The five steps that are always taken in scientific research are;
- establishing a hypothesis
- doing research and assembling data
- and finally proceeding to a conclusion

- Arya already performs the first two steps; as she first recognize the problem i.e. she observes the dry glass and she also formulate a hypothesis that "the water content in the soil is about two-thirds lower than that of other yards in the area"
- Now she will collect the data and conduct the experiment on the soil and glass and then she will assemble the conclusion based on the results.Now she will collect the data and conduct the experiment on the soil and glass and then she will assemble the conclusion based on the results.

Answer:
1/8 (12.5%)
Explanation:
An autosomal recessive disease is an inherited disease in which an individual need to receive both defective alleles at the same gene <em>locus</em> to be expressed in the phenotype. In this case, both parents are carriers of the recessive mutant allele associated with the sickle cell anaemia trait, thereby both parents are heterozygous, ie., each parent has one copy of the normal allele 'H' and one copy of the defective mutant allele 'h' associated with this condition. In consequence, their first child has a 1/4 (25%) chance of having sickle-cell anaemia. Moreover, the chance of having a girl is 1/2 and the chance of having a boy is 1/2, thereby the final chance of having a girl sickle cell anaemia individual is 1/4 x 1/2 = 1/8 (12.5%).
- Parental cross for sickle cell anaemia trait = Hh x Hh >>
- F1 = 1/4 HH (normal); 1/2 Hh (normal); 1/4 hh (sickle cell anaemia) >>
- Sex proportion of sickle cell anaemia individuals = 1/8 female sickle cell anaemia individuals + 1/8 male sickle cell anaemia individuals (1/8 + 1/8 = 1/4)
