    if antimicrobial concentration increases‚ then the zone of inhibition will increase because the higher the concentration‚ the more the antimicrobial will disinfect the area of bacteria and thus the zone of inhibition will increase.The results of the lab do support my hypothesis. Paragraph 2: My antimicrobial was bleach. Bleach contains hypochlorous acid which “causes bacterial proteins to unfold and stick to one another‚ making them nonfunctional and leading to cell death”(publications.nigms.nih.gov)

    Introduction: To achieve genetic experiments with haploid organisms‚ genetic strains of different genotypes must be crossed from one another. Following fertilization and meiosis‚ the meiotic products can be analyzed as the ascomycete fungus‚ Sordaria fimicola. Sordaria can be used as a model to study meiotic segregation. The trait followed was the ascospore color. Ascospore color is a single gene trait therefore it is easily observed under a light microspore. Which allele is dominant is very tough

    contains hydrated magnesium sulphate which has the formula MgSO4.xH2O. Experiment to find the value of x in a pure sample of hydrated magnesium sulphate. The method i will use is heating a known mass of magnesium sulphate to remove the water of crystallisation. x is found by weighing before and after heating to find the mass of the water then using the moles calculations to find x. The source I have used is: http://www.rsc.org/learn-chemistry/resource/res00000436/finding-the-formula-of-hydrated-copper-ii-sulfate

    Empirical Formula of a Compound INTRODUCTION Chemical formulas indicate the composition of compounds. A formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. The ratio usually consists of small whole numbers. We call a formula that gives the actual numbers of each type of atom in a compound the molecular formula. The numbers in a molecular formula will be whole number multiples of the numbers in an empirical formula. To determine

    Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

    Hugh Kim Lab Report: Stoichiometry Lab 1. Prelab Part1. 1) Create no waste = The principle that encourages chemists to not create waste at the first place rather than cleaning it up afterwards effectively shifts the chemistry more environmentally conscious‚ as creating no waste would make the experiment efficient; the reactants will be reduced to only the essential ones and the product will be maximized‚ a change that would make the experiment economic. Also‚ if chemists aim to

    Hypothesis: For an increase in a normal force‚ there will be a corresponding increase in friction. Introduction: Force is usually connected with a push or pull exerted on an object. In this experiment‚ I am using a contact force‚ a force that exists from physical contact between two things. I am pulling the spring scale‚ which measure force in Newtons (kg x m/s2)‚ and then the block is moving. Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due

    I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration
