For example: GGATACCTAGGTAAT
Insertion: GGAT<u>G</u>ACCTAGGTAAT
a nucleotide that was not present before is inserted into the original sequence
Substitution: <u>C</u>GATACCTAGGTAAT
the first nucleotide was substituted in for another (C for G)
Frameshift (basically a insertion or deletion, we'll try deletion here): GATACCTAGGTAAT
the first nucleotide was deleted, causing the reading frame to be shifted (instead of GGA as the first codon, we have GAT)
Trenches are geological feature is most common at oceanic-continental convergent boundaries.
Explanation:
Usually, the oceanic plate, because it is denser, becomes subducted underneath the continental plate. The enormous stress of the two colliding plates causes the plates to warp abit downwards along the boundary causing a trench to form that stretches the boundary.
As the oceanic plate gets subducted and ‘dives’ into the mantle, it begins to melt into magma. Usually, due to the enormous stress along the boundary, fissures develop on teh continental plate along teh boundary. The magma rises through these fissures and erupts at the surface. Several mountains form long the boundary forming another signature geological feature of convergent boundary which is volcanic arc mountains.

<h2>Answer:</h2>
The two reasons are given below:
- Natural selection.
- Lack of food
<h3>Explanation:</h3>
Natural selection is the phenomenon of the evolution in which the organisms able to fit in the changing environment survive while other organism died. Hence the survival if the fittest and then these organisms. Further reproduce to give birth organisms more fit to the changing environment.
The long neck giraffe survive but short neck died. So the population of long neck increased while short neck go extinct.
Other reason is the change of food resource. The food resource change from grass to long trees.
The continental drift affects living organisms in that it causes changes in climates which puts selective pressure on organisms, causes changes in habitats, including when large amounts of shallow marine habitat were lost in the formation of Pangea. Additionally continental drift may cause an increase or decrease in competition among different species and also it happens so slowly that it does not affect living organisms
The way that the number of injuries per cat relate to the number of stories a cat falls is that:
- As we examine the data about cats dropping from a given number of stories, a tendency becomes obvious. The cat sustains more wounds from story one to story eight than in the previous stories combined. Despite the fact that there are fewer injuries in the last category.
<h3>Why do cats survive after jumping off of a tall building?</h3>
High-rise syndrome describes the wounds that cats can get when they fall from a steep height, like an inside second-floor landing or balcony, out a window, down a fire escape, or when they fail to jump from a landing to a higher architectural element, like a ledge or window.
Cats may live comfortably in apartments and high-rise buildings, but we must make sure they have enough stimulation and playtime.
Therefore, According to Jim Usherwood of the Royal Veterinary College's structure and motion lab, stated that cats have long, flexible legs. "They have respectable muscle mass. Since they can jump rather well, the same muscles focus their efforts on slowing down rather than shattering bones."
