The reason it must aim for the fish in a slightly different place than where the fish appears to be located is option D: Light waves are refracted as they travel from air to water.
What is the refraction about?Light slows down when it transitions from less dense air into more dense glass or water. The light ray changes direction as a result of the slowing of the light. Refraction is brought on by a change in the light's speed.
We know that when light tends to bends away from the normal when it reaches the air, which is why the pelican must dive in front of the horizontally oriented image of the fish because of the law of refraction.
So, The angle at which the light exits the water from the fish bends it away from the normal, giving the impression that the fish is closer to the surface.

A pelican hunts fish in the water. As the pelican flies above the water’s surface, why must it aim for the fish in a slightly different place than where the fish appears to be located?
answer choices
Light reflects off the fish, except for light of the wavelength the fish absorbs, making the fish hard to see.
Water absorbs most of the light, so not much light reaches the pelican’s eyes.
Energy from the ocean waves is transferred to the light waves.
Light waves are refracted as they travel from air to water.

If two species are able to interbreed but produce sterile hybrids, their speices integrity is maintained by _____.
A postzygotic barrier protects the species integrity of two species that can interbreed but produce sterile hybrids.
What is postzygotic barrier ?A mechanism that prevents reproduction after fertilization and zygote formation is known as a postzygotic barrier. In the case of hybrid inviability, a mating between two individuals produces a hybrid that does not survive past the embryonic stages.
While we waited for our regular hamsters to arrive, we learned a lot about the different types of barriers that can cause reproductive isolation prior to fertilization. Matings between our flying and non-flying hamsters result in fertilization and the formation of zygote. As a result, it appears that the gene pools of the two types of hamsters are not isolated prezygotically. Even if the two types of hamsters were able to mate and produce a zygote, that zygote would still have to mature to a reproductive age and produce progeny for the two hamsters to be simply variants of the same species.
Although prezygotic barriers did not cause speciation, a mechanism that occurs after zygote formation could still be isolating the gene pools of the two hamster populations. Postzygotic reproductive barriers form after the zygote has formed, reducing either the viability (the ability to avoid dying) or the reproductive capacity of the hybrid offspring. Postzygotic mechanisms such as hybrid zygote abnormality, hybrid infertility, and low hybrid viability may still distinguish flying hamsters from non-flying hamsters. Let us look into these possibilities further to see if our flying hamster is a new species.
