Answer:

a. Cells are the basic units of structure and function in living things.

b. New cells are produced from existing cells.

d. All living things are made up of cells.

Explanation:

Cell theory states that cell living organisms are composed of at least one cell, which are the basic unit of life.

Cells are always produced from other living cells, and cannot spontaneously generate.

However, not all cells enclose their DNA within a nucleus, prokaryotic organisms (bacteria) do not possess a nucleus but still have DNA

The nurse places the stethoscope on the 3rd intercostal space at the left sternal border. Which area is the nurse auscultating f
miv72 [106K]

The nurses auscultated for heart sounds in the area of Erb point.

The fifth point of auscultation for the heart test, known as "Erb's point," which is occasionally given to the eminent German neurologist Wilhelm Heinrich Erb (1840–1921) without any supporting documentation, is positioned in the third intercostal gap near the sternum. At the third intercostal gap and the left lower sternal border is the auscultation location for heart sounds and heart murmurs known as Erb's point.

The spinal accessory nerve in the posterior nerve triangle is located at Erb's point (also known as the great auricular nerve) at the location where it enters the trapezius muscle. At the end of expiration, the third intercostal gap on the left (Erb's point) is often the ideal place to detect the murmur of aortic regurgitation because it is quiet, high-pitched, early diastolic and decrescendo.
