In one sentence, describe what the following article is about: This method may be tedious when making more than a few tostada shells. The paper towels soak up moisture and create a crunchy texture. Do not allow the edges of the tortillas to overlap. Microwave on high for 1 minute. Turn the tortillas over and place fresh paper towels on top. Microwave on high for 1 additional minute. You may wish to microwave tostada toppings after you have baked or fried the shells.
Summary: You can also make crispy but oil-free and extremely low-fat tostada shells in the microwave. Place 2 layers of paper towels on your microwave's cooking carousel. Layer several tortillas onto the carousel, directly onto the paper towels. Cover the tortillas with an additional layer of paper towels. Open the microwave and remove the top layer of paper towels. Optional: Finished.

In one sentence, describe what the following article is about: You cannot introduce lovebirds unless you know that both animals are healthy. Take the pair to the vet to make sure that they’re healthy enough to breed.  Let your vet know that you plan to breed the lovebirds. Ask her any questions you might have about the birds, their health, or breeding the pair. If you bring a new lovebird into your flock for mating, consider quarantining the pair for a few days. This can help ensure that both are healthy and that the female doesn’t get territorial or reject the male. If you are breeding lovebirds you already own, you likely don’t need to quarantine the pair When you know that each lovebird is healthy, introduce the pair. Take it slowly, as it could take a few days for the birds to get used to one another.  Place the birds in cages next to one another before putting them in the same cage. Move the birds to the same cage after a couple of days. Put nesting materials in the cage to encourage the couple to start building a nest.  Remove any birds that are exhibiting signs of aggression or rejection of a potential partner. Lovebirds are prolific reproducers and you may notice many signs of mating. Signs of mating can include:  Courtship Aggression Jealousy or being “hormonal”  Carrying material in the feathers Nest-building. Lovebirds that are breeding need dense, nutrition packed foods because of the stress on their bodies. Avoid giving them just seeds, which may not provide enough nutrients for the birds or their babies. Some examples of what you can mix together to feed your lovebirds are:  Cooked elbow macaroni Pearl barley Frozen vegetables Granulated sea kelp Whole grain brown rice Apples Greens Cereal, toast or crackers Cuttlebone. The only way to be certain that your lovebirds have mated is by checking for eggs. In most cases, the female lovebird will lay her first egg ten days after mating and then will brood, or sit on the eggs, after the second is laid.  Look at the nest every morning to see if there are any eggs. The female will generally lay eggs at night. She may produce one egg every other day, up to 5 or 6 eggs.  Be aware that two female lovebirds, if placed together. can lay up to 10 infertile eggs. It takes around 25 days for a female to brood, or sit on, her eggs. Let her brood uninterrupted for at least 10 days. Be aware the female will only leave to excrete waste, drink, and have a bite of food. In most cases, the male will feed the female during brooding. It’s common to have infertile eggs, especially if a pair is too young or old. After allowing the female to brood for 10 days, you can check to see if the eggs are fertile.  Handle the eggs as gently as possible.  Check each egg by holding an egg up to a light source, such as a flashlight and looking for a membrane, which is a sign the egg is fertile.  You can also check by placing the egg in a shallow dish of warm water one week before it hatches. After five seconds, check if you can see a membrane.  Be aware that it is normal for eggs to not be fertile or for a baby to die in the egg. After between 21-26 days of brooding, your eggs may hatch. Be sure to not handle the eggs or the hatchlings for the first 6-8 weeks of life.  The mother bird will feed the babies for 6-8 weeks from the nutritious food you provide.  Remove any unhatched eggs or baby lovebirds that die.
Summary: Check the health of your lovebirds. Consider quarantining the animals. Introduce the lovebird pair. Watch for signs of mating. Provide the birds enough nutrition. Check for eggs. Allow the female to brood. Figure out if eggs are fertile. Wait for the eggs to hatch.

In one sentence, describe what the following article is about: Molarity is equal to the number of moles of a solute divided by the volume of the solution in liters. As such, it is written as: molarity = moles of solute / liters of solution Example problem: What is the molarity of a solution containing 0.75 mol NaCl in 4.2 liters? Finding molarity demands that you have the number of moles and the number of liters. If the problem provides each of these figures, no preliminary calculations are needed. Example problem:  Moles = 0.75 mol NaCl Volume = 4.2 L The resulting quotient will give you the number of moles per liter of solution, otherwise known as molarity. Example problem: molarity = moles of solute / liters of solution = 0.75 mol / 4.2 L = 0.17857142 Round off the number of digits after the decimal point to two or three, depending on your instructor's preference. When you write out the answer, abbreviate "molarity" with "M" and state the chemical abbreviation of the solute involved. Example problem: 0.179 M NaCl
Summary:
Know the basic formula for calculating molarity. Examine the problem. Divide the number of moles by the number of liters. Write your answer.
