Answer:
Circulatory system remove waste from the cell and provide clean blood to the cell.
Explanation:
During cellular respiration, lungs inhale oxygen which stored in the alveoli. The red blood cells contains hemoglobin that carries deoxygenated blood containing carbondioxide from the cell in the veins to the heart and unload this carbondioxide gas in the alveoli of the lungs and load oxygenated blood having oxygen from the alveoli through capillaries in order to provide oxygen to the cells that is necessary for the survival of humans. Platelets are the type of cells that helps in blood clotting whereas white blood cells provides immunity against pathogens.
They need to break down the food and organisms inside of it before being able to use the nutrients in food.
One kind of rock forms when other types of rock are changed due to extreme high temperatures is "metamorphic".
<u>Explanation:
</u>
Rock cycle stands as geology's fundamental notion. This denotes transitions occurred in three primary rock kinds as: igneous, metamorphic, and sedimentary. When extreme increased temperature and pressures are exposed on rocks then a new kind of rock is formed after chemical and physical reformation named as "metamorphic".
Basically there are two major metamorphism: regional and contact. Population of rocks are resulted from regional or dynamo thermal metamorphism. They were highly exposed to tectonic forces and related with high temperatures and pressures. Each type of rock is altered by being pulled out of its conditions of equilibrium.
