Introduction: * Genetics are composed of five main areas: DNA replication‚ meiosis‚ reproduction‚ adaptation and evolution. The body is composed of 46 chromosomes (23 from your mother and 23 of your father). The genes are in your cells in the nucleus and some in the mitochondria. The genes are a small part of a long molecule called DNA. DNA is a double stranded molecule (sugar‚ phosphate and four different bases: Adenine‚ Thymine‚ Cytosine and Guanine). The bases in the DNA are

What Shapes an Ecosystem? Ecosystems are made up of: * Biotic factors- all living parts of an ecosystem (plants‚ animals‚ bacteria) * Abiotic factors- all nonliving (but natural) parts of an ecosystem (soil‚ wind‚ water) These factors together (biotic and abiotic) determine which types of organisms can live in that particular ecosystem. A habitat- the place where an organism lives- includes both biotic and abiotic factors A niche includes both the habitat of an organism and its unique

Unit 8 Textbook Notes 12.1 The N2O4-NO2 Equilibrium System When you put a sample of N2O4‚ a colorless gas‚ in a closed container at 100C a reddish-brown color starts to show. This is due to NO2 formed by the decomp. of part of the original substance. The forward and reverse reactions are taking place at the same rate. The concentrations of species present remain constant with time. These concentrations are independent of the direction from which equilibrium is approached. The equilibrium constant

Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

Chapter 23 Inference About Means Copyright © 2010 Pearson Education‚ Inc. Getting Started n n n Now that we know how to create confidence intervals and test hypotheses about proportions‚ it’d be nice to be able to do the same for means. Just as we did before‚ we will base both our confidence interval and our hypothesis test on the sampling distribution model. The Central Limit Theorem told us that the sampling distribution model for means is Normal s with mean μ and standard deviation
