Background: Bacteria is a prokaryotic cell that reproduces using the process of binary fission. Binary fission is “The process in which a parent cell splits into two daughter cells of approximately equal size”(northwestern.edu). The reproduction of bacteria can be stopped using antimicrobials. Antimicrobials were created and are used “to destroy disease-causing microbes”(cdc.gov). That means that antimicrobials fight and destroy organism such as bacteria. We use antimicrobials to clean are house

microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay‚ I will focus on some uses of bacteria in medicine‚ environment‚ and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

are chemicals or natural substances such as bacteria‚ fungi‚ as well as synthetic drugs; that inhibit or kill microbes in small amounts. Chemotherapeutic agents are antimicrobial chemicals (natural or synthetic) that can be used internally or may be absorbed. The purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this

The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes

heart‚ the blood‚ and a system of transporting vessels. A human heart has four chambers: a right and left atrium and a right and left ventricle. The fist-sized heart sits in its own sac (the pericardium) in the middle of the chest under the sternum. In most people‚ the apex of the heart points to the left. There are two circuits of simultaneous blood flow in humans: a pulmonary circuit and a systemic circuit. In the pulmonary circuit‚ the right ventricle pumps deoxygenated blood to the lungs

but the main focus is to oxygenate the blood. The body does this through one of the bodies organs‚ the lungs. Low oxygenated blood is pumped through the pulmonary arteries to the lungs. Whenever we breathe this low oxygen blood is turned back into oxygenated blood when carbon dioxide is forced into the air and oxygen reenters the body. The reoxygenated blood then reenters the heart. For this lab‚ the expected outcomes are that when the heart rate and blood pressure are measured‚ both will increase

Topic: Human Cardiovascular Physiology- Blood Pressure and Pulse Rate Determination. Hypothesis: Exercise can raise the blood pressure and the pulse rate. Aim: To determine the effect of exercise on the blood pressure and the pulse rates of students in the class. Introduction: The blood pressure of a person is the force exerted by the blood on the walls of the arteries per unit area. The blood pressure unit is mmHg. The blood pressure of an individual is expressed in two ways‚ the systolic (due

this exercise is to be able to identify and correctly name the major tissue types in the body‚ as well as identifying the subcatergories of tissue types while observing them through the microscope and diagrams‚ and be able to explain the location and function of the tissue types in the body. There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used.
