ORGANIC MATTER AND INORGANIC MATTE Organic matter is that which is living or has been alive‚ e.g. wood or coal. Inorganic matter is that which is not living and never has been alive‚ e.g. water or iron. Inorganic substances can be built up into organic compounds by living organisms. All living matter is made up of small units called cells. Some organisms‚ such as bacteria‚ consist of one single cell; others‚ like human beings‚ consist of many hundreds of millions of cells‚ all functioning together

courses. According to the College Board’s website‚ AP Biology courses are designed to be the equivalent of a college introductory course‚ usually taken during a biology major’s first year of college. Students who choose to take AP Biology may be allowed to skip over introductory biology courses and enroll in courses in which biology is a prerequisite. Because universities grant college credit for this course‚ they require that the textbooks‚ labs‚ and coursework used by AP courses be equivalent to

Biology Lab Report 7 “Independent Assortment & Dihybrid Cross” 10-22-2013 Biology 202 Introduction: In genetics‚ when crossing a purebred white flower with a purple flower‚ we might expect its offspring to be a blend of both colors. Instead‚ we see that its offspring is purple as well. This is led to be by one trait being dominant over another trait. Gregor Mendel came up with a theory that each member of a pair of homologous chromosomes separates independently

Australian Ectotherms and Endotherms- temperature regulation Part A :Types of Temperature regulation 1. Write down the meaning of the terms endotherm and ectotherm. Consult a textbook if necessary. a. endotherm Endotherms are animals that can maintain a constant internal body temperature. For instance mammals and birds are true endotherms that can maintain a constant internal body temperature b. ectotherm Ectotherms are animals that are not able to regulate their body temperature or in simple
