Part 2: Effects of Environment on Mitosis. Experimental Hypothesis: If we put onion root tips in IAA solution then the rate of Mitosis will increase. Null Hypothesis: There will be no difference Part 1- Post Lab Question If a cell contains a set of duplicated chromosomes‚ does it contain any more genetic information than the cell before the chromosomes were duplicated? No‚ because if it is duplicated‚ it would have the same number of chromosomes unless there was a

Section 1 : Identifying the Genetic Material Griffith’s Experiments In 1928‚ Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against pneumonia. A vaccine is a substance that is prepared from killed or weakened disease-causing agents‚ including certain bacteria. The vaccine is introduced into the body to protect the body against future infections by the disease-causing agent. Griffith discovered that harmless bacteria could turn virulent when mixed with bacteria that cause

Planning Introduction Stomata are pores on the bottom of leaves of vascular plants. The function of stomata is to allow gaseous exchange (transpiration) between the plant and the external environment (see diagrams below). This process is carried out by the plant‚ which controls the opening and closing of stomata via the guard cells. The more stomata a leaf contains the greater the rate of gas exchange and the less water it will be able to accumulate. Stomatal pores are formed between

AP Bio Essay #1 To address this problem created by the lab tech‚ I would set up an experiment like the one we did in AP biology to identify the molarity of the unknown sucrose solutions. First I would pour an equal volume of each solution into beakers labeled A‚ B‚ C‚ and D. I would also have a beaker of the same amount of distilled water to serve as a control for the experiment. Then I would obtain several baby carrots‚ 4 per beaker. I would mass the groups of 4 potatoes before placing them

Abstract: The fully propagated real time-dependent density functional theory method have been applied to study the laser--molecule interaction in 5- and 6-benzyluracil (5BU and 6BU). Different parameters like direction‚ strength‚ wavelength of the laser field have been chosen in order to obtain the most efficient excitation of molecules. Results show that the 5BU and 6BU molecular systems have different responds to the applied laser field and different‚ well defined laser field parameters can be

Biology Project Autumn Brown 3rd block Mrs. Stephens More than 2‚000 years ago‚ Aristotle began grouping plants and animals into various categories. Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way

5. Experimental Setup of the SRM Drive using Matlab Simulink The experimental setup is shown in Figures 5 and 6. Shows the GA-PID and ACO-PID controllers for a 3-phase 60KW SRM motor which are implemented & simulated by using Matlab-Simulink software program. Motor parameters used for simulation are given in Table 1. Tables 2 and 3 shows the GA-PID and ACO-PID controller’s parameters. the response of Kp‚ Ki and Kd parameters are summarized on table 4 which shows that the proportional controller
