Yes, this is correct!

Let's imagine two systems, one with 50 species and one with 4000. Both of them experience a draught and as a result 25 species of the first one die (that's quite likely) and 800 of the second population die out (more would not be very likely).
So the first one lost 50% of species and the second one 20% - that means that the second one, with greater biodiversity has a bigger stability:)

Would vision and audition be considered "higher senses” in non-human animals? Why or why not?

Dimas [21]

Answer:

Not necessarily

Explanation:

There are animals in which vision and audition are more specialized than in humans, while in other species this relation fails. For example, in predatory birds, the vision clarity surpassing human eyesight, since this sense is required for effective prey capture. Conversely, in the European mole (<em>Talpa europaea</em>), which is a mammal that lives mostly underground, the vision is seriously short-sighted. These are clear examples that "the function makes the organ", ie., phenotypic features such as vision and audition are selected in the course of evolution depending on the fitness that they confer to the species in particular environmental conditions.

Matings between individuals from the two populations of Rhagoletis produce hybrid flies that appear to be healthy and have norma

Mama L [17]

<h2>The correct answer is : C.</h2>

Explanation:

According to the question, mating between two populations of Rhagoletis produce hybrid flies.
This means that the two population is present in the same habitat or locality, hence they are capable of coming in contact with each other and mate. Hence, the answer cannot be Habitat Isolation.
Mating produces hybrid flies. This is possible when the gametes (egg and sperm) of the two different populations are capable of capable of coming close to each other and undergoing fusion (fertilization). Hence, there is no Mechanical Isolation.
The zygote formed by the above fertilization is capable of developing into healthy hybrid flies with normal life span. Hence, Pre-zygotic Isolation is absent.
But the hybrid flies formed are sterile and not fertile, that is, they are incapable of producing viable gametes which can undergo fertilization and produce a new offspring.Therefore, the eggs laid by the hybrid flies hatch less often. Hence, there is existence of Reduced hybrid fertility.
