Answer:
H2O
Explanation:
The chemical formula of water is H2O . which means two hydrogen atoms and one oxygen atom in each molecule of water.
Equation:
The equation for H20 is H2O= H2+02.
Answer:
Father’s phenotype non roller Father’s genotype rr
Mother’s phenotype roller Mother’s genotype Rr
Probability of this couple having a child who is a tongue roller : 1/2
Explanation:
Given that allele for rolling (R) is dominant over allele for non rolling (r).
Since father is a non roller his genotype would be rr
Mother is a heterozygous tongue roller so her genotype would be Rr
Their progeny:
Rr X rr :
R r
r Rr rr
r Rr rr
Half of the offspring have Rr genotype which will make them tongue roller so probability of this couple having a child who is a tongue roller is 1/2.
