B. Is correct because in mutualism both species benefit. It could be symbiosis but mutualism is more specific.
Cellular respiration is the process of oxidizing organic molecules such as glucose to form carbondioxide and water.The energy released during this process is stored in the form of ATP molecules which is further used for all energy consuming activities of cell. So the answer is A.
Answer:
Scanning electro microscopy
Explanation:
"A scanning electron microscope (SEM) scans a focused electron beam over a surface to create an image. The electrons in the beam interact with the sample, producing various signals that can be used to obtain information about the surface topography and composition"
