Answer:
The correct answer is "Shine Dalgarno sequence".
Explanation:
- A consensus originally characterized throughout the mRNAs to Escherichia coli seems to be the Shine-Dalgarno chain.  
- Proteins manufactured through sequences comprising unique sequences became generated more gradually or slowly than similar proteins encoded of separate but interchangeable codons from genes, researchers observed.
 
        
             
        
        
        
Respuesta: Energía eólica. 
Explicación: La energía eólica o las cosas que utilizan energía eólica, como las turbinas eólicas, no liberan emisiones que puedan contaminar el aire o el agua. Por tanto, una fuente de energía no contaminante. 
Espero que esto ayude, buena suerte! :)
 
        
             
        
        
        
Your answers would be:
1. ---- B. A cell cannot be subdivided into smaller units that maintain the living state.
2. ---- The organism is a eukaryote because it has a nucleus. 
3. ---- D. Water would flow into them because they are hypertonic to external environment. 
If you want to know why:
1. The cell is the basic unit of life or in other words, its the smallest unit that makes up a living thing. It does not subdivided further if you are talking about sustaining life. Yes, it is made up of smaller units of organelles, but these organelles work together as a single unit (as a cell), to do life sustaining processes.
2. The organism is a eukaryote because of the presence of a nucleus. This is one of the main features of a eukaryote that differentiates it from a prokaryote. Prokaryotes to not have a true nucleus. 
3. Water would flow into them, causing the cell to swell and eventually burst if the concentration of solutes would not even out before then. The process of osmosis is what brings the water into the cell. The cell would have a higher solute concentration than freshwater. Through osmosis, the water would then go to the area of higher concentration, which would be the cell.
