Meiosis is the process in sexually reproducing organisms where cells divide. The cells produced during meiosis have half the chromosome number as the original cell. There are two cell divisions in meiosis‚ meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells contain only one set of chromosomes‚ which is written as n. Meiosis consists of nine phases. In meiosis the interphase l the chromosomes replicate and the centrosome duplicates in one diploid cell

AP biology FRQ Courtney DeMane 1.22.13 block 7 A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino‚ carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure‚ there are 4 levels. The first one being the primary level. These are made

With the evolution of animals living on land from animals living in the water‚ many changes needed to be made in order for survival. Each problem that these organisms may have experienced in the past has been dealt with a solution of some manner. One of the main problems was water storage. Because organisms in an aquatic environment are surrounded by water‚ they do no experience problems with water storage‚ but without an aquatic environment there are bound to be problems. The land organisms need

AP Biology Summer Assignment Chapter 50.1: An Introduction to Ecology and the Biosphere Ecology is the scientific study of how organisms interact with the environment. When studying Ecology scientists want to know‚ where organisms live‚ why they live there‚ and how many are there. Ecology and environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting

AP BIOLOGY EXAM ESSAY (FREE RESPONSE) QUESTIONS General directions: Answers must be in essay form. Labeled diagrams may be used to supplement discussion‚ but in no case will a diagram alone suffice. It is important that you read each question completely‚ and answer each section of the question. When giving examples‚ the first ones you give will be the ones graded. (if two examples are asked for‚ and you write about 4‚ make sure the first two are the best ones; they are the only ones counted

In freshman year‚ I was placed in the honors Biology course. I had a lot of difficulty the first semester and never really attempted to study much. I didn’t want the second semester to be the same as the first semester‚ so I tried a lot harder by studying for every test and doing every assignment that was given. In the end of the semester‚ I earned an A with all of my hard work. In order for students to take an AP class at our school‚ we must apply to the class with an application. Acceptance is

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
