<u>Answer:</u>
Point mutations occur when only one nucleotide is altered affecting only one location or point of the DNA strand.
While Frameshift mutations are caused by the deletion or insertion of a number of nucleotides.
These altered nucleotides affect the triple nature of gene expression disturbing the whole reading frame. All the codons after mutation are different translating a completely different protein. That's why frameshift mutations cause more problems than point mutations.
Villi increases the surface area to help with absorption and digestion. Micro-villi form a brush border that vastly increases the surface area of the plasma membrane so larger amounts of nutrients can be absorbed.
The answer to this question is B.
