Answer:
The correct answer is ''carbon dioxide, water vapor and nitrogen.''
Explanation:
About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.

Answer:
D.Singed bristles/vestigial wings and normal bristles/normal wings
Explanation:
Parent 1: singed bristles and normal wings ( ssLL )
Parent 2: normal bristles and vestigial wings (SSll)
ssLL X SSll =
F1: SsLl ( normal wings and normal bristles )
SsLl X ssll =
F2:
Sl/sl = normal bristles and vestigial wings = Parental
sL/sl = singed bristles and normal wings = Parental
SL/sl = normal bristles and normal wings = Recombinant
sl/sl = singed bristles and vestigial wings = Recombinant
since, singed bristles/ vesitigal wings and normal bristles/normal wings are different from parental combinations, they are the recombinant offspring.
