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.
Answer:
The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. Saturated fats are usually from animal sources, while unsaturated fats are usually from plant sources.

Answer:
The answer is D. Taiga
Explanation:
The taiga biome is also recognized as a coniferous jungle or boreal jungle.
Often times these biomes are extremely wooded with cone-bearing needle-leaved or scale-leaved evergreen trees.
Answer:
It can exchange both matter and energy, exchange energy but not matter, Isolated systems can exchange neither energy nor matter
Answer:
The multicellular sporophyte of bryophytes turns a single fertilization event into thousands new haploid individual(s), whereas fertilization in Chara and Coleochaete leads to four new haploid individual(s).
