Answer:
22
Explanation:
the egg of a rabbit contains 22 chromosomes, a somatic cell of a rabbit would contain twice as many chromosomes, for a total of 44
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.

Most mountains and mountain ranges are parts of mountain belts that have
formed where two lithospheric plates have converged and where, in most
cases, they continue to converge.

Answer:
Mother
Explanation:
The mutation needs two X chromosomes. Only the mother has two X chromosomes (XX). The father is male, so he only has one X chromosome (XY)
