Answer:

here is answer mate

Explanation:

Disease, any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury. A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state. Thus, the normal condition of an organism must be understood in order to recognize the hallmarks of disease. Nevertheless, a sharp demarcation between disease and health is not always apparent.

Injury, infection or an unhealthy lifestyle can all make you ill. So can your genes, the instructions that tell your body how to make all the different proteins it needs to survive and grow. A change in a gene may cause a change in a protein, affecting the way it works in your body. Some genes are involved in common illnesses, while others cause rare genetic conditions.

The search for the causes (etiologies) of human diseases goes back to antiquity. Hippocrates, a Greek physician of the 4th and 5th centuries bce, is credited with being the first to adopt the concept that disease is not a visitation of the gods but rather is caused by earthly influences. Scientists have since continually searched for the causes of disease and, indeed, have discovered the causes of many.
