The correct answer will be option A-the accepted model of the atom was changed.
Explanation:
J.JThomson discovered the electrons by cathode ray tube experiment in 1897 and realized that the accepted model of atom as proposed by the Dalton has problems as he stated that "atom is indivisible".
The discovery of sub-atomic particles-electrons in his experiments showed that the atom can be divided into sub-atomic particles and he proposed the pudding model of the atom which changed the accepted model of atom at that time.
Thus, option A-the accepted model of the atom was changed is the correct answer.
Answer: 25% are homozygous with the dominant gene (VV), 25% are homozygous with the recessive gene (vv), and 50% are heterozygous (Vv). Only the flies with vv will display the trait.
