things‚ that if the force of the egg doesn’t have something to fall into‚ like cotton or balloons‚ then it will break‚ because the force needs to be shared or it takes over the egg. With that‚ I understood a basis of how the device should be. This lab is designed to be very innovative with making devices so that nature can be defied. An egg that is supposed to break on contact from seven meters up will be safe and won’t break. The egg drop showcases endless laws of physics‚ and it also encourages

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal conditions where there are no outside disturbances. There were weight differences in the potatoes which could have caused thicker potatoes to absorb more than others. It was a little impossible to obtain the same

Clement Organic Chemistry 2423‚ Section 304 25 October 2017 Lab 6: Natural Products I The main goal of this experiment was to employ isolation techniques to derive chemicals from two different natural sources and study their properties (Clement 91). The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

The underlining purpose of the experiment was to show that error is ok as long as you know what the flaws are and be able to explain they happened. The lab involved burning a Marshmallow‚ a CHEEZ-IT‚ a Cheeto‚ and A Chex. The heat from the burning snack food is then carried into the H2O and used to calculate the energy content. An improvement that could be made was a replacement for the paperclip; it was

This purpose of the lab was to observe and compare the reactivity of the elements within groups and the reactivity of the groups themselves. The elements of each group were reacted with fire‚ acid (HCl or HNO3)‚ or in deionized water. According to the observations‚ the most reactive group was the alkali metals. Since the alkali metals are in group 1‚ they only have one valence electron and can easily lose this electron. As you move towards the right of the periodic table‚ the number of electrons

Proteomics is the study of proteomes‚ which are groups of proteins in living systems. It is used to examine when and where proteins are being expressed‚ rate of degradation‚ modifications‚ how they interact with other proteins and more. The goal in this lab was to determine the similarities and differences in muscle proteins among 5 species of fish using SDS-PAGE and Western blotting. First‚ proteins are separated based on size. Second‚ antibodies are used to detect the protein of interest. Lastly‚ a substrate
