Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating

Chapter 12 (Part 2) Explain the principle of independent assortment and its relation to meiosis: The segregation of chromosomes in anaphase I of meiosis explains Mendel’s observation that each parent gives one allele for each trait at random to each offspring‚ regardless of whether the allele is expressed. The segregation of chromosomes at random during anaphase I explains Mendel’s observation that factors‚ or genes‚ for different traits are inherited independently of each other. Apply the

generally followed immediately by cytokinesis‚ which divides the nuclei‚ cytoplasm‚ organelles and cell membrane into two daughter cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle‚ the division of the mother cell into two daughter cells‚ each with the genetic equivalent of the parent cell. In simple terms‚ mitosis is the process where non sex cells reproduce by duplicating DNA and dividing into two identical

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

Boys’ Code of Conduct In the article “How Boys Become Men”‚ written by John Katz‚ he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel‚ The Other Wes Moore‚ both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys‚ as the book‚ The Other Wes Moore

Hugh Kim Lab Report: Stoichiometry Lab 1. Prelab Part1. 1) Create no waste = The principle that encourages chemists to not create waste at the first place rather than cleaning it up afterwards effectively shifts the chemistry more environmentally conscious‚ as creating no waste would make the experiment efficient; the reactants will be reduced to only the essential ones and the product will be maximized‚ a change that would make the experiment economic. Also‚ if chemists aim to

Title: Mitosis and amount of time spent in each phase. Introduction: The cycle of a cell roughly doubles it volume of cytoplasm and duplicates its genetic information i.e. replicated DNA. Then it divides the genetic information equally into two daughter nuclei. The cell cycle can be divided into two phases interphase and mitotic phase. The time spent in these phases depends upon the type of cell and its particular developmental or physiological state. Cells comprising rapidly growing tissues

and 2 ATP (adenosine triphosphate) molecules. The first step of glycolysis is the energy investment phase. In which 2 ATP’s are added to the Glucose molecule‚ which produces 2 ADP’s and Fructose 1‚ 6-biphosphate. This is followed by the energy payoff phase. In this phase NAD+ is reduced to NADH and ADP is reduced to ATP. The total number of ATP created is 4 and 2 NAHDH. After the energy payoff phase what is left is 2 pyruvates. Fermentation then takes place only in the absence of oxygen. In fermentation
