Answer:
Explanation:
1- Capping occurs at the 5' end of mRNA.
2- The nucleside added is 7-methylguanosine.
3- The nuceloside is connected to the mRNA through a 5′ to 5′ triphosphate linkage.
4- The added nuceloside is modified by methylation at the nitrogen atom.
5- The mRNA is modified by methylation of ribose residues at the 2'-hydroxy position.
your answer would be a characteristic known as albedo temperature
Nerve impulses are caused by Potassium (K+) and Sodium (Na+) ions that are located inside and outside of the cell. The structure of the cell membrane is permeable to Potassium but are highly impermeable to Sodium ions. These impulses are transmitted from one nerve cell to the other in very fast series.
Answer:
It is both a barrier keeping unwanted things out, and a gate for nutrients to be brought in.
I believe the correct answer is the final option - <span>If Earth formations can change over time, it is possible that even life on earth could change over millions of years.
Given that Darwin proposed his ideas about the origins of species and evolution, this is the only possible option to choose. It is impossible that life doesn't change at all, and millions of years are a long time to implement those changes. So it is only natural that organisms can change as much as the Earth can.
