Input: Consider Input: Testing for the presence of proteins - Biuret test . Show students the available foods for testing. Ask them which ones they expect to contain protein. Demonstrate to students how to perform the test. Put a food item containing protein into a test tubes (i.e. milk or tofu). If it is not a liquid, add some water and mash it well. Also set up a control, a test tube containing a liquid that does not contain protein (i.e. water). Add about 2ml of Biuret reagent to the test tube. 1. If the food to be tested is liquid, go to 2. If the food to be tested is solid, make an extract. Grind crush or chop a small amount and put into a test tube to a depth of about 2cm. Add a similar amount of distilled water and stir with a glass rod. Allow to stand for a few minutes. 2. Draw up some of the clear liquid into a pipette and then First, prepare test solution by grinding vitamin C reagent tablet into a powder using a mortar and pestle or back of a spoon. Pour powder into dropper bottle and add 30ml (1 oz.) of distilled water. If testing more than one liquid, label each test tube with a marker. Fill each with 50 drops of blue vitamin C indicator solution. Nutrient solutions to be tested (made from foods you wish to test for sugar, starch, protein, fat, and vitamin C content). Food Test 1: Sugar test-Benedict's solution Benedict's solution is used to test for simple sugars, such as glucose. Put different food solutions in each cup, e.g. corn starch in water, flour in water, milk, and water. Using the dropper, add a drop or two of the iodine solution to each cup. Place a slice of a potato on a paper towel atop a paper plate and add a drop of the iodine solution to the potato slice. Note the color change. Place foods in separate test tubes. if the food is liquid, pour enough to just cover the bottom of the glass. If the food is solid (e.g., banana, apple, potato chips), crush a small amount and add. enough water to cover the bottom of the tube. Iodine test for starch the most followed method to analyze the presence of starch in the given food material. When iodine solution is mixed with starch it turns from brown to dark blue. As this happens with very small amounts of starch, iodine test is a sensitive one. Testing for starch. Glucose is sweet and dissolves in water while starch is not sweet and does not dissolve well in water. A further test to distinguish starch from glucose is to shine a beam of light through 'solutions' of each. This is also called the Tyndall Beam Effect. Dispersal only happens in starch as the large starch molecules are big enough to affect the light. This is a physical test. A chemical test for starch is to add iodine solution (red) and see if it turns blue/black in colour. It is possible to distinguish starch from other carbohydrates using this iodine solution test. For example, if iodine is added to an peeled potato then it will turn black. You could demonstrate the effect of iodine solution on starch by adding a few drops of solution to a starch powder or starch suspension in a boiling tube. You can then discuss the fact that this colour change might be hard to see in a dark green leaf until the chlorophyll is removed. The iodine turned from a red/yellow colour to a blue-black colour. The iodine turned from a red/yellow colour in certain places to a blue-black colour, where starch is stored. The iodine turned from a red/yellow colour to a blue-black colour. Query: how do you test for starch in a food

Output: Put different food solutions in each cup, e.g. corn starch in water, flour in water, milk, and water. Using the dropper, add a drop or two of the iodine solution to each cup. Place a slice of a potato on a paper towel atop a paper plate and add a drop of the iodine solution to the potato slice. Note the color change.

Input: Consider Input: This depends on who you ask and policy of the institution you visit. I have heard many places that for controlled substances the prescription is valid for 6 months. However, for me personally from experience my pharmacy would not take a prescription I had that was over 60 days over for a narcotic. The prescription must also include: 1 drug name. 2 strength. 3 dosage form. 4 quantity prescribed. 5 directions for use. 6 number of refills (if any) authorized. A prescription for a controlled substance may only be issued by a physician, dentist, podiatrist, veterinarian, mid-level practitioner, or other registered practitioner who is: 1 Authorized to prescribe controlled substances by the jurisdiction in which the practitioner is licensed to practice. A prescription for Acyclovir or any prescription drug for that matter, is good until the expiration date on the manufacture bottle that the pills originally came from. The exp iration dates are usually 3-5 years from date that the pills were made. Who May Issue. A prescription for a controlled substance may only be issued by a physician, dentist, podiatrist, veterinarian, mid-level practitioner, or other registered practitioner who is: Authorized to prescribe controlled substances by the jurisdiction in which the practitioner is licensed to practice. Non-controlled medications are good for one year from date written, controlled substances are good for 6 months from date written. A prescription for a controlled drug is valid for 28 days from the date given on the prescription. usually six months unless it's a controlled i.e. morphine, pethidine and methadone. These medicines are often misused, so have stricter legal controls on their supply to prevent them being obtained illegally. A prescription for a controlled drug is valid for 28 days from the date given on the prescription. How long is a written prescription in Utah good for in Utah? It depends on what the doctor wrote on the prescription, a valid until date is almost always included. For controlled substances like strong pain medications it will only be good for a short time until the doctor suspects the pain will go away. Other prescription medications they may be good for up to a year, but the doctor will limit the number of pills you may get each month, you cannot get a years supply up front. gb. Plan A prescription for Acyclovir or any prescription drug for that matter, is good until the expiration date on the manufacture bottle that the pills originally came from. The expiration dates are usually 3-5 years from date that the pills were made. Practitioners prescribing Schedule II controlled substances for residents of Long Term Care Facilities (LTCF) may transmit a prescription by facsimile to the dispensing pharmacy. The practitioner's agent may also transmit the prescription to the pharmacy. Query: how long is a doctor's prescription good for ?

Output: A prescription for a controlled drug is valid for 28 days from the date given on the prescription. usually six months unless it's a controlled.

Input: Consider Input: Stair Tread (Run) Length: 10 Inches Minimum Translated: This means that the horizontal distance from the edge of the stair to the back part where it stops (called the riser) should be at least 10 inches long. The following stair measurements are important: 1 The rise height or rise of each step is measured from the top of one tread to the next. It is not the physical height of the riser; the latter excludes the thickness of the tread. A person using the stairs would move this distance vertically for each step taken. Stair Tread (Run) Length: 10 Inches Minimum. 1 Translated: This means that the horizontal distance from the edge of the stair to the back part where it stops (called the riser) should be at least 10 inches long. 2 Reason: To allow a majority of your foot to have enough room to rest on the stair. Here's how to assemble it: 1 1. Use a drill or jigsaw to wallow out a hole in each triangle. 2 2. Lay everything out on your stairs (center piece and two triangles) and dry-fit your tool. 3 4. Nail the spacers to the ends of the triangles. The Stairtek 48 in. x 11-1/2 in. Prefinished The Stairtek 48 in. x 11-1/2 in. Prefinished Gunstock Red Oak Retread is ideal for resurfacing and upgrading your stairs. It offers a warm semi-gloss natural wood finish and is recommended for interior use. The larger width of lumber that is used also provides fewer pieces. These are combined and manufactured into a single stair tread instead of the individual pieces of flooring. Again, the fewer joints both in width and length, makes the treads stronger and more durable. Finally, the nosing itself is not an added piece as in the case of flooring but part of the tread itself. The Stairtek 42 in. x 11-1/2 in. Gunstock The Stairtek 42 in. x 11-1/2 in. Gunstock Red Oak Tread stands up to foot traffic and is designed to last. It offers a warm semi-gloss natural wood finish and is recommended for interior use. How to make your own stair tread gauge. First, you'll need to assemble/create a few parts: Here are the parts: 2 wing nuts, 4 washers, and 2 bolts. 2 triangle shapes. I made mine from scrap wood. The side of the triangle that faces the wall is the same depth as the stair tread. 1 center section. The same is true for length, because the flooring will be fitted end to end, length is not an important factor so shorter pieces are perfectly acceptable for flooring. When used on stair treads, narrow and short flooring create a number of issues. First, there are many visible joints.
