_____ allow materials to be exchanged between the blood and tissues, _____ carry blood towards the heart, and _____ carry blood
likoan [24]

Capillaries; veins; arteries

Capillaries allow materials to be exchanged between the blood and tissues, veins carry blood towards the heart, and arteries carry blood away from the heart.

Capillaries are small blood vessels through which molecules such as oxygen and glucose enter the cells.  

Veins are tubes or blood vessels that transport blood toward the heart. Veins mostly transport deoxygenated blood towards the heart except the pulmonary and umbilical veins, which transports oxygenated blood toward heart.

Arteries are blood vessels that transport blood away from the heart to other parts of the body. Arteries have elastic walls and they are stronger and thicker than veins.

mixer [17]
Mulch<span>, a type of protective covering which is in direct contact with the ground, provides more protection than canopy cover. It can vary from straw, to compost, to wood chips, or saw dust. Spread evenly onto the ground, mulch helps to reduce water evaporation, control weeds, and enrich the soil. It is also significant in protecting soil where vegetation has not had ample time to establish itself. By absorbing the destructive forces of raindrops and wind, mulch reduces erosion until the the seedlings mature enough to provide their own protective cover. thats all I know</span>
