Answer : B) In step 2, there was a chemical change which was observed in sugar.
Explanation : In A step 2 there was a physical change that was seen. By just boiling the dissolved salt solution salt was obtained. Therefore, it is a physical change. In B step 2 there was a chemical change seen as sugar solution was thickened and turned brown. It was not obtained in its original form; there was a chemical reaction that took place during sugar evaporation. As chemical change is the one where the reaction is irreversible.
Therefore only in B step 2 there was a chemical change that was observed.

Explanation:
The ribosome has two subunits; a smaller one and a bigger one. The smaller one contains 21 proteins and one rRNA molecule, and the larger subunit contains 34 proteins and two rRNA molecules. Ribosomes are found in prokaryotes and eukaryotes (although they are a little different, they have the same function). Ribosomes are made of nucleolus. Some people might think that mRNA also helps to form the structure of the ribosome, but this is not the case. rRNA makes up the ribosome of a cell, while mRNA travels to the ribosome of a cell during protein synthesis in order to code for the amino acids. Only during protein synthesis will the mRNA appear in a ribosome. mRNA does not make up the structure of the ribosome! Hope this helps! RNA and proteins
