How does the sea ice in 2019 compare to the sea ice in 2012 during April?

Katarina [22]

The total amount of sea ice showed a decline from 2012 to 2019. The correct option would be D.

<h3>Graphical illustration</h3>

Looking at the graph, from February to June 2012, there is a decline in the amount of sea ice.

A similar decline in the amount of sea ice can be observed in the year 2019.

However, the sea ice levels for the various months in 2012 remain generally above the sea ice levels in the various months in 2019.

Thus, overall, one can say there is a general decline in the ice level from 2012 to 2019.

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

<em>The DNA sequences may vary but the amino acid sequences are identical. </em>
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the <u>genetic information contained in the DNA varies from one species to another</u>, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.
