The protein separates from the ribosome in which step of transcription

First of all, protein synthesis is translation not transcription. So I will take it that you just typed this wrong. 

So, translation of mRNA into the protein ends at a step called termination. Termination happens when a stop codon in the mRNA (UAA, UAG or UGA) enters the A site. These stop codons are recognized by proteins called release factors which fit into the P site of the ribosome (note these are not tRNAs). These release factors mess with the enzyme that normally forms peptide bonds - and this then separates the chain from the tRNA and the newly made protein gets released. the small and large ribosomes then separate from eh mRNA and can go do another round of translation with another mRNA (good recycling!!). 

No because the eaeht is on a 23.5 degree axis tilt and so when it is winter the northern hemisphere is pointing away from the sun and the soutubern hemisphere is pointing toward the sun

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
