Recommended: Harmful effects of radioactivity essay

The very first step of my experiment is to get all the equipments and materials I need. What I need for this experiment are six kinds of berries I chose, enough yeasts, x-ray machine and materials for comet assay. The first step of my experiment is to give berries to the yeast. I will give berries to yeast by blending the berries using the blender, and then whiz it, so I can add the juice from the berries to the yeast. While I am doing my experiment I will have to decide how much juice I add to yeast. Then after adding the juice I will x-ray the yeast with the x-ray machine, with the help of an adult. After x-raying the yeast I will use the comet assay technique to see if it damages it or no. My final step is to collect the data. Risk/ Safety As far as my experiment, on finding if the …show more content…

The only risky part of my experiment is doing x-rays. X-rays are harmful because exposing to a lot of radiation from x-ray can cause radiation sickness. As I said, x-rays are form of ionizing radiation. When normal light hits an atom, it doesn’t change the atom in any significant way, but when an x-ray hits an atom, it knocks electrons off the atom to create an ion. Ion is an electrically-charged atom. An ion's electrical charge can lead to unnatural chemical reactions inside cells. Among other things, the charge can break DNA chains. A cell with a broken strand of DNA will either die or the DNA will develop a mutation. And if a lot of cells die, the body can develop various diseases. If the DNA mutates, a cell may become cancerous, and this cancer may spread. The mutation in a sperm or an egg cell may lead to birth defects. Because of all these risks, doctors use X-rays

    Apart of becoming a new patient at a dental office is taking an x-ray and some may have question along with taking an x-ray, like “will I be affected by the x-ray?” or “will I get cancer?”, “how long will it take” “are x-ray’s safe?”, the list goes on and on. So in this paper we will talk about different types of radiation affects such as affects on children and pregnant women as well as some things that may help reduce some of the radiation that may harm the human body.

    There were five test solutions used in this experiment, water being the control, which were mixed with a yeast solution to cause fermentation. A 1ml pipetman was used to measure 1 ml of each of the test solutions and placed them in separated test tubes. The 1 ml pipetman was then used to take 1ml of the yeast solution, and placed 1ml of yeast into the five test tubes all containing 1 ml of the test solutions. A 1ml graduated pipette was placed separately in each of the test tubes and extracted 1ml of the solutions into it. Once the mixture was in the pipette, someone from the group placed a piece of parafilm securely on the open end of the pipette and upon completion removed the top part of the graduated pipette.

  • The Effects Of Radiation On A Fetus

    Many of the experts agree that the dose should be kept as low as possible with minimal exposure to the fetus of any age. It has been shown that fetuses before 16 weeks are the most sensitive to any dose of ionizing radiation and have been shown to have lower IQ’s and verbal scores than those exposed after 16 weeks. Fetuses exposed after 16 weeks have the same amount of risk as children up to 10 years old getting cancer. It is very important to take in to consideration gestational age, shielding, the position of the x-ray tube and the amount of necessity that is considered in taking a radiographic image or performing a radiographic procedure in a pregnant woman.

  • Fermentation Lab Report

    In our Biology Lab we did a laboratory experiment on fermentation, alcohol fermentation to be exact. Alcohol fermentation is a type of fermentation that produces the alcohol ethanol and CO2. In the experiment we estimated the rate of alcohol fermentation by measuring the rate of CO2 production. Both glycolysis and fermentation consist of a series of chemical reactions, each of which is catalyzed by a specific enzyme. Two of the tables substituted some of the solution glucose for two different types of solutions. They are as followed, Table #5 substituted glucose for sucrose and Table #6 substituted the glucose for pH4. The equation for alcohol fermentation consists of 6 Carbons 12 Hydrogens 6 Oxygen to produce 2 pyruvates plus 2 ATP then finally the final reaction will be 2 CO2 plus Ethanol. In the class our controlled numbers were at Table #1; their table had 15 mL Glucose, 10 mL RO water, and 10 mL of yeast which then they placed in an incubator at 37 degrees Celsius. We each then measured our own table’s fermentation flasks every 15 mins for an hour to compare to Table #1’s controlled numbers. At

    Ties and hair should be tucked out of the way, so they do not make contact with any of the chemicals. It would also be preferable to wear a scientific apron, however this is not essential. We should also try our best not to spill any chemicals, and we must not eat or drink in the lab while dealing with these harmful chemicals, as they can get on our hands. Fair Test To make this experiment a fair test, we need to make sure we do a number of things. In this experiment we are trying to find the rate of reaction using concentration as a factor, so there are a number of things we need to make sure we do to keep it a fair test.

  • X Rays Essay

    634 Words  | 2 Pages

    X-rays can cause the cells to have a higher level of peroxide which then causes cell damage, cancer, the radiation from the x-rays can cause changes in the DNA leading to mutation and radiation exposure. The people that have the highest risks when having x-rays are pregnant women, if women have too many x-rays it could possibly cause defects in the baby. However, most of these ailments only occur after copious amounts of x-rays, and one or two isn’t going to hurt. Even though there are many disadvantages to undergoing an x-ray, there are many advantages that outweigh these risks. The advantages include detecting illnesses like tumors and cancers, detecting broken or fractured limbs and locating foreign objects in the body.

    Besides all the benefits of using x-rays to see inside our bodies or objects, there are also many ethical issues. Since x-rays are the most used medical imaging, everyone thinks that it is completely safe, but that is not true. There are a few risks when using x-rays. The biggest threat is radiation because x-rays use very high energy radiation that is how it’s possible to create an image of the inside of our bodies for us to view. The high radiation levels are dangerous because of over exposure occurs.
