Territory Defense in Acheta domesticus Spring 2007 Abstract The purpose of this experiment was to investigate territory defense in Acheta domesticus, the common house cricket. A three-session experiment was performed to create an ethogram, observe the interaction and the behaviors associated with both resident and intruder crickets in a territorial encounter, and observe female-male cricket-to-cricket interaction with other males present (within a given territory). The hypotheses of this experiment were that the intruder males would be more prone to initiate territorial contests and the resident male would be more likely to dominant territorial contests, as well as, win the corresponding interactions. It was found that intruder crickets were significantly more likely to initiate a territorial contest (fight for a territory) than resident crickets; however, it was also found that there was no statistical significance in the difference in territorial encounters dominated and interactions won between resident and intruder crickets. Additionally, it was also observed that there were no discernable interactions between male and female crickets when other males were present in a particular territory.
Virtual Genetics Lab Biology HL – March 15, 2009 Karry Calderon Introduction In this Virtual Genetics Lab, a computer stimulation of imaginary insects, the computer randomly picks a character with more than one phenotype. It then randomly chooses which form of the character will be dominant and which will be recessive. It also chooses whether the gene involved is autosomal or sex-linked. Objective To use the knowledge of genetics to design and interpret crosses to figure out how alleles of different genes interact (dominant/recessive) and are transmitted (autosomal/sex-linked). Materials and Methods When making the crosses of the computer stimulated imaginary insects I made sure I crossed the same phenotypes together for example (Blue Male x Blue Female), two different phenotypes (Blue Male x Pink Female) and then I would switch the male and female trait (Pink Male x Blue Female) to analyze which phenotype had a dominant or recessive genotype and if the transmission of these genes were autosomal or sex-linked.
Shown in doc. 2, Prince Ranjitsinhji of India was invited to play on the British Sussex team. It is often seen that the British have certain standards for a cricket player, but this shows they recognize the young player through his skills, not his background or caste. However, because it was published by the British, this paper could have been used as a source of propaganda. Well quoted in doc.
To identify the King of the Sports we applied six tests to each sport. The tests we applied were; agility, reaction time, power, speed, co-ordination and balance. In each lesson we played a match in the tested sport, and at the end of each lesson we rated the sport with marks out of 10 for each of the components. Results | Football | Rugby | Cricket | Tennis | Hockey | Badminton | Basketball | Agility | 8 | 8 | 6 | 7 | 7 | 9 | 7 | Reaction Time | 7 | 8 | 9 | 9 | 7 | 10 | 8 | Co-ordination | 8 | 8 | 8 | 8 | 8 | 9 | 8 | Speed | 9 | 8 | 6 | 9 | 7 | 8 | 7 | Balance | 9 | 7 | 7 | 8 | 7 | 7 | 7 | Power | 9 | 9 | 8 | 9 | 7 | 6 | 7 | 50,48,44,50,43,49,44 The results are shown in the table above and are shown in the graph. Discussion The results show that it is difficult to crown one sport as King of Sports.
Choose any decision of the House of Lords that you have studied this term in Tort, Crime, Contract or General Principles of Law, and critically examine the common law reasoning within it. (3-4 pages) BOLTON V STONE FACTS: During a cricket match, a batsman hit the cricket ball which struck and injured the respondent who was standing on highway adjoining the ground. The cricket ball was hit out of the ground even though there was a protective fence rising to seventeen feet above the cricket pitch. The distance from the striker to the fence was about seventy eight yards and that to the place where the respondent was hit was about one hundred yards. The cricket ground had been occupied and used as a cricket ground for about ninety years.

When Jardine was appointed captain of the English Cricket Team to tour Australia in the 1932/33 test series he had a meeting with Harold Larwood, a coalminer from Nottingham and a very fast opening bowler, and Bill Voce, another fast bowler to discuss ways to stop the skill of Bradman. Jardine asked both Larwood and Voce if they could bowl on leg stump thereby making the ball come up into the body of the batsman. They both agreed to this. Close-in fielders would be placed behind the wicket and the leg side and the bowler would bowl short pitched balls to the batter on this bowling line and the batsman could either duck and risk being hit or play the ball. This was later to be recognised as bodyline.
The rest of the soil had the invertebrates extracted, analysed, identified and recorded. Mite B – Velvet Mite (Eutombidium rostratus) Mite C – (phthiracarus sp) http://xespok.net/arthropoda/main.php/v/Arachnida/Oribatida/Phthiracaridae/Phthiracarus/Phthiracarus_sp_A3399a.jpg.html Method Invertebrate extraction A 15cm x 15cm quadrangle was thrown randomly 6 times over a large area of coniferous woodland (site 1) and also thrown randomly 6 times over a large area of deciduous woodland (site 2). Using a trowel, the surface litter within the quadrangle was taken with a thin layer of soil and placed into a plastic bag. A depth of 4cm of soil within the quadrangle was also taken and separately bagged. This was repeated until 12 sample bags were collected from each site (6 x surface litter and 6 x soil).
After we had taken all of our measurements we had to decide which setting we were going to fire the ball at. We chose long. We took turns firing the ball out of the spring loaded gun and calculated the velocity by recording the position degree at which the pendulum swung after the ball had collided with it. We repeated this experiment for five trials and recorded our data. Data: Procedure 1 m = .0657kg | M= .2426kg | y1= .059cm | Trial | p | y2 (m) | y2-y1 (m) | V (m/s) | Xvo (m/s) | 1 | 39⁰ | .145 | .087 | 1.31 | .315 | 2 | 38.5⁰ | .144 | .086 | 1.30 | .315 | 3 | 38.5⁰ | .143 | .084 | 1.28 | .311 | 4 | 38.5⁰ | .144 | .085 | 1.29 | .313 | 5 | 38.5⁰ | .144 | .085 | 1.29 | .313 | Our m is the mass of our ball and M is the mass of the pendulum just by itself.
9. Find the average time for each clay with different mass to hit the ground. 10.Find the speed of the parachute in each trial and the random uncertainty from the repeat trials. 11.Plot a graph of mass (x-‐axis) against time (y-‐axis) to look for a relationship. If the first graph is not linear it will be necessary to further process the data and plot further graphs to try to find a
