Answer:
When populations are separated by a barrier forming a new species
Answer:
If two breaks occur in one chromosome, sometimes the region between the breaks rotates 180 degrees before rejoining with the two end fragments. Such an event creates a chromosomal mutation called an inversion.
Answer:
The bicondylar angle positions the center of mass above the base of support during the single-support phase of bipedal locomotion.
A. True
Explanation:
The bicondylar angle is the functional angle between the diaphysis of the femur, perpendicular to the intercondylar plane. Very unique to humans, this angle places the knee and the foot under the body's center of gravity during a single support phase of locomotion or gait. With hip joints set lateral to the body's midline, the bicondylar angle aligns the lower limb with the center of gravity, thereby facilitating human movement.

Answer:
Option A, Donates H+ ions when conditions become too basic and accepts H+ ions when conditions become too acidic
Explanation:
Buffer solutions have the ability to maintain stability of pH of the solution. They resist any changes in the pH of the solution on addition of an acid or a base component or solution.
Every buffer solution has a buffer capacity and range. Buffer capacity depicts the amount of acid or base solution is required to change the pH of the solution by 1
.
Hence, option E is correct
