Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.

Answer:
The surface projections of the heart represent points on the thoracic wall that map out the outline and valves of the heart. These include four borders (superior, right, inferior, left) and four valves (left atrioventricular, right atrioventricular, aortic, pulmonary). The main reference points used for the surface projections of the heart are the borders of the sternum and costal cartilages, the clavicle and intercostal spaces. The latter favour sound transmission, facilitating clinical maneuvers such as percussion, auscultation and palpation to pinpoint the cardiac location.
Therefore, surface projections of the heart are essential for basic clinical practice. During auscultation, clinicians use a stethoscope to listen to sounds above specific localizations of the heart, such as heart valves. Heart sounds and additional murmurs can reveal cardiovascular system diseases like valvulopathies or vascular malformations, such as a patent ductus arteriosus
