Answer:

Arteries: carry the blood away from the heart to the body cells/tissues.

Capillaries:  the site for an exchange of substances between the blood and body cells.  

Veins: carry the blood towards the heart from the body cells/tissues.

Explanation:

The cardiovascular system has arteries, capillaries, and veins as the main blood vessels. The walls of arteries are mostly thick and therefore, their lumens are narrow. Thick walls allow them to withstand the higher blood pressure. The function of arteries is to carry the blood away from the heart to the body cells/tissues. They mostly carry oxygenated blood. However, pulmonary arteries are the exceptions that carry the deoxygenated blood.  

Walls in veins are thin. They have a wide lumen. Their function is to carry the blood towards the heart from the body cells/tissues. They mostly carry deoxygenated blood. However, pulmonary veins are the exceptions that carry the oxygenated blood to the heart.

Capillaries are the thin-walled blood vessels that serve as the site for an exchange of respiratory gases, nutrients, wastes and other substances between the blood and body cells.

Answer:

The three main types of blood vessels present in the cardiovascular system are capillaries, arteries and veins.

Capillaries - The main function of the capillary is the transport of oxygen and nutrients to the cells and tissues of the body. The connection of the branches of the arteries with the veins is done by capillaries.

Arteries: The blood from the heart needs to travel all over the body. This function is performed by the arteries. The oxygenated blood flows in the arteries.

Veins: The deoxygenated blood from the body needs to travel from the body to the heart. This function is preformed by veins.

8. How did the Grants test their hypothesis that differences in birds' songs can keep finches
Goshia [24]

Answer:

The correct answer is -

8. They played the songs of medium ground finches and cactus finches through a loudspeaker at different times, when individuals from both species were present, to see which species responded to each song.

9. Males only came to the loudspeaker when the song of their own species was being played.

Explanation:

To test the hypothesis that differences in finches song they sing keep these finches to breeding from other members of finches, Grant should play the different songs of both medium ground finches and cactus finches one by one in loudspeaker and see what members of finches respond on what song.

It will show that cactus fiches breed only on their songs and medium ground finches on their song if the hypothesis is true. Male of each species respond to their songs only and not on other song played on loudspeaker
