Purpose: I will identify an unknown liquid by obtaining an average density & boiling point for my liquid and comparing them with the known densities & boiling points of liquids in the CRC handbook of Chemistry & Physics. I will perform these experiments using three different measuring tools (graduated cylinder‚ burette & pipette) to evaluate the precision of each one. Results: Density 1‚ 2 & 3 calculated by using graduated cylinder to obtain volume. Density 4‚ 5 & 6 calculated by using volumetric

The effect of mutations on living organisms Mutations occur when there is a change in the base sequence on the DNA strand. Most mutations have absolutely no effect due to them occurring in the introns‚ or the “junk DNA”. However some mutations occur on the exons‚ and these are the ones that can be potentially harmful to the organism‚ although in some exceptional cases random mutations can be beneficial‚ and pressured mutations are almost always beneficial to the survival of a species. Harmful

genetically modified organism (or GMO). The fish got the fluorescence from a red fluorescent protein from a sea anemone under the myosin light peptide 2 genes of zebra fish. The new green colored fish got is color from the extracted Green Fluorescent Protein that is taken from one jellyfish species called Aequorea victoria. These fish are beneficial for a lot of things including the economy‚ environment and the entertainment of the people. Some genetically modified organism has contributed to help

#2) Both Winner and Joy explore the issue of technology and control. How would you compare their two views of current technological development? Focus the comparison on a specific technology‚ such as genetically modified organisms. Technology is always in need of control. You cannot have a world that technology is in control such as the movie Terminator‚ where technology takes over. Just like human beings there is always a need for control. Both Winner and Joy explore this topic; Joy believes

The importance of carbohydrates in living organisms Carbohydrates contain carbon‚ hydrogen and oxygen in the ratio of 1.2.1.. There are many different types of carbohydrate‚ all of which are useful to living organisms. The most important carbohydrate is probable glucose. Glucose is a monosaccharide and is the monomer unit which makes up more complex polysaccharides. Two glucose molecules can be joined in a condensation reaction‚ whereby water is removed‚ for example to produce maltose‚ a disaccharide

Cells‚ Tissues and Organs of the Digestive System Living organisms all have various functioning systems within the body that enable life processes to be carried out. Each system uses different organs that coordinate with each other to carry out their functions‚ and these systems‚ organs and functions are shown below: Functioning System Related Organs Function Circulatory Heart‚ Arteries‚ Veins Transports blood through the body Digestive Mouth‚ Tongue‚ Pharynx‚ Esophagus‚ Liver‚ Stomach

Trice Riddle Mrs. Jennifer Sikes English 1020 11 February 2009 The Unknown Continent Many people know about it and have seen it on maps before but they still do not pay attention to detail or really care. People still say today that it is a country but it is a continent made up of countries. Many people describe it as the “dark continent” because it has not developed enough to be like an Asia or the Americas. Its hard to really discover what Africa is and how to define it. The land is rich

living organisms‚ the solvent (water) would have net movement across a selective permeable membrane. Osmosis only occurs when a membrane such as that of a cell is permeable to water molecules but not to specific solutes (Tortora & Derrickson 2014). Certain simple molecules such as oxygen‚ water and carbon dioxide can travel across the cell membrane by osmosis‚ a passive process similar to other forms of diffusion (Hill 2007). Not merely is it vital to several processes in living organisms‚ it also

Identification of Two Unknown Species of Bacteria in Tube #72 Introduction: There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium

A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li
