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.
Earthworms are hermaphrodites where each earthworm contains both male and female sex organs. The male and female sex organs can produce sperm and egg respectively in each earthworm. Although earthworms are hermaphrodites, most need a mate to reproduce. During mating, two worms line up inverted from each other so sperm can be exchanged. The earthworms each have two male openings and two sperm receptacles, which take in the sperm from another mate. The earthworms have a pair of ovaries that produce eggs. The clitellum will form a slime tube around it, which will fill with an albuminous fluid. The earthworm will move forward out of the slime tube. As the earthworm passes through the slime tube, the tube will pass over the female pore picking up eggs.
