Question

what are differences between xylem and phloem
systole and diastole
veins and arteries​

Answer 1

Answer:

Systole is the phase of the heart beat when the heart contracts and pumps blood into arteries. Diastole is the phase of the heart beat when the heart relaxes and allows the chamber to fill with blood

One of the major difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas, veins carry the deoxygenated blood to the heart.

Xylem transports only minerals and waters from the roots. Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant. ... Xylem is the dead tissues at maturity, but no cell contents. Phloem is the living tissue, but not with the nucleus
