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.
So life is really chemistry. Life really is a form of chemistry, a particular form in which the chemicals can lead to their own reproduction. But the important thing, I think, is that when we think about the origin of life this way, it isn't that life is somehow different from the rest of the planet.Life is something that emerges on a developing planetary surface as part and parcel of the chemistry of that surface.ndy Knoll: It's fair to say when you go out and walk in the woods or on a beach, the most conspicuous forms of life you will see are plants and animals, and certainly there's a huge diversity of those types of organisms, perhaps 10 million animal species and several hundred thousand plant species.
