<h2>Depending on the organism, these needs may include: air, water, nutrients, food, light, shelter, space, certain temperatures, etc. Plants need soil, nutrients, sunlight, water, space, air and appropriate temperatures to survive. Animals need food, water, shelter, oxygen, space and appropriate.  You can write:  Organisms need air, water and food from their environment.  I hope this helps you!  </h2>

Answer:
 D.) repressor DNA-binding site mutation
Explanation:
lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".
The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence. 
This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.

The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.
