I think the correct answer from the choices listed above is the last option. It would be 50 <span> full-length strands of hair are collected from the scalp to use as a sample. The more sample the better because you can easily repeat an experiment if there are errors found. Hope this answers the question.</span>

Answer:
The mutations occur at a rate of 0.56 base changes every 1 billion years. If this rate stays consistent, the mutation rate can be used to determine when different lineages of a particular species split
Proteins attract water and hold it within blood vessels, preventing it from freely flowing into the spaces between the cells. This is an example of how protein is used for maintaining fluid and electrolyte balance.
<h3>What is Protein?</h3>
- Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues.
- Among the many tasks that proteins carry out in living things include catalyzing metabolic processes, replicating DNA, reacting to stimuli, giving cells and organisms structure, and moving molecules from one place to another.
- The primary way that proteins differ from one another is in the order of their amino acids, which is determined by the nucleotide sequence of their genes and typically causes a protein to fold into a certain 3D structure that controls its activity.
<h3>What Constitutes Proteins? </h3>
- Amino acids, which are tiny chemical compounds with an alpha (central) carbon atom coupled to an amino group, a carboxyl group, a hydrogen atom, and a variable component known as a side chain, are the building blocks of proteins.
