Based on many assumptions, the conditions on nearly earth, some three to four billion years ago, are thought to be much different before from what they are today. The theory called big bang is defined proposing that the earth was once part of a larger particles that coalesced after the universe initial explotion.
Answer:
![0.547](https://tex.z-dn.net/?f=0.547)
Explanation:
Given -
Total Population - ![500](https://tex.z-dn.net/?f=500)
Individuals with homozygous HbA/hbA genotype - ![150](https://tex.z-dn.net/?f=150)
Individuals with homozygous hbs/hbs genotype -![150](https://tex.z-dn.net/?f=150)
Individuals with heterozygous hba/hbs genotype - ![200](https://tex.z-dn.net/?f=200)
Let us assume the given population is in Hardy Weinberg' equilibrium
The frequency of individuals in the given population with homozygous HbA/hba genotype is equal to number of individuals with homozygous HbA/hba genotype divided by total population.
![\frac{150}{500} \\= 0.3](https://tex.z-dn.net/?f=%5Cfrac%7B150%7D%7B500%7D%20%5C%5C%3D%200.3)
The frequency of hba allele is equal to
![\sqrt{0.3} \\= 0.5477](https://tex.z-dn.net/?f=%5Csqrt%7B0.3%7D%20%5C%5C%3D%200.5477)
I do believe the answer is B because since it is going through each phase, the DNA strand will continue to adjust itself as the cell moves making the strands split allowing themselves to create copies. Since DNA has to be connected with another strand that will fit, it will be able to multiply itself based on the pieces that are missing
