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.
Materials for Life. Carbon, hydrogen, oxygen, nitrogen, phosphorus, and calcium form the major chemical scaffolding of biological molecules. Hydrogen, nitrogen, oxygen, phosphorus, and sulfur combined with carbon generated the first group of compounds that eventually formed the chemical basis of life.arbon The carbon compounds that make up essential molecules such as proteins are described in the notes on biological molecules. Carbon is second only to hydrogen in the number of compounds it can form, oxygen being the third in this capability. Carbon can form more than 2500 compounds with hydrogen alone.
