Answer:
Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.
Explanation:
A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:
- Transcription of the mRNA, which will have the sequence of altered bases.
- During translation, the mRNA codons will encode at least one different amino acid.
- The structure of the synthesized protein, which will be altered by changes in its amino acid sequence.
In summary, the <u>deletion of a base in the DNA</u><u> will affect the </u><u>protein</u><u> to be synthesized by </u><u>changing the amino acid sequence</u><u> of its structure</u>.
The other options are not possible, because the deletion of a base in the DNA of a gene
<em> Does not influence the number of chromosomes that the gametes will have.
</em>
<em> It does not produce long chains in the chromosomes.
</em>

The Andean countries have landforms such as mountain peaks, plateaus, and depressions.
Explanation:
The Andean countries are mostly located on the Andean Mountain Range. This is one of the largest mountain ranges in the world, stretching across all of South America, more specifically on its western side, in a north-south direction. This mountain range has created lot of high mountain peaks. There are also numerous plateaus of varying sizes, as well as lot of intermediate depressions.
- These mountains have formed as a result of the subduction zone between the South Americana and Nazca plates.
- There are high peaks on this mountain range across all of its stretching.
- The mountain range is divided into numerous sections, all of which are sharply divided by large depressions.
- There are also lot of plateaus on the Andes, big portion of which have been used for creation of large human settlements.
