________ allow materials to be exchanged between the blood and tissues, ________ carry blood towards the heart, and ________ car
Anuta_ua [19.1K]

Answer:

b.  Capillaries; veins; arteries

Explanation:

Capillaries are the blood vessels with very thin walls. They serve as a site for an exchange of substances such as respiratory gases, nutrients, and toxins between the blood and the cells of the tissues. Veins are the blood vessels that mostly pick the deoxygenated blood from the body cells and deliver it to the heart for oxygenation. On the other hand, arteries are the blood vessels that mostly carry the oxygen-rich blood. They pick the oxygenated blood from the heart and deliver it to body cells. Therefore, veins carry blood towards the heart while arteries carry it away from the heart.

erastovalidia [21]

The correct answer is A. A burst of speciation

Adaptative radiation is part of evolution and occurs when a single organism or species diversify into a wide range of species (speciation), this process is called "adaptative" because the speciation occurs due to changes in the environment that make challenging survival usually due to the reduction of resources available and therefore organisms change to adapt to new conditions. Additionally, in adaptive radiation, the new organisms share traits with their common ancestor but also have different and unique traits. Considering this, it can be concluded adaptative radiation a burst of speciation.
