DNA makes us all unique by controlling the production of <u>gene</u> that make us look different and have the structures to better survive within our <u>environment</u>.
Explanation:
DNA is the molecule that contains the genetic information, dependent on the sequence of nucleotides that form its structure.
Chromosomes are formed by a DNA molecule, whose fragments form genes, structures that define every characteristic and function of a living being.
The <u>characteristics expressed by the genes differentiate individuals of the same species and other species</u>, allowing their functions, including <u>survival in their environment</u>.
Only a few organisms react to their environment to survive. The statement is TRUE because <span>some organisms are able to adjust and even thrive and many of them cannot do the same and hence their populations' decreases.</span>
