26) The incorrect sentence is:<br />d) Mean arterial pressure (MAP) is responsible to keep the blood flow to the heart.<br /><br />Mean arterial pressure (MAP) is the average pressure in the arteries during a single cardiac cycle. It is not responsible for keeping the blood flow to the heart, but rather it represents the driving pressure that propels blood through the circulatory system.<br /><br />27) The correct order of the electromagnetic spectrum with decreasing frequency is:<br />d) Gamma rays, X-rays, UV rays, Visible, Infrared rays, Microwaves, Radiowaves<br /><br />The electromagnetic spectrum is arranged in order of decreasing frequency and increasing wavelength. Gamma rays have the highest frequency and shortest wavelength, followed by X-rays, UV rays, visible light, infrared rays, microwaves, and radiowaves.<br /><br />28) The reason we cannot see light that falls on the blind spot is:<br />e) there are no photoreceptors (i.e., rods or cones) in the optic disk<br /><br />The blind spot is a region on the retina where the optic nerve exits the eye. This area lacks photoreceptor cells (rods and cones), which are responsible for detecting light and converting it into electrical signals. Therefore, any light that falls on the blind spot cannot be seen.<br /><br />29) The option that is not a natural source of radiation is:<br />d) Medical<br /><br />Cosmic rays, radon gases, and the human body are all natural sources of radiation. Medical radiation, on the other hand, is artificially generated through medical imaging techniques such as X-rays, CT scans, and radiation therapy.
