similar that it is hard to distinguish the corresponding difference in phenotype. | D. rerio used for animal development research | 1.) Small Size and can be bred together in high densities- Feasible to breed many D.rerio in a small space. (Research Labs have space constraints for breeding) 2.)Transparent Embryo that develops outside mother’s womb - Observing organ development at various stages is much easier. 3.) Embryo resembles that of higher vertebrates4.) Rapid Development of Embryo- Experimental

January 31‚ 2014 Mr. Robinson IB Biology I 2ND Period The Effects of Light on Plant Growth Introduction: Photosynthesis is the process in which plants use light energy‚ water‚ and carbon dioxide to produce food. Plants use the food they make for the growth and for the carrying out other life processes. Sunlight is the natural energy source for photosynthesis. White light form the sun is a mixture of all the colors of the light spectrum: red‚ orange‚ yellow‚ green‚ blue‚ and violet. Light

Lab 12: Meiosis kimberleigh Lewis Biology 1408-63400 Consider the Concepts Experiment: 1. A common misconception about meiosis appears when students identify which of the two divisions converts a diploid cell into two haploid cells. Meiosis I is the division immediately following DNA replication and replication does not occur again before meiosis II. However‚ meiosis I is the "reduction" division when a diploid cell forms two haploid cells. If the DNA duplicated before meiosis I‚ how

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

Biology Notes: Threats to biodiversity in MA 1. Climate change: temp‚ sea levels‚ precipitation 2. Non climate threats such as habitat loss‚ habitat fragmentation‚ and invasive species and air and water pollution Fragmentation: often due to man (dams‚ roads‚ and general development) Elements of biodiversity: Species‚ ecosystems & landscapes Mammals from bats to bears Bats got the white nose fungus which caused the bats to die and the insect population flourished because the bats main job

Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors

process. The data from experimentation provided sufficient results to suggest that the identity of unknown bacterium was the gram-positive spore forming bacteria‚ Bacillus Subtilis. Introduction. One of the main responsibilities of a medical lab is to determine the identity of pathogenic bacteria. It is important to determine the specific type of bacterium causing disease so the physician is able to correctly treat the patients. The structure of bacteria plays a crucial role of what antibiotics

Design Research question: This should be a clear focused question that says exactly what you are investigating. It shouldn’t be too long and it must include the dependent and independent variables. Eg. What is the effect of pH on the activity rate of salivary amylase? Dependent variable: activity rate Independent variable: pH Hypothesis: This is a paragraph or two where you explain your research question. You are going to say something like: "Salivary Amylase is a an enzyme that digests
