PROBABILITY and MENDELIAN GENETICS LAB Hypothesis: If we toss the coin(s) for many times‚ then we will have more chances to reach the prediction that we expect based on the principle of probability. Results: As for part 1: probability of the occurrence of a single event‚ the deviation of heads and tails of 20 tosses is zero‚ which means that the possibility of heads and tails is ten to ten‚ which means equally chances. The deviation of heads and tails of 30 tosses is 4‚ which means that the

(the law of the place of conclusion of the marriage). This rule is founded firmly in Roman-Dutch law and entrenched in South African case law. ( Exception: S 10 of the Marriage Act 25 of 1961 makes provision for South African diplomatic and consular officers to solemnise marriages between South Africans in the countries in which they are stationed. Such embassy marriages are deemed to have been concluded in South Africa and their formal validity is thus governed by South African law (as the

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

Post-Lab Questions 1. Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq)

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

the 70’s 80’s and 90’s Computer technology took a great leap in development during the 70’s when schools‚ businesses‚ and universities began to use computers. The 70’s would have to be the beginning of the technology of computers‚ as we know it today. The personal computer became big in the 80’s. Now computers are being updated daily‚ if not hourly. During the 70’s computers and computer use began to become known by everyone. This period was a time for development and improvement. The 70’s was where
