There are three main types of mutation present for DNA. They are substitution, insertion and deletion. Substitution is the exchange of one base for another. Insertion happens where extra base pairs are inserted. Deletions are mutations where a section of DNA is lost. Therefore, the correct answer is substitution.
Metamorphic rocks are formed from existing rocks, when it is exposed to great heat and pressure. This process would destroy any fossils inside the already existing rock.
Two diverse species naturally breed an offspring, and selective preserves raver new traits in a given environment, (they evolve).

Every second this thing moves 75 meters in
the southeast direction. So, 2 secons will be 150 meters, 4 seconds will be 300
meters, etc.
<span>Southeast means something in the middle
between the south direction and the east direction, maybe about -45 degrees. We
can apply Pythagorean theorem:</span>
L1^2+L2^2=hip^2=(75m/s)^2
If East velocity is equal to the south
velocity, both legs will be equal:
2L^2=(75m/s)^2
L^2=(75m/s)^2/2
L = square root [(75m/s)^2/2] = (75m/s)/[square
root (2) ] = 53m/s
So the object is moving about 53m/s to the
east and 53m/s to the south.
