Answer: 16 mm
Explanation:
If I understood the given equation correctly, it could be rewritten as:
size of image = size of real object * magnification
Plug in the given values, and we get 
size of image = 0.8 * 20 = 16 (mm)
 
        
             
        
        
        
Answer:
1.2The main processes involved in the movement of water between the different reservoirs are evaporation, condensation, transport, precipitation, runoff (water runoff from the ground surface), infiltration and transpiration
3.The large surface of the oceans (about 70 percent of the earth's surface is covered by oceans) favors the occurrence of large-scale evaporation. On a global scale, the same amount of water that is evaporated returns to Earth as precipitation. This however varies geographically
4.Earth from Space Although the engine of the cycle is the solar energy that originates the evaporation of liquid water, and therefore its passage into the atmosphere, the role of gravity is also fundamental, thanks to which precipitation falls and continental waters return to the oceans
5.The water cycle is powered by solar energy. The sun heats the surface of the ocean and other surface waters, which evaporates liquid water and sublimates ice, converting it directly from a solid to a gas. These sun-driven processes move water into the atmosphere in the form of water vapor

Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. Like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and cell lysis. Antimicrobilas that act by inhibiting cell wall synthesis include beta-lactams, vancomycin and cycloserine and isoniazid and ethambutol among others. They prevent bacteria from increasing amount of peptidoglycan, they have no effect on existing peptodoglycan layer and therefore are effective only for growing cells.
        
             
        
        
        
Answer;
-Proteins play a role in transport, enable movement, provide structure and support, and help make chemical reactions happen.
-Nucleic acids carry genetic information, determine the structure of proteins, and help build proteins.
Explanation;
-Biological macromolecules are the large molecules necessary for life, include carbohydrates, lipids, nucleic acids, and proteins.
-Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. 
 
        
                    
             
        
        
        
Answer:
polymer any of a class of natural or synthetic substance composed of very large molecules called macromolecules,that are multiple of simpler chemical units called monomers .polymers they make up many of the materials in living organisms example proteins , cellulose
