Viruses: Complex Molecules or Simple Life Forms? Viruses have been defined as "entities whose genomes are elements of nucleic acid that replicate inside living cells using the cellular synthetic machinery‚ and cause the synthesis of specialised elements that can transfer the genome to other cells." They are stationaryand are unable to grow. Because of all these factors‚ it is debatable whether viruses are the most complex of molecules or the simplest life forms. While the definition of living

leaves offer little resistance to running water and can be dragged through the water without tearing. Characteristics of hydrophytes: 1. A thin cuticle. Cuticles primarily prevent water loss‚ thus most hydrophytes have no need for cuticles. 2. Stomata that are open most of time because water is abundant and therefore there is no need for it to be retained in the plant. This means that guard cells on the stomata are generally inactive. 3. An increased number of stomata‚ that can be on

EXPERIMENT 2 Measurement of g: Use of a simple pendulum OBJECTIVE: To measure the acceleration due to gravity using a simple pendulum. Textbook reference: pp10-15 INTRODUCTION: Many things in nature wiggle in a periodic fashion. That is‚ they vibrate. One such example is a simple pendulum. If we suspend a mass at the end of a piece of string‚ we have a simple pendulum. Here‚ the to and fro motion represents a periodic motion used in times past to control the motion of grandfather and cuckoo
