Thomson's contribution to the atomic theory was the
discovery that negatively-charged electrons were
embedded within a positively-charged "soup". Later
on Rutherford preformed the gold foil experiment
which altered Thomson's contribution. What were
the conclusions of Rutherford's Gold Foil
Experiment?
O The atom is made up of mostly empty space with a tiny,
dense, positively-charged nucleus.
O The atom is mostly empty space, with negative charge
concentrated at the center.
O The atom is mostly empty space, with positive charges
spread evenly across it.
O The atom is mostly empty space. No other conclusions
could be made.

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4
