'RNA is transcribed and translated in the cytoplasm', 'transcription produces an mRNA ready for translation' and 'RNA is proofread for errors' occur in prokaryotes, whereas '5′ cap, 3' poly-(A) tail and RNA splicing' occur in eukaryotes.
The prokaryotic cells (e.g., bacterial cells) do not contain cell nuclei, thereby the messenger RNA (mRNA) must be transcribed and translated in the cytoplasm.
During prokaryotic transcription, the RNA transcript is proofread for errors. In bacteria, DNA polymerases proofread the transcript by using their 3’ → 5’ exonuclease activity.
In eukaryotic cells, RNA processing consists of several mechanisms:
- A 7-methylguanosine cap (5′ cap) is added to the 5′ end of the precursor messenger RNA (pre-mRNA).
- A 3' poly-Adenine (A) tail is added to the 3' end of the pre-mRNA.
- Both the 5′ cap and 3' poly-(A) tail protect the RNA transcript from its degradation by exonucleases.
- Eukaryotic RNA splicing consists of the removal of non-coding regions called 'introns' and subsequent splicing of the protein-coding regions called 'exons'.

The vas deferens are a fibromuscular tube which connect to the epididymis, and is an excretory duct of the testis.
Hope I could help! :)
Answer:
It's always associated with motion
It can be transferred from one object or body to another
Explanation:
Kinetic energy is the energy due to motion of a body.
- Moving objects possess kinetic energy which is resident in that body.
- As with other forms of energy, it can be transferred from one body to another.
- Kinetic energy can express itself as thermal energy, electrical energy, mechanical energy etc..
- As a body moves, the kinetic energy is increases.
not really familiar with all this but I think 1. Relative dating is where they estimate or relatively guess around how old it is so you could just put something like "an estimate of the age" or something
