Various advancements that have occurred in the field of biology have helped us gain a better understanding to fight against various infectious diseases. Biology has helped us study the life cycle of various parasites, pathogens, and vectors along with the modes of transmission of various diseases and the measures for controlling them. Vaccination programmes against several infectious diseases such as small pox, chicken pox, tuberculosis, etc. have helped eradicate these diseases. Biotechnology has helped in the preparation of newer and safer drugs and vaccines. Antibiotics have also played an important role in treating infectious diseases.
A current-carrying coil is placed in an external uniform magnetic field. The coil is free to turn in the magnetic field. What is the net force acting on the coil? Obtain the orientation of the coil in stable equilibrium. Show that in this orientation the flux of the total field (field produced by the loop + external field) through the coil is maximum.
Any adverse variation from an organism's normal structural or functional condition is usually associated with specific signs and symptoms and distinct from physical injury.
A few diseases appear out of nowhere and persist only a few days. Acute diseases, such as the common cold, are examples of them. Acute diseases frequently become chronic if they are not treated.
Acute diseases include strep throat, fractured bones, appendicitis, influenza, pneumonia, and others.
Acute diseases develop quickly and are accompanied by unique symptoms that necessitate immediate or short-term treatment and improve once treated. Acute illnesses, such as the common cold, can sometimes go away on their own.
Chronic diseases are illnesses that develop over time and endure for a long time or even a lifetime. Chronic disease is defined as a disease that lasts more than three years. The symptoms are relatively modest at first.
