Lab 1 : Scientific Method 20 Table 2: Water quality vs. fish population 1. Based on the information in Table 2‚ (in the lab manual) what patterns do you observe? 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. 3. What would your experimental approach be to test this hypothesis? 4. What are the independent and dependent variables? 5. What would be your control? 6. What type of graph would

Cell Biology Lab - Homework 1 Due to the week of Oct. 6-10th This is NOT a lab group project. Do the work individually. You may use any source other than your fellow students. Show your work‚ use your own words and cite all references. 1. (20 points) The HeLa S3 cancer cell line is considered to be “continuous” due to acquired mutations that enable the cells to evade senescence. This property is one of several hallmark characteristics of cancer cell lines. Describe three hallmark characteristics

Assess the pros and cons of angel investing using Nova Flo as an example. Nova Flo for introduction is purchased and utilized in the United States Of America‚ Canada‚ Mexico also in the far east. Nova Flo is a non electrical magnetically operational device that senses water levels in the bath or basin area. The water will shut off automatically to prevent flood damage and water usage overuse. With proper install this mechanism is a secondary type of insurance policy.

The Variation of Yeast Cells When Adding an Antibiotic Biology 1401- A October 21‚ 2013 Abstract. -- The main focus in this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was

Position Paper #2 Fingerprinting At Birth I think that having everyone fingerprinted at birth is a great idea for many reasons. First off‚ it can help if something was to happen to you and they needed to identify you by your fingerprints. Second‚ it can help more in crimes. Lastly‚ it can help if someone is kidnapped. Now-a-days‚ people are more violent and things happen more frequently than it should. People go missing and turn up dead. Some people are so badly damaged that they cannot be identified

1. Describe the function of the following pieces of safety equipment and how each might be used: a. Eye wash- To be used in the event of a chemical splash to the eyes. Should be used to flood the eyes for at least 15-30 minutes with water‚ flooding from the eye outward. b. Fire Blanket- To be used in the case of a small fire. Would be tossed onto flames to suffocate the flow of oxygen. c. Shower- Safety showers are designed to flood your body with water in the event of a fire or chemical spill

DNA replication mechanism is an integral and the most important part of cell division. It is a complicated mechanism that requires a lot of steps and different enzymes. Many scientists were trying to understand the mechanism of DNA replication and its role in the transfer of the hereditary information to the offsprings. DNA replication begins with a single origin of replication that starts off the process by creating a replication bubble. In many eukaryotic cells‚ the DNA strand will have more than

for the DNA ligation‚ in which the gene products with sticky ends will be inserted to a plasmid vector. Also‚ to transform E.coli DH5α cells by introducing the plasmids DNA which contains the gene of interests into the E.coli strain(DH5α). The plasmid DNA can replicate inside the transformed E.coli DH5α cells‚ only successful transformed cells can produce the protein that is resistance to kanamycin‚ this allows for the selection of successful transformed cells. 2.
