9-1 Identifying the Genetic Material Griffith’s experiments Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against the pneumonia-causing bacterium‚ S. pneumoniae. A vaccine is a substance that is prepared from killed or weakened microorganisms and is introduced into the body to protect the body against future infections by the microorganisms. Griffin worked with 2 types‚ or strains of S. Pneumonia. The first strain is enclosed in a capsule made of polysaccharides

Chapter 15/16 Worksheet Problem (1996 #2) 1) HOCl <--> OCl- + H+ Hypochlorous acid‚ HOCl‚ is a weak acid commonly used as a bleaching agent. The acid-dissociation constant‚ Ka for the reaction represented above is 3.2 x 10-8. (a) Calculate the [H+] of a 0.14-molar solution of HOCl. (2 points) (b) Write the correctly balanced net ionic equation for the reaction that occurs when NaOCl is dissolved in water and calculate the numerical value of the equilibrium constant for the reaction

AP Biology August 23‚ 2012 Egg Osmosis Lab Definition of osmosis: The diffusion of water across a selectively permeable membrane from high to low concentrations Hypothesis: If I place an egg in vinegar‚ then the outer layer of the egg is going to become slimy and look like rubber. It will also become larger and bubbles will form on and around the egg. Hypothesis: If I place an egg in corn syrup‚ then the egg will become small and the outer layer will not look like rubber any longer. Day one:

55. a) Cuticles on the outermost layer of angiosperms are clear‚ which allows for light to pass through. The leaf is shaped in a way that will allow it to absorb more sunlight and be more efficient. Photosynthesis takes place in the spongy parenchyma and the palisade parenchyma. In order to obtain food‚ it is controlled by the stoma which controls the passage of gas and water. b) Water and food is transported through the xylem. The water will eventually be transported to the leaf tissue while the

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

Nitrogen Cycle Questions 1. Nitrogen is both the __most abundant element__ and in organisms it is the raw material of two main macromolecules __ammonia and nitrite which build proteins and _nitrates which build your genetic material‚ DNA. 2. In the atmosphere it is found in the form of N2 which is __nitrogen gas____. 3. These Nitrogen molecules then need to go through a process called __nitrogen fixation__ in order to be converted into molecules that living organisms can use readily. 4. Two forms

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2.48. If the concentration inside the cell is .15 M‚ then would diffusion out of the cell and into the solution of .1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water
