Study Guide 4 CH. 21 Genomics – the study of whole sets of genes and their interactions. Bioinformatics – is the application of computational methods to the storage and analysis of biological data Linkage Map – maps the location of several thousand genetic markers on each chromosome Physical Map – Expresses the distance between genetic markers‚ usually as the number of base pairs along the DNA Metagenomics – DNA from a group of species (a metagenome) is collected from an environmental

process of Venus Fly Trap Siddarth Pillai Hour 3 Honors Biology The Effect of Insects on Venus Fly Traps Research Question: How long does it take for a venus fly trap to digest an insect? I. Introduction: Venus Fly Traps are both heterotrophs and autotrophs meaning that they create their own food and get food from other insects. The Venus flytrap is known as the Dionea muscipula; it is a carnivorous plant native to the swamplands of North and South Carolina. The plant has two primary regions:

Answers to Photosynthesis Practice AP Biology 1. Draw a picture of the chloroplast and label the stroma‚ thylakoid‚ thylakoid lumen (space)‚ inner membrane‚ outer membrane. 2. Using 18O as the basis of your discussion‚ explain how we know that the oxygen released in photosynthesis comes from water. When the oxygen in water has the radioactively labeled oxygen‚ the gas released from photosynthesis also has the labeled oxygen. This shows that the oxygen gas given off during photosynthesis comes from

ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms. It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi)‚ and needs energy. The overall reaction sequence is: ADP + Pi → ATP‚ where ADP and Pi are joined together by ATPsynthase Energy is often released in the form of protium or H+‚ moving down an electrochemical

evolution The phenomenon that populations of organisms change over the course of many generations. As a result‚ some organisms become more successful at survival and reproduction natural selection The process that eliminates those individuals that are less likely to survive and reproduce in a particular environment‚ while allowing other individuals with traits that confer greater reproductive success to increase in numbers. Directional selection is when natural selection favors a specific

synthesis from other compounds‚ as well as‚ from food sources. Nutrients are generally divided into 2 categories‚ macronutrients‚ and micronutrients. People are heterotrophs. A heterotroph is a creature that must ingest biomass to obtain its energy and nutrition. All heterotrophs have an absolute dependence on the biological products of autotrophs for their sustenance—they have no other source of nourishment. 1. Macronutrients are fats‚ carbohydrates and proteins. All three can serve as source of
