Volume
Explanation:
In chemistry, the CONCENTRATION of a solution is the amount of a substance present within a volume of another substance. In other words, the concentration refers to the amount of a solute dissolved in a particular volume of a solvent to make a solution.
Concentration can be expressed in mass per volume i.e. g/cm³ or mol per volume i.e. mol/L or mol/dm³ etc. The amount of a substance is measured in Mass or mole, while the volume of a substance in Litres (L).
Answer:
A. The two proteins are very likely related evolutionarily.
B. The differences in the sequences in many instances represent a conservative change (such as L for I).
Explanation:
A. Humans and sperm whales are vertebrates and mammals, this implies that they have a common ancestor a long time ago, which makes them evolutionary related.
B. Conservation indicates that a sequence has been maintained by natural selection. This means that protein structure is not exactly the same but is quite similar.
Options C and D, contradict the above explanation, and they make no sense because sperm whales and humans share a common ancestor (mya).
