Problem: Write an article based on this summary: Pick a variety of colors.

Answer: It will look a lot like an older, more healed bruise if you use a regular pencil, but you can use a variety of colors if you want to make it more exciting. Use regular gray pencil lead, as well as dark blue and purple for your bruise.

Problem: Write an article based on this summary: Use a biological filter. Add barley straw to your pond. Add plants to the pond.

Answer: A biological filter uses bacteria to remove organic waste that can accumulate in your pond. You could get an in-pond filter or an external filter. In-pond filters have a pump attached to a fountain that runs into the pond. While they are easy to setup and install, they are difficult to clean because you must remove the entire contraption from the pond. External filters are very easy to clean, but it can be difficult to get the right size and pump, since they are usually designed for pools, not ponds. While these bacteria occur naturally in ponds, they are not present in the quantities necessary to adequately filter all the toxins that occur in most ponds. Get a filter capable of filtering about twice the amount of water that our pond contains. For instance, if a filter says it can adequately filter 3,000 liters, you should use it only if your pond is around 1,500 liters or less. If you get a filter that matches your pond's volume exactly, it will struggle to keep the pond clean. Your filter should filter your entire pond in about two hours. Check the speed of the pump and compare it to your pond's volume to choose the right one. As barley straw decomposes, it releases a chemical that prevents algae from growing. One bale of barley straw treats 1,000 gallons of water. In other words, if your pond holds 100 gallons, you'd need only one-tenth of a bale. The best way to add the straw is to wrap a softball-sized portion of straw in mesh netting and toss the balled-up straw in the pond. Alternatively, you could add liquid barley straw. One tablespoon usually treats about 50 gallons. If you don't notice a change after about a week, add more gradually. Barley straw is readily available at most garden centers. Barley straw is safe for use in ponds with fish. You could add both floating plants and submerged plants to your pond. Both will keep algae at bay and keep your pond clean in a natural way. Add floating plants. Lilies and lotus reduce the total surface area of the pond that algae can thrive on, and absorb nutrients that algae would otherwise use to grow. Submerged plants like hornwort, parrot's feather, and anacharis add oxygen to the water, preventing algae. They can be kept below the water's surface by attaching them to a rock or putting them in a plant pot and adding weight until it sinks.

Doing so opens the Device Management service. You may have to scroll down to view this feature. This microchip-shaped icon is at the bottom of the screen. At the top of the screen, you'll see a circle with the RAM that's being used over the total installed RAM (e.g., "1.7 GB / 4 GB"). You can also view a breakdown of how your Android's RAM is being used below this circle by looking at the "System and apps" heading, the "Available space" heading, and the "Reserved" heading.

Problem: Write an article based on this summary: Feed your cat a healthy diet. Serve your cat high-quality foods. Change your cat's foods when needed. Contact your veterinarian if your cat's coat seems inexplicably dull.

Answer:
To have a healthy coat, a cat must eat a healthy diet. Whether your cat eats canned food, dry food, raw food, or a combination of these, its diet should be high in proteins and fats. Your cat should also always have plenty of clean, fresh water to drink. Talk to your veterinarian for specific advice about selecting the right foods for your particular cat. Commercial cat foods can vary in quality. To ensure that your cat's coat stays healthy-looking, check the food's nutritional content (listed on the label) and make sure it matches your cat's current needs. To ensure quality, you can look for a cat food with a label showing that it has been certified by the Association of American Feed Control Officials (AAFCO). Raw meat diets are recommended by some experts as a way of making it easy for a cat to get the nutrients it needs. Your cat's dietary needs will vary throughout its lifetime; foods that are designed for kittens are not suitable for older cats, and vice versa. The nutrition your cat needs also depends on its individual factors, like health and activity level. If your cat is not receiving the right kind of food for its age and activity level, its coat may look coarse and dull. If you are feeding and grooming your cat according to its needs, and its coat still seems dull, brittle, or coarse, talk to your veterinarian about the problem. Health problems, such as digestive issues, parasites, cancer, obesity, or stress can affect the appearance of your cat's fur. Your veterinarian can determine if there is an underlying health problem causing the poor coat quality.
