Answer:
When E. coli is grown on glucose, and there is no lactose available
the lac repressor binds to the operator of the lac operon
Explanation:
Genetic diversity decreased as the human population migrated from Africa to other continents because each migration had a chance to obliterate one or more genetic variants.
<h3>
What is genetic diversity?</h3>
The term "genetic diversity" refers to the entire gene pool that a population or species possesses in a specific habitat.
During migration, genetic diversity is essential for adjusting to new environmental situations.
The genetic diversity decreased when the human population migrated from Africa to other continents since each migration had a chance of bringing with it one or more genetic variants.

The given blanks can be filled with NADPH and ATP.
The dark reactions or light-independent reactions of photosynthesis refers to the chemical reactions, which transforms carbon dioxide and other constituents into glucose. These reactions take place in the stroma, that is, the fluid occupied region of a chloroplast external to the thylakoid membranes. These reactions use the products of light-dependent reactions, that is, NADPH and ATP to do further processes.
Fossil evidence suggests that the tiktaalik had lungs, which meant that it could breathe in air, instead of just water.
This trait allowed the tiktaalik to survive despite the low oxygen content of the shallow water because the tiktaalik would simply get its oxygen from the air. This selective advantage was passed on to the tiktaalik's offspring and over time, more amphibious creatures evolved with the ability to survive both on land and in water.
The answer would be C as it can be directly tested experimentally and observed that bacteria adapted to become drug resistant and the natural selection of drug resistant bacteria to survive and continue proliferating, thus being direct evidence of evolution
