Answer:
That science was able to find more things and discover a lot more things than 300 million years ago.
Explanation:
Science isn't just gathering factual information and data, it's a body of knowledge. It's a way of thinking about problems, and how to solve them. Science shapes everything in our world since everything revolves around natural rules.
It's thanks to computer <em>science </em>that you're able to be on this site right now. It's thanks to <em>science </em>as a whole that we have any of the technology we have today, and the cures for the many once <em>deadly </em>diseases. So, if you want to know how science shapes our world... Just look around you. =)
<em>Energy transformation</em>, also known as <em>energy conversion</em>, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work (Ex: Moving a heavy object from one place to another) On top of that, being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it CANNOT be created or destroyed.
When it comes to transforming electrical energy to mechanical energy, A generator converts mechanical energy into electrical energy, while a motor does the opposite. A motor converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.

Answer:
A frameshift changes every codon past it. A base substitution only changes one codon.
Explanation:
DNA is comprised of nucleotides (A, C, T, G) that make up amino acids. Every three bases is called a codon and represents an amino acid.
In a frameshift mutation, a nucleotide is either added or deleted from the sequence. This offsets the entire sequence after it because the reading frame shifts. Here's an example:
ACTGCTATCGTCATC
If another T is added in between the first and second codons, then every codon after will be changed.
ACT>T<GCTATCGTCATC
A substitution mutation is usually less severe, as it only alters one codon in the sequence. These occur when one nucleotide is replaced by another one. Here's an example:
ACTGCTATCGTCATC
Let's say the first G is replaced by a T.
ACT>T<CTATCGTCATC
As you can see, none of the other codons changed.
Typically, a frameshift mutation is considered worse than a substitution mutation.
