Mutations are random and rare changes in the DNA sequence that can both add or delete genes. (therefore, all of the answers listed above apply)

In genetics, the term mutation represents any change in the DNA sequence of an organism. Mutations can be limited to a change in just a single nucleotide ( Single Nucleotide Polymorphisms) or it can include deletions, insertions or translocation of a longer DNA sequence, sometimes even whole genes. Mutations are rare and random events, but there are some places in the genome that are more prone to genetic mutations, called ''hot spots''.

47. Beaches and barrier islands along Florida's coast often change shape quite dramatically when a hurricane or other
Advocard [28]

Answer:

The answer is letter D, The storms cause wind and waves that move the sand from one place to another.

Explanation:

Along the coastline of Florida are their <em>beaches and barrier islands. </em><u>These islands are very important for the survival of plants and animals. </u>However, whenever a hurricane or a storm hits the area, it causes a dramatic change in the shape of the place. This is, primarily, because the storm causes the forces of wind and waves to move the sand from one place to another.

The movement of these can be towards or away from the mainland. <em>The fast movement</em> <u>causes the sand in the area to be deposited away from the shore,</u> thus creating sandbars. <em>The slow movement</em> <u>causes the sand from the sandbars to return back to the shore.</u>
