adoni [48]

Answer:

Disruptive selection

Explanation:

According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.

From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.

According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.

The two graphs shown below represent data collected from the same lake
Natali [406]

Answer:

C. The trout population decreases as oxygen levels decrease.

Explanation:

We can see that the relationship between the number of trout and time passed is decreasing from the graph on the right because its line is decreasing. From the graph on the left, we can see that oxygen is decreasing as time goes on. Thus, we can interpret that the trout population decreases as oxygen levels also decrease; a proportional relationship.

The other options are incorrect because we can actually see that for...

A; the population of whitefish actually decreases as oxygen levels also decrease.

B; the population of carp actually increases significantly as sewage levels increase.

D; the walleye population actually also decreases overall as sewage levels increase.

Select all that apply Smaller groupings within a species are called _____.
galina1969 [7]

I'm afraid none of those is correct. The correct option would be subspecies. Subspecies are different variations, one could say, of a same organism.



Hope it helped,


Happy homework/ study/ exam!
