A line of indirect evidence of competition comes from the comparison between closely related species, whose population can be allopatric (geographically separated) or sympatric (geographically superimposed). In some cases, the allopatric populations of these species are morphologically similar and use similar resources. On the other hand, sympatric population, which are supposed to compete for resources, have body structures and use different resources. The displacement of characters is the tendency to have more divergent characteristics in sympatric populations of two species than in allopatric populations of the same two species.

An example of character displacement is the variation in size between populations of galapagos finches. Some of its populations are allopatric ( they live separately) and others are sympatric ( they live together). Peak size distributions they vary according to whether they are sympatric or allopatric.  They look more alike when they are allopathic than when they are sympatric. That is, the peak size character moves when species enter competition.

Which statements explain the gas exchange that happens at the alveoli? Check all that apply.
Arturiano [62]

Answer: B, C, E

Explanation:

We breathe in oxygen, which travels to the alveoli in our lungs. The alveoli "gives" oxygen to the capillaries, which carry blood. The capillaries "give" its carbon dioxide (which is what oxygen becomes when used by our body) to the alveoli. The carbon dioxide travel back out when we exhale. Although, the air we breathe out has some oxygen content.

Where does the sedimentary rock chalk form? from the precipitation of minerals in shallow marine environments by the lithificati
Katarina [22]

The correct answer is an accumulation of microorganisms in deep marine environments.

Chalk rock refers to a pure form of limestone produced in tropical and warm seas about 100 million years ago in the Cretaceous period. The microscopic marine algae known as coccoliths thrived in the ancient seas. Their shells were comprised of calcite. With the death of the algae, their bodies sunk to the floor of the sea and sediment of chalk got deposited.

Over many years layers of chalk sediment got deposited and resulted in compaction of loose sediment into solid chalk rock.
