Disabilities make life in school, and among peers more difficult.
Answer:
Even though the symptoms of the stimulants and depressants are quite opposite, the causes of these symptoms are completely unrelated. A stimulant could cause one area of the brain to release a chemical and a depressant could affect a completely different area of the brain. They don't have to counteract each other.
Explanation:
2. When the left ventricle relaxes, the aortic valve closes and the mitral valve opens. This lets blood flow from the left atrium into the left ventricle.
4. Quickly shocking the heart with an automated external defibrillator (AED) can save a person's life after cardiac arrest. An AED is a portable, battery-operated device that a bystander can use. It checks the heart rhythm and can send an electric shock to the heart to try to restore a normal rhythm.
5. High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause: Chest pain, also called angina.
hope this helps :)
C because my teacher gave me the answers
n the UK, up to one third of people with cancer (33%) use some sort of complementary therapy at some time during their illness. For some types of cancer, such as breast cancer, the number of people using complementary therapies is even higher at almost half (50%).
There is no evidence to suggest that any type of complementary therapy prevents or cures cancer. But people are very interested in using complementary therapies for many reasons, including those mentioned on this page.
For some therapies there is currently very little research evidence to show that they help with certain symptoms – for example, pain or hot flushes. But reliable research studies are being carried out and we are beginning to collect evidence for some types of therapy. For example, there is evidence of improved quality of life following mindfulness based stress reduction, and reduced chemotherapy related nausea in people who have acupuncture.
Even where there is little or no evidence for some types of complementary therapy, many people with cancer say they gain a lot of benefit from using them.
