Option A: Postcranial changes in hominins that indicate bipedal locomotion include shortening and broadening of the ilium of the pelvic girdle.
Around 3 million years ago, bipedal locomotion in early hominins turned to be more effective. This adaption made the hominins more stable to hold their weight and walk upright. It also helped them to see longer distances in the green forests areas. They could take the advantage of hunting their food or protecting them from harmful predators. Adapting bipedal location expended lesser energy, thus allowing hominins to walk longer distances.
Over many generations now, bipedal location turned out to develop stronger and longer legs and feet so as to allow running and holding more weights. Additionally, the arms turned to be more adapted to hold the heavier things efficiently and to carry their newborns effectively.
Owing all these changes, adaption made to this kind of locomotion include shortening and broadening of the ilium of the pelvic girdle and developed a bowl-shape structure.
Thus, option A is the correct answer.

Hello there.
Mate 2 dogs that have the desired trait, Any farther questions just ask.
Hope this helps.
As DNA replication begins the DNA molecule is broken apart into two complementary strands. DNA replication is the process by which DNA makes a copy of itself during cell division. The process occurs in all living and is the basis for biological inheritance. The process starts with the separation of DNA strands in the double helix. Then replication for is formed followed by the binding of bases to each strand. Then the last step is termination of the Replication process
Answer;
-Gametic Isolation
Explanation;
-Gametic isolation is a type of prezygotic barrier where the gametes (egg and sperm) come into contact, but no fertilization takes place.
-In Gametic isolation is when sperm of one species may not be able to fertilize the eggs of another species. For instance, sperm may not be able to survive in the reproductive tract of females of the other species, or biochemical mechanisms may prevent the sperm from penetrating the membrane surrounding the other species' eggs.
