C) Type of pollution. 1. WATER POLLUTION — any contamination of water that has deteriorated its quality to living things. * SOURCE: There are many causes for water pollution such as effluent outfalls from factories‚ refineries and waste treatment plants. More to that‚ the contaminant that enter the water supply from the soil or groundwater systems. Soils and groundwater contain residue of human agricultural practise and improperly disposed of industrial wastes. Other than that‚ the habits

11-9-12 Article Summary In Power Failure‚ Megan Scudellari talks about mitochondrial dysfunction and how it can influence complex diseases. She introduces Douglass Wallace and talks about how he came up with this idea that maybe the mitochondria is linked to certain diseases such as Alzheimer’s and cancers. He was the first person ever to discover that mutations in mtDNA cause disease and from that point on his research began to expand. At first many scientists turned a blind eye to this theory

Investigation into finding out the Effect of the effect of osmosis In potato cells Introduction I am doing an experiment to find out the effect that osmosis has on Water solution and a Sugar solution. Osmosis is a process which water moves from an area of low concentration to an area of high concentration. I am going to record my results to see if osmosis occurs in water solution of sugar solution. Apparatus In this experiment I would need; - 1) 3 test tube 2)

The purpose of this investigation was to see if doing push ups affects one’s heart rate. It was found that the exercise that was performed did affect the heart rate. Therefore‚ doing push ups did increase the heart rate. If doing exercise increases one’s heart rate‚ then doing push ups affects the heart rate. This investigation deals with analyzing the effect on doing an exercise‚ in this case- pushups; will increase one’s heart rate. I have analyzed ten boys between the ages of fifteen and seventeen

Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living

Version 2: Identifying Dominant Plant Species 1- Hypothesis Based on the results‚ the bunchberry plant‚ with a scientific name of Cornus canadensis‚ was most frequently seen in station four‚ the ecotone‚ and second most in station five‚ the forest which is most likely in the lower forest since it has a similar environment to that of station four‚ and third most in station three‚ the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that

Osmosis Case study You are a veterinarian working in Indooroopilly and return from lunch to find a nurse treating a six year old kelpie‚ Baxter. Baxter is very lethargic‚ has an increased heart rate‚ and when you pinch his skin the fold remains visible. The owner tells you that they knew something was wrong when‚ upon returning to the outdoor car park from a three hour shopping trip‚ they saw Baxter passed out on the back seat. The temperature in the car would have been very high and Baxter

Activities 5. Why do you think stop and start codon signals are necessary for protein synthesis? These are necessary because start codons tells the tRNA to begin translating the codons into proteins and stop codons tell the tRNA to stop translating codons into proteins. They are essential in the process of producing proteins. 6. Describe the processes of transcription and translation in your own words‚ based on what you have observed in the Gizmo. Transcription: Protein synthesis process starts
