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.
Part of an earthworm's excretory system is directly connected to his digestive system, as the intestines pass waste through the anus and out of the worm.This poop is called castings, and it serves as a type of plant fertilizer. However, some of the waste is picked up by excretory cells and carried outward to the skin.n earthworm has a closed circulatory system that uses vessels to send blood through its body. There are five aortic arches throughout his body that serve as pumps. The dorsal vessels take blood from the back of his body to the front, and the ventral vessels take blood the other direction, from front to back.
