SCI 207 NEW WEEK 2 LAB 2 WATER QUALITY AND CONTAMINATION http://www.homeworkproviders.com/shop/sci-207-new-week-2-lab-2-water-quality-and-contamination/ Lab 2 – Experiment 1: Effects of Groundwater Contamination Table 1: Water Observations (Smell, Color, Etc.) Beaker Observations 1 To me this is just water, there is no smell. 2 As you pour the oil in the water the oil started to bubble at the top. When stirring the oil turned into smaller bubbles. It looks as if the oil has placed a thick line of film on the water 3 After pouring the vinegar in the water the only change I noticed was that the water seemed to be a shade darker when added it.
For example, Braithwaite stimulated the nociceptors by injecting dilute vinegar or bee venom under the skin of the trout. The fish found these irritating chemicals unpleasant just like a human would. The effects made the fishes gills beat faster, rub the infected area on their tank, lose appetite, and have trouble making decisions.
| Investigating Osmosis Through Living Membranes | Introduction: Diffusion is the tendency of molecules or ions to move from an area where they are in higher concentration to an area where they are in lower concentration, that is, down or along their concentration gradient (Marieb 2013). Osmosis is a special case of diffusion defined as the diffusion of a solvent, such as water, through a selectively permeable membrane (Marieb 2013). Osmosis occurs whenever the water concentration differs on the two sides of a membrane. Take a U-shaped container filled with a solution and separate the container into left and right compartments by a permeable membrane. Normally, net diffusion of both solute and water occurs until the concentration of water (and solute) is the same on both sides of the membrane (equilibrium).
From Dr. Elizabeth Monday, November 14, 2011 12:51 PM EST Hello and welcome to Just Answer! The most common thing I think of when presented with a dog with what you are describing is bilious vomiting syndrome. We suspect that in these dogs that bile refluxes back in to the stomach from the small intestine. Think of bile as soap, and its normal purpose is to help with fat digestion....the stomach is not meant to "see" bile and it is pretty noxious when it does enter the stomach. When the stomach is empty, it worsens the matter as the bile is able to reach the surface of the stomach and disrupt the normal stomach mucous barrier (then allowing gastric acid to come in contact with the stomach wall) and causes vomiting.
Some fish, though, such as Hawkfish, Lionfish, and some predatory shrimp and crabs may eat the Scarlet Skunk Cleaner Shrimp. It will not tolerate copper or high levels of nitrates in the aquarium, but will require correct levels of iodine in the water to promote proper
The same thing will happen to the dry strips of seaweed. Breaking down the properties of the seaweed to be extracted into the water. 3. Decant- gradually pour (liquid or solution) from one container to another with out disruption. 4.
For this reason fresh water fish require very efficient kidneys to remove all of the extra water, and methods of maintaining and collecting the salt lost through urination. Random fact: Some fresh water fish are said to never drink and be constantly peeing... In contrast salt water fish have the opposite problem. Their cells tend to be less salty than the environment in which they live, so the water is trying to escape. As salt water fish do not have access to fresh water to replace the water they are losing (due to osmosis), they have to constantly be drinking salty water in order to stay hydrated.
Grilled Shrimp and Garlic grits Garlic Grits with Sauteed Shrimp Grits, just like polenta or oatmeal, have a bad reputation of little flavor and mushy texture. But the grits I'm used to eating are creamy, rich, and pure delicious comfort. For mine, I like to load them up with garlic and sour cream and serve them with shrimp sauteed with creole-inspired spices. For a full creole experience, you can use your favorite spice blend or mix together garlic, onion, black and red pepper, oregano, thyme. I kept mine simple with a touch or oregano and cayenne pepper.
Salmonella Salmonella bacteria are often found in raw meat and poultry. Campylobacter In the UK, campylobacter is the most common bacterial cause of food poisoning. Campylobacter bacteria are usually found on raw or undercooked meat (particularly poultry), unpasteurised milk and untreated water. Listeria Listeria bacteria may be found in a range of chilled, ready-to-eat food, including: pre-packed sandwiches pâté butter soft cheeses, such as brie, camembert or others with a similar rind soft blue cheese cooked sliced meats smoked salmon With all of these foods it is important they are eaten by their ‘use by’ dates. Viruses The virus that most commonly causes gastrointestinal illness is the norovirus.
