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

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

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

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

Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden skewer •

The Interaction Hypothesis (IH) is attributed to Michael Long (1981) is based primarily on the work of Stephen Krashen and Evelyn Hatch. Long emphasized the importance of comprehensible input that was central to Krashen’s Input Hypothesis but claimed that this input was most likely to be acquired during interactions which involved discourse modifications. This claim supported that of Hatch (1978) who showed a direct link between the way learners acquired a second language (l2) and the interactions

of statistics is levels of measurement. This method has four levels of measurement‚ ratio‚ ordinal‚ nominal‚ and interval. All four of these measurements are different in use. The Null hypothesis is another method that is an interpretation of statistical information‚ which involves the development of a null hypothesis in which the assumption is related to the proposed cause (Wegner‚ 2010).
