A student would like to determine how heating a liquid changes its volume. The student hypothesizes that the liquid will increas

e in volume. The following list shows the steps taken by the student in order to test the hypothesis.
Select the liquid to test.
Place the liquid in a sealed container.
Use a Bunsen burner to heat the liquid by 10°C.
Measure the volume of the liquid.
Record the results.
What is wrong with how the student conducted the investigation?
A.
The length of time it took for the liquid to be heated should be measured.
B.
The hypothesis was not valid because it is impossible for liquids to change in volume.
C.
The volume of the liquid should be measured before it is heated.
D.
The student should have increased the temperature of the liquid by more than 10ºC.

This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.

My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.

This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.

Dmitriy789 [7]

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.
