and

D. Cations have more protons than electrons, giving them a positive charge.

B. Anions have more electrons than protons, giving them a negative charge.  

D. Cations have more protons than electrons, giving them a positive charge.

Explanation - Ions are the result of atoms or molecules that lose or gain electrons. If an atom or a molecule is positively charged then it is called as cation and if it has negative charge then it is called as anion.

Cations have positive charge because the atom has lost its electron while anions have negative charge because the atom has gained the electron. The number of protons is more than the electron in cations and less in anions.

How might a single base substitution in the sequence of a gene affect the amino acid sequence of a protein encoded by the gene,
vovangra [49]
The effect differs. It could produce a different amino acid in the sequence because the corresponding codon has changed. It could also prevent the production of the originally intended sequence by changing one of the amino acids of a "start" codon (aka AUG) or extend the protein's sequence by modifying a "stop" codon (UAA, UAG, UGA or UGG), producing a new protein that might be useless or have different effects on the cell.

Why does survival of the fillest not
dlinn [17]

Answer:

Survival of the Fittest means that animals best suited to a certain area will survive, not that the largest will survive. An example of this is the mouse.

Explanation:

When an animal adapts to live longer, they are adapting to their predators and their environment. For smaller animals, like mice, being big might mean that hawks are able to find them easier, leaving only the small mice to reproduce. I hope this helps!
