Changing the length of the instrument is the easiest method to change the frequency.
        
             
        
        
        
Cell division. The whole process involves 3 main stages namely interphase, mitosis and cytokinesis.It would, however be wrong to say that its mitosis only because mitosis does not involve the duplication of chromosomes. Duplication of chromosomes occur during the interphase while the splitting of cells occur during Telophase of mitosis and Cytokinesis. Therefore, answer to this has to be generalised to be just cell division.

Cellular respiration in algae, as in all organisms, is the process by which food molecules are metabolized to obtain chemical energy for the cell. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.<span>
