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 is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows

Free Fall Rachel Shea Physics 131 Lab‚ QL Hasbrouck 210 Sept. 21‚ 2014 Abstract This experiment measures the study of motion by observing the force of gravity acting solely upon an object‚ and also measures reaction time. If an object is in free fall‚ the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf ball’s pattern of motion‚ when dropped. The main

Figure 2 of the original article which follows this foreword. There are two torques‚ gravitational and spring‚ in this system. The condition that will produce an infinite period is that the two torques balance each other exactly for any angle 0. Since the gravitational torque varies as sin 0‚ the spring torque must also. However‚ the spring torque is the product of two variables‚ the pull of the spring and the lever arm. Can we expresssin 8 as a product of two trigonometric functions? Yes‚sin 0 = 2 sin

turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the water indirectly affects the gross primary productivity in aquatic plants. To measure this you would use the light and dark bottle method. Only respiration (R) can occur in the bottle stored in

The purpose of the lab is to identify the compound based on a constant composition by performing a serious of tests. The hydrate is solid crystals compound and appears to be dry: since an ionic compound (salt) is crystallized from an aqueous solution (water)‚ by heating the hydrate the water is released from ionic structure; therefore it is possible to measure the weight of the ionic compound and calculate its ratio to the liquid in the hydrate. The goal of the lab is to establish the identity

Matthew Mannetta Simple Harmonic Motion Lab Report Introduction Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke’s Law. In this lab‚ we will observe simple harmonic motion by studying masses on springs. In the first part of this lab‚ you will determine the period‚ T‚ of the spring by observing one sliding mass that is attached to two springs with the spring constant k‚ and attached to a hanging mass by a string

Behavior of Gases and Absolute Zero Determination Lab Report Experiment 4 Introduction In this experiment we measured the relationship between temperature‚ volume‚ and pressure. Objectives: Conduct a set of experiments‚ each of which illustrates a gas law. Gather data to identify the gas law described by each activity. Complete the calculations necessary to evaluate the gas law in each activity. From your results‚ derive a single mathematical relationship that relates pressure‚ volume‚ and
