Answer:
A site
Explanation:
During the process of translation, ribosomes play a major role in connecting mRNA codons with tRNA anticodons. Ribosomes are composed of  two subunits which consist ofproteins and rRNA. The tree sites of ribosomes are:
- P site or peptidyl site-this site binds to the tRNA which holds the growing polypeptide chain.
- A site or acceptor site-this is a site of peptide bond formation between the growing polypeptide and the next incoming amino acid
- E site or exit site-the site for the final binding of t-RNA .
 
        
             
        
        
        
Answer:
A
Explanation:
Coal is majorly used to produces electricity. The coal is ignited and the heat produced used to heat water to steam. The steam is then used to drive turbines with a dynamo effect to produce electricity. Turning off lights when not in use reduces the demand for electricity hence reducing the amount of coal needed to meet this demand. 
Other ways to conserve energy is using bulbs with low energy demand - such as LEDs - and  improving natural lighting indoors. 
 
        
             
        
        
        
Answer:
large grain sizes, more precipitation, warmer temperatures.
Explanation:
Soil is the thin layer of material covering the earth's surface and they are usually formed through the process of weathering of rocks. The soil consists of mainly mineral particles, organic materials, air, water and living organisms and they interact with each other.
Large grain sizes, more precipitation, warmer temperatures are the factors that increase the rate of soil formation.
