Ecologists have studied the Galapagos islands for a long time because of the diversity of the populations they possess. It is th

ought that small colonies of finches emerged on each of these small islands, each small population carrying only certain alleles of the parent population. Over time, the emerging populations varied greatly from one another, leading to the development of new species. Which mechanism of speciation best describes this scenario?

B) founder effect, your welcome

The correct answer is - B) founder effect.

The founder effect represents the loss of genetic variation in a new population due to the small number of individuals from the larger population that have formed the new population.

The finches on the Galapagos Islands have developed unique characteristics in accordance to their environment. Because there were only very small number of individuals that settled each island, the genetic variation was not the same as while they were part of the larger populations.

Because of this, those small number of individuals starter to develop unique traits only on that single island, which can easily be seen in the shape of their beaks in accordance to the available food source.

neonofarm [45]

Given what we know, the three sentences in this question all describe the properties of oceanic crust.

<h3>What is the oceanic crust?</h3>
  • The oceanic crust is the outer layer of the earth, located at the bottom of the oceans.
  • It contains three layers, ordered by number.
  • During subduction, this remains the topmost crust.
  • It is formed by the solidification of magma.
  • The oceanic crust is known to be very dense.

Therefore, we can confirm that the sentences in the question describe oceanic crust given that this is the topmost crust during subduction, formed by the solidifying of magma, making it a much denser rock than the other forms of crust.

A swimmer sprints a short distance for a competition. The swimmer is not able to take in enough oxygen to make the ATP needed fo
Reptile [31]

When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.

Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.

Two ways in xylem is modified to carry out its function
Bess [88]
1. The cell wall has lignin (hard substance): to prevent the xylem vessel from collapsing and withstand high pressure.
2. The absence of protoplasm (nucleus + cytoplasm) and cross wall: to allow water to move through the lumen easily.

Hope it helped!
