answer:</h2>
a heterogeneous mixture
<h2>
explanation:</h2>
A heterogeneous mixture is commonly any mixture that is not uniform in combination - it's a non-uniform mixture of smaller fundamental particles. Using different means, the particles in the mixture can be separated from one another. In a heterogeneous mixture, the elements do not mix completely, and the individual items that form the mixture can be identified. Heterogeneous mixtures can typically be separated back into their original components by chemical or physical means.
A frame-shift mutation would occur. This is because a
deletion will cause a change in codon sequence from the point of mutation to
the end of the mRNA. If the mutation is
closer to the start of the mRNA, the larger the effect of the mutation on the
translated protein.
Answer:
C.
Explanation:
All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).
Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.
In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.
In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.
In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
