Answer:
B. Ribosome
Explanation:
Ribosomes are the organelles that serve as a site for protein synthesis. Each ribosome has two subunits. The small subunit first joins with mRNA and the initiator tRNA to start the process of protein synthesis. The large subunit joins the complex and the proteins are synthesized according to the nucleotide sequence of the mRNA read in the form of genetic triplets. Ribosomes are present in cytosol as well as on the surface of the rough endoplasmic reticulum of a eukaryotic cell. In both locations, they are involved in the process of protein synthesis.
Convection : Warm air rises and cold air sinks, you have a cycle there :D
You can experience it on the beach shore. Since water has a high heat capacity ( it takes longer to heat up ) and the sand get hot quickly, the air on the shore gets warm and rises. When the air reaches to certain elevation (or meet the temperature of the beach), it gets cooler and sinks, cold air from the beach blown to the shore.
