There are 13 species of finches living on the Galápagos Islands. According to the current scientific hypothesis,
these finches evolved from a species of finch that lived on
the mainland of South America. A few finches must have
become lost and landed on one of the islands. These
finches had to survive in a new environment. Different
pressures caused this new population of finches to evolve
differently from the original population. Eventually, the
populations became so different that they could no longer
produce offspring together.
Which of the following signal words best starts the
sentence that begins with "A few finches must
have"?
A. First
O B. Eventually
O C. Meanwhile
O D. Before

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
