Multiply the numerators of the two fractions. Since the numerators are both 2, you can multiply 2 * 2 to get 4. 3. Multiply the denominators of the two fractions. Since the denominators are both 4, just multiply 4 * 4 to get 16. Your answer is a fraction comprised of the new numerator and the new denominator.
A: The pumping organs of the circulatory system are five aortic arches. Circulatory fluids travel from the arches through the ventral blood vessel to capillary beds in the body. The fluids then collect in the dorsal blood vessel and reenter the aortic arches.n the intestine, which extends over two-thirds of the body lenght, digestion and absorbsion take place. The gizzard is a muscular organ used to churn the food and then it moves onto the intestine where absorbtion of the food occurs. 8. Your dissection of the earthworm did not go beyond segment 32.
Earthworm. The earthworms' respiratory system is very different compared to other mammals, but the purpose is the same, get the oxygen and take out the carbon dioxide. Earthworms do not have lungs or gills like other mammals, but instead they breathe by using their moist skin.espiratory System. The respiratory system performs exchange between gases. The molecules of oxygen and carbon dioxide are exchanges, this process changes oxygen to carbon dioxide. Our respiratory system is responsible to clean out the bacteria or dust we breath in.
