Earth's tilt on its axis affects the way heat is distributed on Earth's surface.
The Earth orbits the sun every 365 ¼ days. The Earth is tilted 23.5 degrees on its axis, which affects the distribution of the sun’s energy across the surface of the planet. More tilt means more severe seasons, that is warmer summers and colder winters where as less tilt means less severe seasons, that is cooler summers and milder winters.

The answer is B.
neutral: OH- = H+
acid: H+ > OH-
base OH- > H+
Yes, this will be a silent mutation.
Explanation:
The mutation which occurred in the human insulin gene where the first codon was changed to CCG will be a silent codon because this will not change the sequence of the amino acid and the amino acids formed will remain the same.
A silent mutation occurs due to base substitutions resulting in a change in the nucleotide that does not impact the amino acid or protein formed once the mRNA is translated. The protein will retains its functional aspects.
Answer:
First off, the info tells me that bandicoots, sea lions, and zebras could have all shared a common ancestor at one point in time and then developed differences to be better suited to their respective environments. Further, the similarities in their body structures cannot be attributed to convergent evolution (evolution that produces analogous structures) because the three organisms grow in very different environments; thus it had to have come from homology (common ancestry). Having said that, this tells us that the ancestors most likely had the trait of whatever is shared amongst the body structures of bandicoots, sea lions, and zebras, as this was the trait they passed on. Hope this is helpful :)
