The answer is a, true.

Usually, in arteries, the main function is to carry oxygenated blood and the blood with nutrients away from the heart to other organs for them to function. And veins, which carries deoxygenated blood and blood with waste materials from other organs back to the heart.

The only exception is for the pulmonary artery and vein. Pulmonary artery does carry blood away from the heart too, but it carries the deoxygenated blood that is used earlier back to the lungs for gas exchange. And after the gas exchange in lungs, where the blood would be filled with oxygen and waste are carried away, those blood would be transferred back to the heart through the pulmonary vein.

So, the answer should be true.

Answer from: Quest

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
