Q: You can use your indicator by placing drops of various liquids into it. Indicators turn colorless when exposed to vitamin C. Therefore, you only need a small volume of liquid with a high level of vitamin C to cause the indicator to lose color. You need a larger volume of liquid with a low level of vitamin C to change the indicator's color. If you want to test various liquids, put a bit of the indicator in a few different test tubes. You will be adding drops of different liquids to each test tube. You do not need a lot of indicator to start with, but make sure the amounts are consistent from test tube to test tube. For example, if you put 5 drops of indicator in the first test tube, you should put 5 drops in all other test tubes. Assemble a variety of liquids to test. Use your eye dropper to add 10 drops of each liquid to each test tube of indicator. Then, see how much the color has changed in each tube. Make sure to wash your eyedropper each time you measure out a new liquid. You do not want to accidentally mix liquids, as this will cause inaccurate results. Liquids with a high concentration of vitamin C will have changed the indicator to a light, possibly clear shade. For liquids with a low concentration of vitamin C, the indicator will be darker, retaining a lot of its purple-blue shade. Some test tubes may be very similar in color. If you're struggling to see which is lighter and which is darker, hold the test tube up against a white background like a wall or a piece of paper. If you only have one test tube, there is another way to compare and contrast vitamin C levels. Using one liquid at a time, record how many drops of each liquid it takes to cause the indicator to change color. The lower the number of drops, the higher the concentration of vitamin C in a substance.
A: Prepare your indicator for use. Add 10 drops of various juices to each test tube. Measure the samples from lightest to darkest. Count how many drops it takes for a sample to change color.

Q: Communication is perhaps the most important leadership quality, and one that runs through all of the other important qualities. One of the keys to good communication is enabling positive and sometimes robust dialogue on problems and solutions. There are different styles of leadership, but someone who consistently shuts down debates and stifles discussions is unlikely to command the support of others for too long. Ask and encourage open questions, rather than constrictive ones. Highlight areas of agreement first, and deal with the disagreements second. Don't be overbearing, and facilitate an open environment where people are free to talk without fear. Positive body language can help you come across as dynamic, open and cooperative. It can also help you to make a strong impression when you are talking, and increase the power and effectiveness of your words. One good rule is to have body language that is consistent with what you are saying. Don't, for example, ask someone to do something while looking down at the floor. Instead make eye contact and be open and engaging. To have positive and affirmative body language while talking, try to maintain eye contact, stand tall and straight, and relax your face. Your body language may be interpreted as how you are really feeling, so try to have body language that reflects the qualities and approach of a good leader. To be a good communicator, you need to be a good listener. If you make the effort to listen to somebody, she will see that and come to think of you as someone she can talk to. This is an important leadership quality to develop. Body language is important, so try to maintain eye contact with the person you are talking to. To be an active listener: Don't judge people. Pay complete attention to the person you are talking to. Try to understand others, before you try make yourself understood. Don't interrupt unnecessarily.
A: Enable effective dialogue. Have positive body language. Be an active listener.

Q: Physical therapy (PT) may be prescribed by a physician for long-standing neck and back pain secondary to spondylosis. PT may combine passive treatments, such as ice and heat, ultrasound, and electrical stimulation, with therapeutic exercises to stretch and strengthen neck, abdominal, and back muscles. Physical therapy is usually prescribed for chronic pain that has lasted for several weeks without responding to other treatments. Massage therapy may also be introduced into your physical therapy routine. A professional massage therapist will work on the muscles in your back to soothe and relax them after you have exerted them. The goal of PT is to prevent recurring pain. Spinal manipulation performed by a chiropractor may also help relieve the pain of spondylosis, especially with the first month of pain. It works by realigning vertebrae, which have been misaligned due to weakness in the spine brought on by spondylosis. Overall, it is a safe procedure. The most common side effects are generally minor and include fatigue and temporary muscle soreness. Extremely rare complications of spinal manipulation may include weakness, loss of feeling in legs or arms, and bowel or bladder problems. Acupuncture is a popular treatment for long-standing neck and back pain. Acupuncture for spondylosis involves inserting very thin needles, about the size of a human hair, into the neck or back. The needles can be twirled, electrically stimulated, or warmed to augment the results of treatment. It is thought that acupuncture balances the chi of the body, which flows in meridians. An alternative explanation may be that acupuncture causes the release of chemicals that reduce pain and inflammation.
A:
Undergo physical therapy. Try spinal manipulation. Consider acupuncture.
