Answer:

The correct answer is option 2. "Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano".

Explanation:

A seismometer is an equipment used by scientists to monitor ground's motion, including the earthquake activity that occurs beneath a volcano. These instruments are useful to predict if a volcanic eruption is imminent. By analyzing the length and strength of the ground's motion occurring during earthquake activity near a volcano, scientist could predict if an eruption is about to take place.

kmf Of the 40 specimens of bacteria in a dish,3 specimens have a certain trait. If 5 specimens are to be selected from the dish

almond37 [142]

Answer:

$\frac{C^{3}_1* C^{47}_4}{C^{40}_5}$

Explanation:

It is given that out of 40, total 5 specimen are selected.

Thus, the number of ways in which 5 specimens are selected from a given sample of 40 is given by

$C^{40}_{5}\\$

Number of specimen with certain trait is equal to 3.

Now, total 5 specimen are selected out of which one specimen is selected from the set of specimen that has certain trait (i.e out of 3) while the remaining four specimen will be selected from the rest $40-3=37$ specimen.

Thus, the probability of choosing only 1 of the 5 specimens with the trait is equal to

$\frac{C^{3}_1* C^{37}_4}{C^{40}_5}$

Sati [7]

<h2>Prezygotic barriers </h2>

Explanation:

Two potential prezygotic barriers that may be contributing to the divergence and speciation of these two populations of flycatchers are behavioral isolation and habitat isolation

A prezygotic reproductive barrier is a mechanism that prevents fertilization from occurring
Behavioral isolation means many species perform different mating rituals for reproduction,for example mating calls of both flycatchers may be different
Habitat isolation is a type of prezygotic barrier in which two species that could interbreed because the species live in different areas,here in this case flycatchers are living on two different islands and hence cannot mate which results into divergence of two different species

Evidence that would indicate that speciation has already occurred within the flycatcher populations is geographic patterns which resulted into allopatric speciation

Flycatchers are isolated from each other by geographical barriers because they are located on two different islands
As they are geographically isolated from each other speciation which occurs is allopatric
