Unit One: Animal Structures and Functions‚ Answers to Review Questions Respiratory System 1. Indicate the importance of gas exchange in all living organisms. Respiration is gas exchange (Oxygen and Carbon Dioxide) with the external environment. All living things respire. Gas exchange is important so that cellular respiration can take place and energy can be made for the cells. 2. Distinguish among the terms cellular respiration‚ external respiration and internal respiration

BI 111 Study Guide Exam #1: Some of Ch. 4‚ the brief discussion summarizing Ch. 6‚ and Chptrs. 5‚ 7‚ and 8 HOW TO USE THIS STUDY GUIDE: You should be able to provide fairly detailed answers to the following questions and directions… this means you will probably use more room than is provided by the small spaces between them. Some of those answers will include things I talked about in lecture‚ as well as concepts that are explained by your textbook. You may want to reformat the guide on

Life!" This music is functioning as a tool to understand that the issues and feelings of the past can still be traced in modern works. A Morehouse college student was given the opportunity to earn extra credit by creating a video discussing mitosis and meiosis. Julien Turner took this opportunity and created a rap to the tune of “XO Tour Llif3” by Lil Uzi Vert. This video went viral across several platforms including Twitter and Facebook. Music is not simply a means of entertainment but also education

Nervous System and Sensory Organs • dorsal roots and ventral roots - connect Spinal nerves to the spinal cord • medulla -responsible for many involuntary functions such as heartbeat and breathing‚ primary communication pathway between the spinal cord and the rest of the brain‚ • cerebellum - receives input from multiple sensory receptor types and uses this information in coordination of complex body movements • pons- communication between lower and higher brain regions • midbrain- processes

REPRODUCTIVE SYSTEM Reproductive System A system of sex organs within an organism which work together for the purpose of sexual reproduction. Many nonliving substances such as fluids‚ hormones‚ and pheromones are also important accessories to there productive system. Sexual reproduction produces new individuals - Gametes (sperm & egg) formed by testes and ovaries - Fertilization produces one cell (a zygote)with one set of chromosomes from each parent - Creates genetic variation . Gonads produce

Maintaining a Balance Enzymes 1.1 Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are biological catalysts‚ meaning they are organic and speed up a chemical reaction without taking part in it. This means it has a vital role in metabolism where it ensures that the chemical reactions that make up metabolism can function fast enough to sustain life by lowering activation energy. Metabolism

Being passionate about science‚ I wonder a lot about the way I was taught science throughout school (and at college) and the way the people I know are being taught science in educational institutes. I think there is something fundamentally wrong with any approach that seeks to impose a linguistic corset on the processes involved in the understanding of science. You don’t make people good at science by making them learn answers to questions and then evaluating how well they reproduce those answers
