Answer:
The correct answer is
1. 5' end.
2. guanosine
3. 5′ to 5′ triphosphate linkage.
4. On the 7th position.
5. 2′ hydroxy-groups of the first 2 ribose sugars.
Explanation:
The eukaryotic mRNA is processed or modified with a guanosine cap at 5' end and poly-A tail at 3'end before translation.
The process of adding a cap at 5' end of a growing mRNA is known as capping. The process of capping adds guanosine nucleotide at the 5'-end of mRNAs by 5′ to 5′ triphosphate linkage. This guanosine is modified by methylating at the 7th position of the atom. The mRNA is further modified by methylation of first two ribose sugars at their 2′ hydroxy-groups. This capping is advantageous to the sequence as it protects the end from phosphatases and nucleases.

The electrolytes present in our body should be in the right concentration. This is said to be electrolyte balance.
Why does an electrolyte imbalance occur?
Electrolyte imbalance is caused when the body fluids are present in large amount. When we sweat or vomit more, it can be due to the lower level of some electrolytes. So, it is necessary that the electrolytes should be in proper proportion.
Electrolytes plays a very important role in our body. It helps in regulation of fluids present in blood and blood plasma, normalizes the pH of blood, allows the contraction of muscles and so on. For all these necessary roles to occur, our electrolytes should be in proper concentration. This is called electrolyte balance.
