The dalton or unified atomic mass unit is a unit of mass widely used in physics and chemistry. It is defined as 1⁄12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. The atomic mass constant, denoted mᵤ is defined identically, giving mᵤ = m/12 = 1 Da.

kkurt [141]
<span>Pillow lavas have pillow-like structures and are formations that push lava on the surface of the earth underwater. Magma comes out of ocean ridges as pillow lava and forms a new oceanic crust, supporting sea floor spreading. The older crust gets pushed away from the ridge and pushes on to the continents, making them drift.</span>

What is the development of lymphocytes compared to other formed elements?
Katyanochek1 [597]
Lymphocytes and the other formed elements are developed from pluripotent stem cells. The pluripotent stem cells generate myeloid stem cells and lymphoid stem cells. Myeloid cells start and complete their development in red bone marrow and give rise to red blood cells, platelets, eosinophils, basophils, neutrophils, and monocytes. Lymphoid stem cells begin development in the red bone marrow, but some are completed in the lymphatic tissues, where they give rise to lymphocytes. The B cell lymphocytes begin and finish in the red bone marrow and the T cell lymphocytes begin in the red bone marrow, but they mature in the thymus.
