postcranial changes in hominins that indicate bipedal locomotion include group of answer choices shortening and broadening of th
vredina [299]

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.

In a sample population of people, 36% have the recessive trait of "free" earlobes (q2). What is the frequency of the dominant al
ICE Princess25 [194]

Answer:

Explanation

Given that 36% are recessive in traits

100-36 = 64% for dominant traits considering a whole population to be 100%

P=dominant allele

q= recessive allele

P2= dominant genotype

q2= recessive genotype

according to hardyweinberg principle, p+q=1

64/100= 0.64 frequency for dominant traits or genotype, therefore

p2=0.64

then

P=√0.64

p= 0.8

Therefore, dominant allele frequency (p) for the population is 0.8

finlep [7]

Answer:

I am not sure whether or not this is a statement or a question, but a healthy diet would consist of more diversity. You could live off of that and maintain a healthy body, but it would not be recommended.
