Julia Babin Ms. Bukola 11/6/2012 Bio Lab W 8 Cell Structure and Function Prokaryotic cells do not contain a nucleus. Eukaryotic cells do contain a nucleus. Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins

present in the mammal. The dental formulas for these three species: coyote (Canis latrans)‚ deer (Odocoileus virginanus)‚ and human (Homo sapien) are all different. The coyote had the dental formula of 3-1-4-2/3-1-4-2 (x2)‚ which produced the total of 40 teeth. The deer had the dental formula of 0-0-3-3/3-1-3-3 (x2)‚ which equaled to 32 teeth. The human species had a smaller number of teeth with the dental formula being 2-1-2-2/2-1-2-2 (x2)‚ which produced a total of 28 teeth. The numbers of molars in the

Solutions of different concentration were made from the stock solution and placed in test tubes. 2. All test tubes were labeled appropriately‚ according to table below‚ and Benedict’s test was carried out on the various dilutions for 5 minutes. 3. The colours of the solution were observed and heights of precipitate formed were recorded. The test tubes were placed in a rack and put aside to be used as a colour standard for comparison. 4. Benedict’s test was carried out on sample A. 5

TOPIC 3.7 + 8.1: CELL RESPIRATION 3.7.1 Define cell respiration. Cell respiration is the controlled release of energy from organic compounds in cells to form ATP (adenosine triphosphates). 3.7.2 State that‚ in cell respiration‚ glucose in the cytoplasm is broken down by glycolysis into pyruvate‚ with a small yield of ATP. Glycolysis in cytoplasm: Glucose 2 pyruvates + small amount of ATP (does not use oxygen) 3.7.3 Explain that‚ during anaerobic cell respiration‚ pyruvate can be
