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

The giant amoeba is 5000 times larger than the smallest bacterium. 9. Prokaryotic and eukaryotic cells carry out the functions required for living‚ and both contain cytoplasm as well as cell membranes. Eukaryotic cells contain organelles and have a nucleus‚ whereas prokaryotic cells do not. 10. Eukaryotic;

Enzyme Lab 6 03/13/2013 Report by Mary Jo Anthony I. Introduction II. Materials and Methods III. Results IV. Conclusion and Discussion Introduction Background Information: This lab allowed us to study chemical reactions and how catalysts will affect the rate of these reactions. The reaction we studied is the breakdown of hydrogen peroxide to water and oxygen and it is vital to life. The molecule hydrogen peroxide is a molecule that is toxic

1. There are two main types of cells‚ prokaryotic and eukaryotic. The connection between the two can be seen right from their prefixes‚ pro meaning before and eu meaning true or good. This is because prokaryotic cells are before a nucleus and eukaryotic cells possess a true nucleus. This has led to many theories that eukaryotic cells have evolved from prokaryotes. The evidence for this is most noticeable in the structure of the cells‚ which will be compared below. Prokaryotic cells have no

Discussion: We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water‚ 2%‚ 5% and 10% salt (NaCl) Solution. Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt

AP BIOLOGY EXAM ESSAY (FREE RESPONSE) QUESTIONS General directions: Answers must be in essay form. Labeled diagrams may be used to supplement discussion‚ but in no case will a diagram alone suffice. It is important that you read each question completely‚ and answer each section of the question. When giving examples‚ the first ones you give will be the ones graded. (if two examples are asked for‚ and you write about 4‚ make sure the first two are the best ones; they are the only ones counted
