Q: To grow mold on bread you will need to collect the following materials: a slice of bread (any kind), a sealable plastic bag, a spray bottle, and water. You can use any type of bread, but know that store-bought sandwich bread contains preservatives and will take longer to grow mold. Fresh bread will grow mold faster. A spray bottle is not entirely necessary, but it is an easy way to evenly coat the bread in a fine mist of water. Fill the spray bottle with water before beginning the experiment. If you don't have a plastic bag, you can replace it with some other sealable clear container. You want it to be clear so you can observe the mold growth and sealable to contain the mold. An old plastic or glass jar would also work, but you'll need to throw it away at the end of the experiment. Using the spray bottle, lightly spray the piece of bread with a coat of mist. You don't want the bread to be soaked, you just want there to be some moisture to stimulate the growth of the mold. One spray is sufficient. Alternative methods for keeping the environment moist include: Placing a wet paper towel in the plastic bag with the bread. Sprinkling some water over the top of the piece of bread. Spraying the inside of the bag instead of directly on the bread. Place your moistened piece of bread into the plastic bag and seal it closed. For the remainder of the experiment you'll want to keep this bag sealed to avoid exposing yourself to the mold spores that will grow on the bread. If you have allergies, you might not want to do this experiment as it may cause you difficulty. Mold thrives in warm environments with moisture in the air. Find a warm place in your home and store the sealed bread here. You've already supplied sufficient moisture to the bread for growth. Mold is a heterotroph, so it does not need sunlight to create food. It gets food from the bread itself in the form of starch which is broken down into smaller sugars. This is why mold often grows in dark, damp areas such as basements. Make daily observations of your bread and track the growth of mold. It should take around 7-10 days before you will be able to see significant growth on the bread. You could see growth as soon as 5 days depending on the type of bread you used. Remember, fresh bread will mold faster than store-bought bread containing preservatives. If you notice the bread has dried out, start over with a wetter piece of bread instead of adding water to the bread. Mold spores can cause allergic reactions and respiratory problems. Some mold contains mycotoxins which can cause neurological problems or even death. When you are finished observing the growth of the mold, dispose of the sealed container in the garbage. Do not open the bag. Opening the bag can release mold spores into your environment that are not good for your health. Wash your hands every time after you have handled the bag.
A: Gather the necessary materials. Spray the bread with water. Seal the bread in the plastic bag. Store the bread in a damp, warm area. Observe the mold growth. Dispose of the bread properly.

Q: Gaiters usually come in either an ankle or full length style. Ankle gaiters will cover your shoe and the bottom of your pants. They are usually best for keeping grit and debris out of your shoes. Full length gaiters are the most common. They keep snow, water, and debris out of your shoes and protect you from things like thorns and snake bites. Ankle gaiters are good for off road and fell runners because they are closer fitting than full length gaiters and protect you from water ingress. Gaiters come in many sizes. Usually, you will need a pair of gaiters that correspond with your shoe size. Along with shoe size, they should also fit snugly around your calf. If possible, it's best to try on gaiters at a store to make sure they fit you properly. The cheapest gaiters will usually come with Velcro as a fastener. A majority of gaiters have lace hooks that can adjusted to fit your leg and shoe. Higher end gaiters often have waterproof zips or click-lock buckles. Costly brands are usually more reliable, but you don't have to buy the most expensive brand of gaiters to get the protection you need.
A: Decide on a length. Select a size that corresponds to your shoe size. Choose a fastening method.

Q: Consider all consecutive integers. Determine the number of terms (n{\displaystyle n}) in the sequence. Since you are considering all consecutive integers to 500, n=500{\displaystyle n=500}. Determine the first (a1{\displaystyle a_{1}}) and last (an{\displaystyle a_{n}}) terms in the sequence. Since the sequence is 1 to 500, a1=1{\displaystyle a_{1}=1} and an=500{\displaystyle a_{n}=500}. Find the average of a1{\displaystyle a_{1}} and an{\displaystyle a_{n}}: 1+5002=250.5{\displaystyle {
rac {1+500}{2}}=250.5}. Multiply the average by n{\displaystyle n}: 250.5500=125,250{\displaystyle 250.5 imes 500=125,250}. The first term in the sequence is 3. The last term in the sequence is 24. The common difference is 7. Determine the number of terms (n{\displaystyle n}) in the sequence. Since you begin with 3, end with 24, and go up by 7 each time, the series is 3, 10, 17, 24. (The common difference is the difference between each term in the sequence.) This means that n=4{\displaystyle n=4} Determine the first (a1{\displaystyle a_{1}}) and last (an{\displaystyle a_{n}}) terms in the sequence. Since the sequence is 3 to 24, a1=3{\displaystyle a_{1}=3} and an=24{\displaystyle a_{n}=24}. Find the average of a1{\displaystyle a_{1}} and an{\displaystyle a_{n}}: 3+242=13.5{\displaystyle {
rac {3+24}{2}}=13.5}. Multiply the average by n{\displaystyle n}: 13.54=54{\displaystyle 13.5 imes 4=54}. Mara saves 5 dollars the first week of the year. For the rest of the year, she increases her weekly savings by 5 dollars every week. How much money does Mara save by the end of the year? Determine the number of terms (n{\displaystyle n}) in the sequence. Since Mara save for 52 weeks (1 year), n=52{\displaystyle n=52}. Determine the first (a1{\displaystyle a_{1}}) and last (an{\displaystyle a_{n}}) terms in the sequence. The first amount she saves is 5 dollars, so a1=5{\displaystyle a_{1}=5}. To find out the amount she saves the last week of the year, calculate 552=260{\displaystyle 5 imes 52=260}. So an=260{\displaystyle a_{n}=260}. Find the average of a1{\displaystyle a_{1}} and an{\displaystyle a_{n}}: 5+2602=132.5{\displaystyle {
rac {5+260}{2}}=132.5}. Multiply the average by n{\displaystyle n}: 132.552=6,890{\displaystyle 132.5 imes 52=6,890}. So she saves $6,890 by the end of the year.
