Which event caused speciation of the finches of the Galapagos Islands in picture B? *
vampirchik [111]

Answer:

B. Geographic Isolation

Explanation:

Speciation is a biological process that allows the generation of new species through existing species. Through conditions imposed by the environment in which this species lives.

Speciation is usually caused by geographic isolation.

Geographic isolation occurs when a population of the same species is separated by some type of natural barrier, such as rivers or mountains. This causes the population to be divided in two and begin to face different environments and different environmental conditions. This causes each part of the population to adapt in different ways, leaving them so different from one another that it is no longer possible to say that the two populations belong to the same species.

Vinvika [58]

Answer:

Red blood.

Explanation:

Red blood is for oxygenated blood, while blue blood is for deoxygenated blood.

The blood in Isabelle's left ventricle would be red, in other words, oxygenated. The left ventricle has oxygenated blood because this blood was first in the right ventricle. Then, it went to the pulmonary arteries, which led the blood to the capillaries close to the alveoli in the lungs. In this area, the deoxygenated blood dropped the CO₂ and took O₂ becoming oxygenated blood. Now, this blood is color-coded red and will go to the pulmonary venules, then to the pulmonary vein, and from there, it will go to the left atrium. Lastly, it will go to the left ventricle to start the systemic circulation, which is the one that distributes the oxygenated blood in the body.
