University Of Botswana DEPARTMENT OF BIOLOGICAL SCIENCES BIO111: Laboratory Exercise 8 The Mutagenic Effects of UV Light Name: sharon reakae INTRODUCTION A mutation is a permanent change in the DNA sequence of a gene. Mutation rates are usually very low but there are factors that can increase the mutation rates. These factors are referred to as mutagens and conclude a range of physic-chemical agents. UV light is a mutagen that affects all living things and has an adverse effect on the

Chapter 2 IB Biology 2.1 Cell Theory 2.1.1 Outline the cell theory (2). • All organisms are composed of one or more cells • Cells are the smallest units of life • All cells come from preexisting cells • TOK: cell theory replaces the former ideas of spontaneous generation or abiogenesis in which inanimate matter assembles itself into living forms • Exception: muscle cells- more than 1 nucleus‚ very long; (fungal cells) hyphae roots- not a single unit; protoctista- not specialized to single

Introduction An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils‚ ethereal oils or aetherolea‚ or simply as the "oil of" the plant from which they were extracted‚ such as oil of clove. Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed
