The chemical secreted by the tapeworm is noted to slow down the intestinal pulsation, if added to drug for humans it might increase the drugs effectiveness by ensuring the drug stays in the lower alimentary canal for long, ensuring maximum absorption the drug components into the body's blood stream as it will not be ejected from the body at the normal rate

- C. point mutation
- F. translocation
- A. mutation
- H. duplication
- G. inversion
- D. frameshift mutation
- E. insertion
Explanation:
Mutation:
A mutation is a change or alteration of the sequence of nucleotides in the DNA.
Mutations are of various types. Two of the major types are:
- Point mutations
- Chromosomal aberrations.
- Point mutations are changes in one or two or a few nucleotides of DNA. Point mutations are further of various types:
- Substitutions are exchanges of one nucleotide with another. Substitutions are also of three types: nonsense (codon changes to stop codon), missense (codon codes for a different amino acid) and silent mutations (codon codes for the same amino acid).
- Insertions/deletions are the addition or removal of one or a few nucleotides. Frameshift mutations alter the DNA reading frame, changing all the consequent amino acids.
- Chromosomal aberrations constitute translocations (part of one chromosome attaches to another), inversions (the orientation of the chromosome is altered), insertions (duplication or insertion of multiple copies of a chromosomal segment) and deletions (deletion of a chromosomal segment).
<u>Answer and explanation</u>;
- <em><u>Variations in the structure account for functional differences among membranes by their protein. Different types of cells contain different sets of membrane proteins which carry out different functions. </u></em>
- For example; In the cell membrane, there are embedded proteins that function in transporting nutrients into the cell, and waste products out of the cell.
- In the membranes of the mitochondria, proteins are needed to serve as electron carriers. organization of proteins determines the function.
