Fruit Fly Lab Alycia Fletcher Biology IB HL March 25th 2010 Fruit Fly Lab Introduction Genes can either be sex-linked or autosomal. If a gene appears mostly in one sex chances are the gene is sex-linked and if it appears frequently in both sexes it is most likely autosomal. Using Drosophila melanogaster‚ also known as the fruit fly‚ we will determine whether the gene is sex-linked or autosomal. Drosophila melanogasters have a relatively short life span and are an excellent organism

The Field Studies of the Mangrove Ecosystem at Bicentennial Park It might be said “Bicentennial Park is a diverse natural property”(1) which studies the ecosystem of mangroves‚ saltmarsh and other biotic and abiotic factors. Bicentennial Park is located in Sydney Olympic park‚ NSW Australia. “The state and federal government created the Park during 1980s‚ to celebrate Australia’s Bicentenary in 1988”(2). “On 1 January the Park was officially opened”(3). “This large

Between me and the athletes there were several more tables‚ all filled with energetic dancers‚ thoughtful theater kids‚ and noisy band members with their instrument cases spread over the table along with the peanut butter sandwiches and bags of carrot sticks. I didn’t feel like I matched any of these groups. At my old school‚ I was friends with everyone‚ and we didn’t have to share a hobby in order to have plenty in common. It seemed as though all of these groups shared one specific thing with each

Oral Presentation – Mending Walls The persona’s further description creates an imagery that illustrates how hard it is to maintain and balance the barrier. It reads‚ “We have to use a spell to make them (the boulders) balance‚ stay where you are until our backs are turned.” The spell‚ again cannot be true in the real world‚ shows that they need to use imaginary power to maintain balances‚ since the nature of the “boulder”‚ “balls” and “loaves”‚ or in the metaphorical terms‚ the barriers between

Science Investigatory Project Situation: Growing pechay is an easy way to earn money. It is a good way to augment the financial needs of a family especially these days when everything is expensive. This plant is also easy to grow and needs a short time before it is harvested. But since pechay has ‚limited time frame before it is harvested‚ I is essential that its growth should be maximized on the second and third week after it is transplanted. So the use of fertilizer is recommended. But commercial

What pH Level Causes a Plant to Grow Best Alexis Chavez‚ Heather Nutt‚ Nguyen Phan Introduction We knew that water is normally stated as the best form of liquid to make sure plants grow as best as they can‚ but we wanted to know if causing the water to be more basic or more acidic would affect how the plant grew. Our hypothesis was that if the plant is treated with a pH of 12 then treated with another pH. Materials The materials used were three identical plants‚ that each had 4 sections that were

As we age we seem to prefer things that are slightly sweet or “semi-sweet.” Semi meaning partial. Material with electrical conductivity that is not quite that of a conductor nor that of an insulator‚ is a semiconductor. But if semi means half why is a 80‚000 pound 18-wheeler called a “semi.” It’s more of a maxi. It’s really the trailer part that is referred to a “semi”‚ as in semi-trailer. It’s doesn’t have a front axle and only wheels only at the end. So the truck that pulls it is semi-tractor

Effect of pH on Green Pea Germination Objective: To determine how pH affects the germination of green peas and to examine the degree of germination within each pH level. We will do this by using various buffer solutions (along with distilled water) to grow green peas. Hypothesis: We expected that the group of peas that encountered a pH of 7 to have the most and highest degree of germination. Materials: tap water buffer solutions pH 3‚5‚ 7‚ 9‚11 distilled

The data from the experiment rejects my hypothesis because the rice cakes had the highest experimental Kcalories per gram but I thought that popcorn would have the highest Kcalories per gram. It was hypothesized that popcorn would have the highest amount of Kcalories per gram when burned. My claim is true in the theoretical conditions. According to the data collected in the experiment‚ it shows that rice cakes had the highest experimental Kcalories per gram at 1.141 Kcalories per gram. I hypothesized
