Do the islands appear to be the same age, or are they older at one end of the chain or another? Explain what
AlekseyPX

Answer:

Some islands have older islands at one end of the chain and younger islands at the other end. Example is the Hawaiian Islands.

Explanation:

Volcanic mountains or islands are formed when the tectonic plates in the earth’s crust converges. The string of Hawaiian volcanic islands were formed as a result of the movement of the Pacific plate over a fixed hotspot, where the magma rises upward and erupts on the seafloor. The northwestern islands are older than the islands to the southeast side of the Hawaiian islands.

The age of a volcanic rock is calculated by measuring the amount of argon and the amount of radioactive potassium present in the rock. These measurements are the supporting evidence which showed that the southeastern end of the chain is younger than the northwestern part of the chain. The volcanic islands gradually subside and erode as they age, so the older islands have much lower elevations than the newer islands. This is another evidence which supports the conclusion.

Reorder by size<br> Cell, nucious DNA, chromosoma,gen, nucleoti
sp2606 [1]

Answer:

Explanation:

The arrangement below is from the smallest to the biggest

nucleotide → nucleus DNA → gene → chromosome → cell

The nucleotide is the smallest because it is what makes up the DNA, it is made up of a nitrogenous base, ribose sugar and a phosphate group.

Nucleus DNA follows because it is bigger than a nucleotide (as said earlier) but is singly found in the chromosome which is present in the nucleus.

The gene, which can be assumed to be the entire genome of the organism, involves both the chromosomal gene and the extrachromosomal gene (like the mitochondrial DNA).

Chromosome is made up of a DNA molecule and protein which makes it bigger than the Nucleus DNA and the gene because it contains several genes.

The Cell contains all the molecules/organelles mentioned above and as such is the largest among them all.

Note that the spellings the question are wrong and have been corrected in the answers provided
