Biology 102 Lab Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen

1. Model organisms are species that are studied to understand the biology of other organisms‚ usually humans. Fruit flies share 75% of the genes that cause certain diseases with humans. Therefore scientists can learn about human genetics by studying fruit fly genetics. This falls under the bigger principle of understanding the basic biology that all organisms have in common. Common fruit flies like Drosophila are useful when studying genetics for several reasons‚ such as their small size that makes

The Excretory System • Main functions of the excretory system are: o to concentrate wastes and expel them from the body o to regulate fluids and water within the body • Most metabolic wastes and toxins are dissolved in the body’s internal environment‚ so the maintenance of the body fluids is essential for keeping the body free of waste products enabling it to function properly. Excretion in Invertebrates and Non-mammaliam Vertebrates • Single celled organisms and simple multicellular
