Answer:
<h2>
Protein exists in different forms- primary, secondary, tertiary and quaternary structure.</h2>
Explanation:
Primary structure of protein consists of amino acids joined by a peptide bonds. Peptide bond exists as covalent bond. Secondary structure of protein is stabilized by hydrogen bonds. Tertiary structure is stabilized by hydrophobic interaction, electrostatic interaction and disulphide bonds. Similarly, quaternary structure is stabilized by non-covalent interactions and disulphide bonds. So, each structure of protein is stabilized by different types of bonds.
In several ways, the scientific method is similar to medical diagnosis:
In medical diagnosis, the state of the patient's health is being observed. This involves examining the patient and performing measurements like taking temperature and blood pressure, or analysing blood and urine sample.A possible explanation or hypothesis, such as the presence of a specific disease, is then proposed.
The hypothesis is tested. This involves treating the patient for the condition, for example, by administering a medicine.The patient is observed again to determine whether the proposed explanation and the treatment based on it were correct. If the symptoms disappear, the diagnosis (hypothesis) is confirmed; is not another explanation may be necessary.
