The parts of unaided eye focus beam include cornea, aqueous humor, lens, vitreous humor, and retina. Light enters through the cornea, passes through the aqueous and vitreous humor, gets refracted by the lens, and ultimately forms an image on the retina for visual perception.
The answer is heterogeneous
The beam of light changes direction at the cornea (front surface of the eye), the lens (inside the eye), and the retina (back of the eye) to focus the image onto the retina for visual processing.

Tracts of axons in the central nervous system (CNS) are visible to the unaided eye and are called white matter. In the peripheral nervous system (PNS), nerve bundles are visible and may appear as "cables" connecting different parts of the body.
Homogeneous materials have a uniform composition and appearance throughout, meaning they typically look the same from any angle or perspective. Therefore, with the unaided eye, it is challenging to distinguish different parts within a homogeneous substance, as there are no visible variations in color, texture, or structure. Examples include solutions like saltwater or metals like gold, where the components are evenly distributed. In contrast, heterogeneous materials display distinct parts or phases that can be seen without magnification.

pupil
The beam of light entering your eye can change direction at the cornea, the lens, and the vitreous body. These structures help focus the light onto the retina at the back of the eye, where the images are formed.
Yes, you can with the unaided eye.
yes
Yes it is.
yes
it is an egg.
