Answer:

The correct answer is D. Scientists used evidence, analysis, and experiments to disprove  alchemy.

Explanation:

Alchemy was based on changing a non-precious material into a precious material like lead into gold. It was considered as magic and science before the 19th century because in the 19th-century scientist get to know about the nature of metals and the periodic table that disproved alchemy.

Alchemist said that everything is made up of soil, water, fire, and earth but after the advancement of chemistry and physics it became clear that everything is made up of atoms, and lead is also made up of atom which can not be converted into gold.

So scientist used evidence, analysis, and experiments to disprove alchemy. Therefore the correct answer is D.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
blondinia [14]

Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
