Answer:
C. The songs will become more similar to each other.
Explanation:
To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.
One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.
So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.
The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.
Perlemoen is reasonably
easy to take available of the ocean and do not really required huge and
expensive equipment. The poachers take out millions of rands worth of Perlemoen
with relatively simple and cheap equipment such as wet suites, googles and
flippers. The most expensive equipment they use are their boats and vehicles. In
comparison with the lucrative industry the costs of poaching are low. Perlemoen
are often the smaller, younger abalone of the species that are taken because
they are quite simply and easier to harvest.
1.
The younger perlemoen are found closer to the
shoreline and often bunched together and they can get a whole whack of them at
one spot.
2.
The strandlopers harvested the perlemoen from
the rocks during low tide without the need for diving.

<span>In grafting, the plant with desired root system is called the <u>rootstock</u>, and the portion of the plant with the buds is called the <u>scion</u>.
The grafting is a horticultural technique in which parts from two or more plants are joined together to grow as a one single plant.
Rootstock is the plant selected for its roots because it can provide different properties, such as fruit size, or because it is resistant to drought or diseases.
Scion is the plant selected for its leaves, flowers, fruits or stems.

The endocrine gland that primarily controls the body's normal temperature as well as having it set to a homeostatic set point of 37 degrees Celsius is the hypothalamus, specifically, the anterior hypothalamus which primarily functions as a thermoregulator.
