the answer is D, a trait passed on from parent to offspring
I believe the purpose of the horns in the monsters is to make them look scary for work and thus appear charming to the monster sexes. Assuming that the monsters mate sexually, the selection of the horn numbers will depend on the whether more numbers of it make one look beautiful or whether it incurs any work related advantage. A small monster colony has a large amount of monsters that have an abnormal amount of horns. This indicates that the abnormal number of horns are preferred over fewer horns as they carry a certain advantage of having a scarier look.
Answer: Though the answer were not given, the complementary RNA strand is 5'UCCGAGGUC3'
Explanation: RNA is a single stranded nucleic acid produced from DNA. Four bases are usually found in DNA and they include adenine, Uracil, cytosine and guanine whereas adenine, thymine, cytosine and guanine are found in DNA. In RNA base pairing, wherever adenine is found in the DNA template strand, uracil occurs in the RNA strand, wherever thymine is found in the DNA template strand, adenine occurs in the RNA strand and anywhere cytosine occurs in the DNA template strand, guanine occurs in the RNA strand. This means that adenine pairs with uracil, cytosine pairs with guanine and thymine pairs with adenine.
