The process by which a cell divides is called mitosis. It results in two daughter cells that are genetically identical to each other and to the original cell.
Multicellular organisms,  depend on mitosis for growth and repair. Organisms repair some of their tissues  using mitosis to regenerate new cells. Not all cells undergo mitosis at the same rate. In man, brain cells are much more difficult to regenerate than cheek cells which are constantly being replaced.
 
        
             
        
        
        
First question is - Why do we have limestone? Formed from this type of sediment are biological sedimentary rocks. Their biological organ is often revealed in the rock fossils. Some limestones can form by direct precipitation of calcium carbonate from marine or fresh water. (The second question is) - What do iron bands mean? The rocks are "banded" because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity steel mill. Most iron ore is used to make steel. Here a steel slab is being cut to length in a steel mill.
        
             
        
        
        
Answer:
One of the major goals of environmental science is to understand and to solve environmental problems. In order to accomplish this goal, scientists study two main types of interactions between humans and their environment. One area of focus is on how we use natural resources, such as water and plants.
Explanation:
Environmental science is important because it enables you to understand how these relationships work. For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.
