Answer:
23 chromosome pairs.
Explanation:
In humans, the DNA strands are packaged in a tightly coiled 1400 nm structure called the chromosomes. Since each cell contains the DNA therefore each cell contains the chromosomes.
The human genome is packaged into 46 linear chromosomes but since the humans are diploid organisms, therefore, the chromosomes form pairs with the homologous chromosomes and form 23 pairs of chromosomes. Every cell of humans possesses 23 pairs of chromosomes.
Thus, 23 pair of chromosomes is correct.
Answer:
2 tentacles but 10 arms
the tentacles are normally the two longer arms.
Shorter mRNA will be found in the ribosomes when comparisons are made
with the mRNA from inside the nucleus.
<h3>Ribosomes</h3>
Ribosomes are organelles which acts as sites for protein synthesis. This is
where the mRNA gets converted into polypeptides which have longer
chains.
Ribosomes have a shorter mRNA in the ribosome which becomes longer in
the nucleus after synthesis of larger polypeptides. this is the reason why
there is a variation in the size of the mRNA found in the ribosome and
nucleus.

By dating the rocks in the ever-changing crust, as well as neighbors such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years.
