In one sentence, describe what the following article is about: Remove the old dressing and replace it with a fresh one. Do this 3 times a day so the wound stays clean. For example, you may change the dressing at night before bed or when you wake up in the morning. Make sure the wound stays covered throughout the day, as this will help it to stay moist. Keeping the wound moist will ensure it heals properly and reduces the chances of scarring. The only time you should uncover the wound is in the shower, as the moisture and water will help the wound heal. If the bandage gets bloody, replace it with a clean dressing. If the bandages continue to get soiled quickly, go the doctor as soon as you can; this means that the wound is continuing to bleed or drain. If you see that the wound is getting infected, go to the doctor right away. Your doctor can clean and treat the wound so it can get better. They may also prescribe an oral antibiotic to clear up the infection. To determine if there’s an infection, see if the wound is:  Swollen Hot to the touch Very red Draining pus Irritated Painful Most minor wounds will heal with the right care within 2 weeks. If the wound is not very deep or large, it may heal without scarring. Wounds that are deeper and larger may scar. If a minor wound does not heal or get better after 1-2 weeks, go to the doctor.
Summary: Change the dressing 3 times a day. Keep the wound moist and covered. Replace the bandage if you see blood soaking through. Go to the doctor if you see signs of infection. Allow the wound to heal for 1-2 weeks.

Testing kits include various bottles of nitric acid for different types of gold. Some tests also include a flat rock called a touchstone you can use to scratch off some of the gold on your item. You may also see needles with samples of yellow and white gold to use as a comparison to your item. Testing kits are available online. Also, check with local jewelry stores. Most jewelers use this test for its accuracy. Choose an inconspicuous location on the jewelry to make the scratch, such as underneath a clasp or an inner band. Then, use a sharp tool such as a jewelry engraver to dig into the gold. Scratch until you get underneath the top layer of gold. Expose a fresh layer of gold or any other metal underneath it. Nitric acid tests require you to scratch your piece of gold. If the gold has personal value to you or you plan on keeping it, take it to a professional jeweler instead of doing the test yourself. Put on latex gloves and work in a well-ventilated room to avoid any issues with the dangerous acid. When you’re ready, look for the bottle of acid labeled for 18K gold. After setting the gold in a stainless steel container, place a drop of the acid directly on the scratch you made, then watch for it to turn a shade of green. If it turns green, you know right away your gold is fake.  Regular gold does not react to the acid, so your item might be gold plated or a low-purity blend of metals. A milk-colored reaction usually indicates gold-plated sterling silver. If the acid turns gold, you have gold-plated brass. If you think you might have real gold, rub it along the touchstone to create a streak of gold flakes. Add a drop of 12K, 14K, 18K, and 22K nitric acid to different parts of the streak. Check back after 20 to 40 seconds. Find the spot where the acid doesn’t dissolve the gold to figure out what karat rating your item is. The acids all increase in strength, so the acid used for 22K is stronger than the 12K one. If the 18K acid dissolves the gold but the 14K one doesn’t, you know your item is probably around 14K.

One-sentence summary -- Purchase gold-testing kit to get the acid you need for the test. Create a small scratch on the gold using a sharp tool. Add a drop of nitric acid to the scratch. Scratch the gold on a touchstone to test its purity.

Q: To avoid wasting time looking for things, have all your books, papers, writing utensils, and other materials readily available and easy to get to. Clean out your backpack and binder(s) weekly or monthly to stay organized. Consider consolidating your multiple different subject folders and notebooks into one big binder separated by tab dividers. This way, all of your schoolwork will be in one place. Instead of just grabbing the first book in your backpack and starting the work, plan ahead. There are several ways that you can plan out how to do your homework for the evening, including:  Decide how much time you want to spend on your homework collectively. Make a list of all the different tasks you need to finish. Estimate how much time you’ll be able to spend on each task to finish your homework when you want to. Work straight through your list and cross tasks off as you go. Waiting too long in the evening to start may result in working late into the night, which isn’t good because it’s much harder to work quickly when you’re tired. Similarly, waiting until the next morning to do your homework will probably result in a rushed or incomplete end result. As you write assignments down in your planner throughout the week, make sure to write an “A” next to high priority tasks, a “C” next to lower priority tasks, and a “B” next to tasks that fall somewhere in between. An assignment that has to be completed by the next day would probably take priority over one that’s due next Tuesday. Also prioritize bigger assignments over smaller ones.  A ten page essay that’s due in a week that you haven’t started should be labeled an “A” or “B” while a short five question worksheet due in three days may be labeled a “C”.  Make sure you don't wait until the last second to get assignments done.
A: Get your supplies in order. Make a homework plan for the evening. Start your homework soon after you get home from school. Prioritize by due date and importance.

Problem: Article: After 2 weeks, pick out any seedlings that are growing near the edge of a cell or have grown crooked and sideways. Leave about 5 seedlings in each cell so they will not be overcrowded as they continue to grow. After the seedlings grow 6 to 8 inches (15 to 20 cm), their roots will be too crowded to stay in the cell tray. Pre-moisten the potting soil in a 2 gallons (7.6 L) pot and make an indentation with your finger equal to the size of one of the cells. Squeeze the bottom of the cell tray to push out the root ball of the tobacco and place it in the indent you’ve made.  Separate the cells from the tray by cutting them individually with a pair of scissors. If the tobacco plant starts to droop or wilts to one side, use a wooden barbecue skewer to support it upright. Find a fertilizer at your local gardening store that does not contain chlorine and provides nitrogen to your plant in the form of nitrate. Since tobacco is in the same family as tomatoes and peppers, fertilizers manufactured for their use will work just as well. Follow the directions on the package to determine how much fertilizer to use. Do not apply any fertilizer after flowers begin to form. The more sunlight your plant gets, the larger it will grow. Tobacco plants need full sun throughout the day, so keep them near a large window. If the weather does not drop below freezing, you can also keep them outside during the day and return them inside at night. You can also use grow lights to provide enough light for the plant as well as additional warmth. As tobacco grows, it will require more water. Check the soil daily and keep it moist with a watering can. Don’t allow the water to puddle on the surface. Excessive water will promote diseases like bed rot or mildew to form in the roots. Once a flower forms and blooms, the tobacco will stop growing for the season and reduce your total yield. To keep your plant growing, use a pair of pruning shears to cut off the flowers before they blossom.
Summary:
Pluck out half the sprouts from the cell tray with tweezers. Transplant seedlings into pots when they are 6 to 8 inches (15 to 20 cm) tall. Apply a fertilizer with nitrate and no chlorine. Keep tobacco in an area with 6 hours of sunlight. Water the tobacco so the soil is wet, but not drenched. Cut off flowers as they begin to form.
