Answer is D. Light travels more slowly in Medium A than in Medium B because Medium A is dense.

When light travels from a medium of low refractive index to a medium of high refractive index, it slows down in the latter and bends towards the vertical. The extent to which the light ray bends is directly related to the medium's refractive index (or the optical density).

Lets understand the given passage.

A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.

The light bends more in medium A than medium B. Hence medium A is optical denser than medium B.

Two organisms have analogous structures. A student concluded that these organisms must have a common ancestor is the student cor

Answer:

The student is wrong, just because the analogous structures of any two organism may have the same structure or even have the some relation between there way of operation or functions.

Explanation:

Analogous Structures:

As the similarity between two or more different organisms structure or any organ does not means that they have same ancestors or have the common origin from which the evolve into two different species. Now analogous structures are very much similar in there structure physically, but two different organisms may use them for the same function, which is astonishing to see or observe in way different species.

For example:

As the structure of the flipper of a Dolphin has similarity with the phalanges of a human being and with the wings of the bat. As all of them functions for the basic need of movement or locomotion from one point to another. While, all the three species are very much different in there features and are not the same obviously.
