Drosophila has proven to be very useful tool. Because high alcohol levels has been shown to have an effect of development of the human fetus‚ we asked whether similar effects are observed and to what extent in the Drosophila. In order to test this hypothesis‚ Drosophila were treated with varying levels of alcohol at various times during embryogenesis. Our results demonstrate that as little as 10% alcohol treatme nt has profound effects on Drosophila development. In addition‚ embryogenesis was delayed

allelopathic chemicals (our I.V.) on the germination and growth (our D.V.) on radish seeds. The question proposed became‚ “Does Rose seed extract affect the germination and growth of radish seeds?” Keeping the allelopathic effects in mind‚ our working hypothesis became‚ “If radish seeds get exposed to the rose leaf extract‚ then their percent successful germination and the average length will be less than the percent successful germination and the average length of the radish seeds which do not get exposed

The savannah hypothesis consists of how the apelike ancestors moved from the dark resourceful rainforests to grassy plains‚ where life was a little harder and had to find new ways to obtain nourishment. The need for males to stay away from predators and find food by hunting

The Paper Airplane Lab Purpose: How can a paper airplane be modified so that it can fly farther? Hypothesis: To make our paper airplane fly farther‚ Naveen and I decided to bend the sharp tip of our plane down. We made this modification because the wings of the airplane enable it to fly farther since it makes the airplane stay longer in the air. We believed that because the wings enlarge the volume of the airplane‚ the air resistance on it would become more‚ making it able to stay in the air

Samuel Heidenreich Miss.Tatu Biology March 5‚ 2015 Introduction In the Mitosis lab an onion root was observed under a microscope to observe whether or not cell division takes place. Also‚ whether cells replicate in order for it to reproduce. By observing the onion root under the microscope it allows many layers to be looked at through each cell division. The goal of Mitosis is the replication of cells to produce multiple like cells. The steps involved in Mitosis are what is known as

According to our assumptions‚ women buy more items than men. This could be a result of the women’s shopping nature. Usually women going

Hand Sensitivity Are people more sensitive to cold water on their dominant hand or non-dominant hand? If a person sticks their hand in cold water‚ then their dominant hand will be able to withstand cold the longest. To conduct the experiment two bowls of the same size were filled: one with room temperature water and one with cold water (adding lots of ice). After this was done‚ each participant put both hands in each bowl (one at a time). The time was recorded how long each participants had each

human brain has tripled in size‚ with most of the growth being seen in just the last two million years. Although many explanations for the growth of the human brain have been presented‚ one hypothesis that proves to be most accurate is the Social Brain Hypothesis as presented by Robin I.M. Dunbar. This hypothesis attempts to explain the cause in brain size evolution by attributing it to social relations and social changes happening in early human populations. Homo habilis‚ the first of our genus Homo

For the first part of the experiment we found that four of the five pill bugs found their way to the leafy environment. However‚ most of their time was spent in the section of soil. For the second part of the experiment where we tested each of the pill bugs separately‚ we found that the bugs spent most or all of their time in the soil environment‚ therefore‚ composing the answer to the question of their most favored environment. The chart in image two contains the data found in the first part
