Because you get most of the vitamin D for the sun and it can help or damage your skin.
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
When you are exposed to bright light, cells in the retina detect the stimulus and send it to the brain for processing. The brain commands the iris to constrict and decrease pupil size.
The structure that serves as a receptor in this system is Retina
<h3>How can we see the object?</h3>
Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.
The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.
These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.
Thus, Retina is the answer.

Answer:
Stage REM Sleep
Explanation:
According to the AASM (American Association for Sleep Medicine), the sleep has five stages. The first is the stage of wakefulness when you are starting to feel drowsy. Then the stage N1 is the transition into sleep: the breath becomes shallow, and the body doesn't move or just a little. In stage N2 the physiological function of the body start to decrease and is more difficult to wake up than the stage before. The next stage is the N3, which is the stage when is more difficult to wake up from all stages because is the deepest sleep, and in this stage, the movement of the eyes stops. The last stage is REM,(rapid eye movements), in this stage the brain is more active but the body is paralyzed.
