from algae‚ it has been found in a long time photosynthesizing bacteria could

Demonstrative Speech: Hand Washing Introduction I. Attention getter – Hand washing is a task that we perform on a daily basis‚ but it is often times taken for granted. Many of us do not wash our hands the proper way‚ and many of us do not wash our hands as often as we should. II. Reason why hand washing is so important a.i. “80% of all infections are transmitted by human hands” (Fudin‚ 2011). a.ii. “Each year‚ 40 million Americans get sick from hand-borne bacteria‚ and 80‚000 of these people

Introduction: Lidocaine hydrochloride a local anaesthetic drug is widely used in skin anaesthesia. Rapid achievement of dermal anaesthesia without discomfort and pain is both disusable and difficult. Also the topical delivery of the drugs reaches the systemic circulation only in sub-therapeutic concentrations due to poor permeation and immiscible nature of the drug at skin pH. These limitations can by overcome by iontophoresis technique. Objective: The aim of the present study is to develop the invitro

During the 19th century‚ there was a phase of mysterious deaths that occurred. This was also the time when green wallpaper was the must-have decoration in every household. People flocked to buy anything with this with green pigment‚ but green wallpaper was the main target. A man named William Morris was a founder of the British Arts and Crafts movement who wanted to revive the hand-crafting process of creating good and neglected the use of machinery and mass production. He became an icon for the

Clostridium tetani is a bacteria which can be found in soil and faeces‚ and causes the disease Tetanus. [Human Illnesses]. Clostridium tetani bacteria reproduce by binary fission because they are a bacteria. [St Margaret’s College]. In binary fission‚ bacteria reproduce by splitting themselves in half on a regular basis. [St Margaret’s College]. In ideal conditions‚ the Clostridium tetani bacteria may reproduce by binary fission every 20 minutes. [St Margaret’s College]. To live and reproduce by
