Q: Vegetables are an important food group to prevent a variety of diseases and cancers. However, red, yellow and orange vegetables have high levels of vitamins and antioxidants that can help keep your colon healthy. What makes these vegetables that particular color are the vitamins and antioxidants that are found in them. Red, yellow and orange vegetables are particularly high in an antioxidant known as beta carotene which is an orange/red color. This antioxidant is often associated with Vitamin A as it is a precursor to becoming Vitamin A in your body. Adequate intakes are also associated with a decreased rate of colon cancer. Include a one cup serving of any of these colored vegetables. You can try: red, yellow and orange bell peppers, sweet potatoes, pumpkin, butternut squash and carrots. Another group of foods that can help protect your colon and resist the formation of polyps are folate-rich foods. Luckily, folate can be found in a wide variety of foods. Studies have shown that an intake of 400 IU of folate every day can help prevent the formation of polyps but also helps prevent colon cancer as well. 400 IU of folate is easily consumed if you eat a balanced diet and focus on folate-rich foods. Specific foods that are high in folate include: fortified breakfast cereals, spinach, black-eyed peas, asparagus, broccoli, green peas, whole wheat bread and peanuts. Calcium is another commonly found mineral that has been shown to prevent the formation of colon polyps. Including regular servings of foods high in calcium can help protect your colon. One study in particular showed that those people who consumed 1200 mg of calcium daily (which you can get from three servings of calcium-rich foods), had a 20% less recurrence of cancerous colon polyps. Calcium is found most commonly in dairy foods. You can have milk, yogurt, kefir, cheese or cottage cheese to get in an adequate serving of calcium. In addition, calcium is found in other plant-based foods outside of the dairy group. Almonds, broccoli, dark greens, and fortified orange juice or soy milk offer another source of calcium. Some foods contain a certain type of fat called omega-3 fats. Often known as heart healthy fats, these fats are also beneficial to your colon. Studies have shown that omega-3 fats help maintain and even improve cell health in the colon. Include regular servings of healthy fats to help prevent colon polyps. Healthy fats are found in a wide variety of foods. Include a serving of these foods daily to help protect your colon and prevent the formation of polyps. Include foods like: avocado, olive oil, olives, salmon, tuna, sardines, mackerel, walnuts and flaxseeds. Many studies have shown the benefits of green tea in preventing polyps and colon cancer. Try swapping out your morning coffee for a cup of green tea or drink a cup or two of decaffeinated green tea after dinner. Although water is not a specific food or a nutrient, it's essential to overall health. Specifically, studies have shown that a lack of adequate water can lead to dehydration and polyp formation in your colon. When you don't drink adequate amounts of fluids, your body will harvest free water from other areas - like your stool or other cells. This causes dehydration and constipation. Decreased bowel transit time and the concentration of carcinogenic compounds that are found in cells can increase your risk for the growth of cancerous polyps. Health professionals recommend drinking about 64 oz or 8 glasses of water everyday. However, you may need to increase your water intake to prevent constipation.
A: Focus on red, yellow and orange vegetables. Include folate-rich foods. Consume calcium-rich foods. Focus on healthy fats. Drink green tea. Drink more water.

Q: If you want to describe a current state of being that is in doubt or is hoped for, you would use the present subjunctive. This tense is used far more often in Spanish than it is in English. While a literal translation is "to be," in this tense and mood it means more like "may be." For example, you might say, "Dudo que ella sea rica" to mean "I doubt that she is rich." Yo sea: I am/may be. Tu seas: You are/may be. El/ella/usted sea: He/she/you are/may be. Nosotros/-as seamos: We are/may be. Vosotros/-as seais: You all are/may be. Ellos/ellas/ustedes sean: They/you all are/may be. Just as with the perfect tenses in the indicative mood, you form past, present, and future subjunctive tenses with the helping verb haber. To form present perfect subjunctive (in Spanish know as preterito pluscuamperfecto/antepreterito), use the present subjunctive of haber along with sido. Use this tense to describe a state of being in the past that is connected to one in the present, or will have happened at some point in the future. For example, you might say, "Dudo que hubiera sido rica" to mean "I doubt that she has been rich." The past perfect subjunctive is used for hypothetical or conditional states of being in the past. Use the imperfect subjunctive (in Spanish know as preterito perfecto compuesto/antepresente) conjugation form for haber along with sido. For example, you might say, "Haya sido rico," or "I have been rich." The future perfect subjunctive (in Spanish know as futuro compuesto/antefuturo) form of ser is used to talk about a state of being that will have been in existence in the future, or might have or could have existed in the future. Combine the simple future conjugation form of haber with the past participle sido. For example, you might say, "Yo habre sido rico," to mean "I will have been rich."
A: Start with present subjunctive. Combine the correct conjugated form of haber with "sido" for perfect subjunctive tenses.

Q: The polarity of batteries is what helps them supply current to a device. The plus sign, or +, indicates the positive terminal. On AA, AAA, C, and D batteries, the positive end should be slightly raised. The negative end of the battery should be flat, and it may or may not be marked with a minus, or -, symbol. There should be a plus and minus sign inside the battery compartment. This will tell you which direction the battery needs to go. The negative end may have a spring or a small metal lever. If the polarity isn't marked on your device, you may need to consult the manufacturer's instructions. It's very important to make sure that each battery is properly aligned inside the device. If your battery faces the wrong way, it could cause your device to malfunction, or it could even cause the batteries to leak dangerous corrosive chemicals. The plus sign on the battery should match the plus sign on the device. As you insert the negative end of the battery, you may press down a spring or a lever. By installing the negative end first, the battery will slide into the compartment more easily. You should then be able to easily snap the positive end into place. The positive end of the battery should snap into place with a gentle push. If you have multiple batteries side-by-side, they may alternate directions. This creates a series of current that amplifies the energy produced by the batteries. Make sure each battery faces the direction that's indicated in the battery compartment or the user manual. Some devices that use multiple batteries may continue to function if one battery is installed incorrectly, but you can damage the device or shorten the life of the batteries by doing so.
A:
Look for a plus symbol on your battery. Find the positive and negative symbols on your device. Align the symbols on the battery with those on your device. Slide the battery into place with the negative end first. Check the alignment of every battery.
