Using a plastic cup try to pour water on the eye from the tear duct outwards. If the foreign body remains after this, seek professional help. If you can see the foreign object in the ear and can remove it easily, carefully remove it with a pair of tweezers, trying not to push the foreign body further in the ear. Tilt the head to help the object to fall out by itself. If the foreign body is a live insect, you can kill it by putting a few drops of baby oil or vegetable oil in the ear.
The cells are then treated with a soap solution that degrades the Plasma Membrane and Nuclear Membrane, releasing the cell's contents. The soap also causes proteins and lipids to precipitate out of the solution. Salt is used to stabilize the DNA, which can then be isolated from the solution by adding a layer of ethanol, which causes the DNA to precipitate. Pre-Lab Questions 1. Why is the Banana treated with a soap solution?
The purpose of washing the test tubes thoroughly is so the chemicals don’t cross contaminate and affect the outcome of another section of the lab. Hypothesis: 1. If a substance contains lipids then when rubbed onto a paper bag a transparent or opaque spot will appear. 2. Is a substance contains starches then when iodine solution is added to the substance it will change from yellow-brown to blue-black.
The results indicate that fresh pineapple is best for digesting protein instead of using tinned pineapple. The experiment concludes that tinned pineapple is not as effective in breaking down amino acids in gelatine and that fresh pineapple digested is the process of catalysing the chemical reaction in breaking down protein. It is recommended that the use of fresh pineapple over tinned pineapple is used because results are more evident in the subdividing of proteins. This will therefore increase the speed of digesting protein, to maximise the efficiency of an athlete or performer. Introduction: There have been many studies on finding a way to digest protein quickly and efficiently.
2. Compounds that are easily oxidized can act as antioxidant to prevent other compounds from being oxidized. Vitamin A and E protect living cells from oxidative damage by acting as antioxidants. Why does adding lemon juice to fruit salad prevent browning of the fruit? When plants are cut they release a chemical called catechol and an enzyme called catechol oxidase.
When you smell caraway oil, you will get a moist wood type smell. When you smell the spearmint oil, you should smell a really strong minty smell. Not only is it really minty, but it has a slight smell of alcohol. In the second part of this lab, you will be using an analytical gas chromatography. The analytical gas chromatography will tell you the retention times of the components in your substance.
The Department of Health in the Philippines explains that poor personal hygiene can cause skin diseases and worm infestations, diarrheal diseases and dental diseases. Proper personal hygiene not only keeps you looking and smelling clean, but can also prevent the spread of
Wilson English 101 (Extra Credit) How to Grow an Avocado Tree: Have you ever eaten an avocado and wished you could do something with the enormous seed? Well, you can; with a little luck and a little skill, you can grow an attractive house plant from it. Caring for an avocado is not complicated, provided you follow a few simple rules. Wash the seed in tepid water, removing all the pulp. Suspend the seed with the broad end pointing down in a water-filled glass or jar by driving three toothpicks into the sides for support.
Once again due to this fact that CF is not curable these are only for therapeutic services. Being diagnosed as a baby is the best way to treat the symptoms as comfortable as possible. Life style changes and home remedies are also another way to get the therapeutic effectiveness. Mainly better nutrition rely the fact that the enzymes needed for digestion can’t reach your small intestine preventing food from being absorbed. In addition to enzymes replacement there is an supplemental high-calorie nutrition and special fat-soluble vitamins, extra fiber and extra salt.
Bacteria will not multiply in dry areas, but as soon as liquid is added, for instance to dried food like powdered milk and dried eggs, the products will provide ideal conditions for bacteria to multiply. However, if enough salt or sugar have been added to foods such as bacon, savoury biscuits, jam and confectionery, this will absorb the available moisture in the food so the bacteria cannot multiply as easily. It is not only moist foods that provide the right environment for bacteria, though. Moist skin or damp areas of an environment will also provide the right atmosphere for bacterial growth. Nutrients Bacteria, like all living things, need nutrients to survive.
