Answer:
La biomasa (energía) se refiere a la biomasa «útil» en términos energéticos formales: las plantas transforman la energía radiante del Sol en energía química a través de la fotosíntesis, y parte de esa energía química queda almacenada en forma de materia orgánica; la energía química de la biomasa puede recuperarse quemándola directamente o transformándola en combustible.

There's a shrink to the upward thrust of a sand dune. they do no longer stay interior a similar place yet crawl downwind and are replaced by capacity of latest ones. at last, they attain the factor the place they'd be stabilized by capacity of plant existence. Barrier islands are formed a similar way, different than by capacity of water, somewhat than wind.
        
                    
             
        
        
        
The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane. 
Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy. 
Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels. 
Both facilitated diffusion and active transport requires the proteins present in the cell membrane. 
 
        
             
        
        
        
It is false that cytoplasm is a single substance like water.
It consists of 80% water, but has other elements as well.
