The iris controls the amount of light that is entering the pupil. When its dark out, the sphincter muscles on the iris ease to dilate the pupil, but when its light out, the sphincter muscles contract to constrict the opening of the pupil.

Which part of the eye is adjustable in accordance with the light conditions?
The pupil goes larger in the dark, and smaller in the light.
The is the colored part of the eye that narrows and widens to control the amount of light entering the eye?
The colored portion that regulates the amount of light in eye is called as iris. The hole through which light passes inside the posterior chamber is called as is called as pupil. The color of the iris changes as per color of the skin pigment. It has got circular muscles and radial muscles in it. In fight or flight responce, it is dilated through sympathetic nerve stimulation. In relaxed and stress free envirinment pupil is constricted via parasympathetic nerve stimulation.
What controls the amount of chyme entering that small intestine?
The pyloric sphincter regulates the entry of chyme into the duodenum.
What structure regulates the amount of light passing to the visual receptors of the eye?

How does bleed off flow control differ from meter in and meter out?
meter in: regulates the speed of the actuator by controling the amount of fluid entering in to the actuator. meter out: regulates the speed of the actuator by controling the amount of fluid leaving the actuator. bleed off: regulates the speed of the actuator by metering a part of the pump flow to the tank. Prof. Mahesh Chopade MIT College of Engineering, Pune
What Is the part of the eye that contracts and dilates to adjust the amount of light entering the pupil.?
IrisThe colored part of the eye which helps regulate the amount of light entering the eye. When there is bright light, the iris closes the pupil to let in less light. And when there is low light, the iris opens up the pupil to let in more lightLensFocuses light rays onto the retina. The lens is transparent, and can be replaced if necessary. Our lens deteriorates as we age, resulting in the need for reading glasses. Intraocular lenses are used to replace lenses clouded by cataracts.CorneaThe clear front window of the eye which transmits and focuses (i.e., sharpness or clarity) light into the eye. Corrective laser surgery reshapes the cornea, changing the focus.
