If bleeding is severe, or if you think there is internal bleeding, or the person is in shock, get emergency help. 1  Calm and reassure the person. The sight of blood can be very frightening.  If the wound affects just the top layers of skin (superficial), wash it with soap and warm water and pat dry.
Carbon is Important to Life. In its metabolism of food and respiration, an animal consumes glucose (C6H12O6), which combines with oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy, which is given off as heat. The animal has no need for the carbon dioxide and releases it into the atmosphere. A plant, on the other hand, uses the opposite reaction of an animal through photosynthesis. It intakes carbon dioxide, water, and energy from sunlight to make its own glucose and oxygen gas.
