Answer:
The Geographic barrier would have led to speciation in the finches which started from the founder effect where the finches were brought to other areas of the Galapagos. They were separated geographically so they could not mate with each other. Over time, evolution occurs through natural selection and genetic drift. This leads to the population being so different so they have reproductive barriers and can no longer interbreed. They become different species.

Answer:
A mass of nutrients enters a stomach full of strong, hydrochloric acid. The acid gets rid of all of the waste material, which is then expelled.
Explanation:
I would say D. small intestine
If you want an explanation, here it is
After leaving the stomach, water is absorbed mostly in the early segments of the
small intestine, the duodenum, and the jejunum. A small portion of all water absorption occurs in the stomach and the colon: the small intestine absorbs 6.5L/day, whereas the colon absorbs 1.3L/day.
Species A and B would be the most similar because there is only one mutation between the two of them located in the first codon.
Answer:
circulatory and respiratory
Explanation:
The body system of Birds possesses a higher arrangement of organs to perform a particular function. The organs form a system which includes the organs and associated structures.
When the biologist observed the shortage of the dissolved oxygen and increase in the level of dissolved carbon dioxide, this could be the result of the failure of the circulatory system which supplies these gases on the body and the associated respiratory system which helps in the exchange of these gases with the atmosphere.
Thus, circulatory and respiratory is the correct answer.
