Orbital period is the <span> time taken for a given object to make one complete </span>orbit around another object. Mercury orbits the Sun in 88 days. Therefore, Mercury's orbital period is calculated by (88/365.25) or .241 Earth years. Hope this answers the question.

Orbital period of mercury can be calculated using the third law of Kepler which states that period squared equals to distance cubed, that is, (T1/T2)^2 = (a1/a2)^3 Where T1 is the orbital period of mercury, T2 is the earth orbital period and is equal to 1 year, that is, 365.25 days. a1 is the mercury axis and is equal to 0.39AU while a2 is the earth axis and is equal to 1AU. T^2 = (0.39)^3 = 0.059319 Therefore, T1 = 88 days.

Galina-37 [17]

The image provided is not clear, however, the correct and clear image is attached with the answer:

Answer:

The correct answer is - 100 %

Explanation:

As we know DMD or Duchenne Muscular Dystrophy is a sex-linked recessive disorder and according to the given pedigree, it is clear that Individual I-1 is a normal male and 1-2 is a female who has two defective genes of the disorder as if she had only one defective gene she would have a carrier for the disorder.

All gametes produced by both male and female would be -

Male - X and Y

Female - Xd and Xd

Therefore all the male offsprings or son will get one defective gene Xh from the mother for sure and a Y chromosome from the father. All daughters will also carry one gene Xh that is defective from the mother and normal X from the father but would be carriers for the disorder.
