Nails form from molten iron is considered a Physical change. Why? The molten iron is just heated in order to form a different shape which is the nail but its chemical composition is still the same. The chemical composition of the nail is still the same with iron.
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).

Glucose is the simple sugar that provides energy to organisms.
DNA polymerase is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules. Polymers are Nucleic Acid, which are large molecules made up of smaller, repeating units that are chemically connected to one another.
