Answer:

c. They may evolve into two separate species as a result of disruptive selection

Explanation:

Disruptive selection is a type of natural selection wherein some extreme change in the surroundings favor two distinct phenotypes while trimming off the mean. Here, the environmental conditions favor more than one phenotype. In the given example, disruptive selection would favor the light-colored lizards in the sandy region while the dark-colored would be favored in rocky regions due to their respective survival success.

With time, these two populations would accumulate more variations and reproductive isolation would not allow them to interbreed and thereby two distinct species of lizards would evolve.

What are the sequence of steps that includes the image on the retina
jonny [76]

Answer: Light goes into the eye via the cornea, it then pass through the pupil, the lens, the vitreous humor and finally forms an image on the retina.

Explanation:

Light goes into the eye via the cornea. The cornea is a clear, dome-shaped surface that covers the front of the eye.

From the cornea, the light passes through the pupil. The pupil regulates the amount of light passing through.

From the pupil, , light hits the lens. The lens is the clear structure inside the eye. It focuses light rays onto the retina.

Subsequently, light passes through the vitreous humor. A clear, jelly-like substance that fills the center of the eye. It helps to keep the eye round in shape.

Finally, the light reaches the retina where the image is formed the image is usually inverted. The retina is a light-sensitive nerve layer that is situated at the back of the eye.

The main function of the optic nerve is to carry the signals to the visual cortex of the brain. The visual cortex turns the signals into images.
