Ancillary care refers to the wide range of healthcare services provided to support the work of a primary physician. These services can be classified into three categories: diagnostic, therapeutic, and custodial. Diagnostic services include laboratory tests, radiology, genetic testing, diagnostic imaging, and more.
Mars has an axial tilt of 25.19Â°, quite close to the value of 23.44Â° for Earth, and thus Mars has seasons of spring, summer, autumn, winter as Earth does. As on Earth, the southern and northern hemispheres have summer and winter at opposing times.
The tilt of the Earth's spin axis with respect to the plane of its orbit about the sun (the ecliptic plane) is important for a habitable Earth. The Earth's spin axis is tilted 23.5Â° with respect to the ecliptic, giving moderate seasons and preventing temperature extremes anywhere on the planet. This illustration, patterned after Ward and Brownlee, summarizes the effects of different tilt angles with respect to the ecliptic plane.
