ANIMAL BEHAVIOR Animal behavior: what an animal does when interacting with its environment A lot of animal’s behaviors are genetically predetermined - Ethology Study of animal behavior Didn’t exist - People Karl von Frisch Applied scientific method to study bees Figured out how bees tell other bees Konrad Lorenz and Niko Tinbergen Scandinavian Their research helped to show that some behaviors have genetic bases Nobel prize - Evolution Underlays all behavior Behaviors enhance

How does movie Gattaca relate to biology? The movie Gattaca directed by Andrew Niccol is about “a genetically inferior man assumes the identity of a superior one in order to pursue his lifelong dream of space travel”. During the process (to become as same as Jerome Morrow‚ the superior)‚ Vincent goes through lots of different operations‚ including physical and genetic operations. As we watched it and saw the operations and the doctors in the beginning of the movie‚ we connected happenings to the

Suggested answers to Practical Workbook for SBA Ch 1 Introducing biology Practical 1.1 Design an investigation of the effect of fresh pineapple on the setting of jelly Propose a hypothesis (p. 1-2) It is the fresh pineapple that causes the jelly to remain in liquid form. Design and perform an experiment (p. 1-2) 1 (Answer varies with Ss. The recommended quantity of jelly powder and water is stated on the packet of the jelly powder. Jelly will not set if it is too dilute.)

Investigate factors affecting cell membrane permeability in beetroot. Research Question: How does variation in temperature affect the permeability of cell membranes? Background Information: In this investigation I will want to identify how variations in temperature effect the permeability through the use of a beetroot. I predict that as the temperature of the water increases so will the dispersion of the pigment. Independent Variable: The temperature of water will be increased in increments of 10oC

The journey to becoming a marine biologist is one that is embarked with hard work and keen determination. When I boarded on this journey as a student majoring in marine biology‚ I have always been fascinated by ocean exploration and how new scientific discoveries have revolutionized around it. I also live with great enthusiasm for conducting oceanic research‚ and I have always envisioned myself using scientific instruments and modern day technologies to conduct such research. The Ocean and Climate

or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940).

Implementing: - 1. First‚ I gathered the necessary equipment: § Thermostatically controlled water baths § Ice § Thermometer § Stop watch § Test tubes § Photographic film (b/w) § Syringe § Test tube rack § Ruler § Scissors § O.1% trypsin made in pH7 buffer solution § Mounted needle 2. I then decided on the range of results and temperatures I was to investigate. I decided to observe 20º‚ 30º‚ 40º‚ 50º‚ 60º‚ 70º and 80º. 3. Next‚ I label each test tube with the temperature to be investigated
