Answer:
The correct answer is a Protein
Explanation:
Proteins are macromolecules consisting of amino acids which are joined by peptide bonds.
Protein molecule has two ends, amino(-NH2) group is present at one end that is known as amino terminal end or N terminal end whereas carboxyl group is present at the another end that is called carboxy terminal end or C terminal end.
The statements which are true about half-life are given below:
- A radioactive element's half-life stays the same when its temperature changes.
- A radioactive element's half-life stays the same when the pressure upon it changes.
Thus, the correct options are B and F.
<h3>What is Half-life?</h3>
The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.
The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.
Therefore, it is well described above.
