I think that the answer is C- "I RNA contains uracil and ribose." because it is the one that mostly makes sense and is the one that most shows the difference between RNA from DNA.
According to google: "Ribonucleic acid (RNA) is a polymeric molecule implicated in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with proteins and carbohydrates, constitute the three major macromolecules essential for all known forms of life."
I hope this helped!

Answer: A. ancestral trait
Explanation:
Bipedalism can be define as a form of terrestrial locomotion, in which the organism moves with the help of two rear limbs or legs. Typical bipedal movements includes the hoping, running and walking. The evolution of the human bipedalism occurred in primates in about 4 million years ago with Sahelanthropus (oldest human ancestors or African Apes). The human ancestor Sahelanthropus led to the morphological alterations in the human skeleton including changes in the bones such as size of the bones of the foot, knee size, shape and orientation of the vertebral column, and leg length. All these changes contributed to the bipedalism.
