<span>b The growth of teeth in chickens supports the hypothesis of a common ancestor between birds and reptiles. This is a generally accepted hypothesis, and i'd go with this answer. Obviously we can't say whether chickens will have teeth with certainty, the chickens with teeth are clearly still chickens, and a baby croc isn't hatching out of a chicken egg any time soon.

Answer:
DNA → TACCATGGAATTACT
RNA → AUGGUACCUUAAUGA
PROTEIN → Methionine-Valine-Proline-Stop codon-Stop codon (AUG GUA CCU UAA UGA)
Explanation:
In nucleic acids (i.e., DNA and RNA), base complementarity refers to the interaction between antiparallel strands. In the double helix DNA molecule, adenine always interacts with thymine (uracil in RNA), while cytosine always interacts with guanine. Moreover, amino acids are encoded by codons, i.e., triplets of nucleotides in the messenger RNA (mRNA). Finally, stop codons are triplets of mRNA nucleotides (e.g., UAG, UAA, UGA) that indicates the end of the protein-coding sequence.
Answer:
Option D. Replace a conventional car with an electric car.
Explanation:
Conventional cars are those which moves with the use of fossil fuels such as petrol and diesel etc while electric cars are those cars which moves with the use of electricity. When fossil fuels burns in the engine of conventional cars, it produces a large amount of smoke which cause pollution in the air while electric cars do not emitt any harmful gases in the environment so electric cars are used instead of conventional cars.
