Q: Mollusks, annelids, and arthropods are considered what? Read this paragraph and choose the correct option from the provided answers: Mollusks, annelids, and arthropods are protostomes. Echinoderms and chordates are deuterostomes. This distinction is important. Why does it matter? It shows that echinoderms are more closely related to chordates than are the other invertebrate phyla. This is not apparent based on other, more obvious traits. Choices: - protisines - detritivores - micelles - protostomes A:
protostomes

Q: What process involves the flow of heat from warmer objects to cooler objects? Read this paragraph and choose the correct option from the provided answers: Through the process of conduction, heat flows from warmer objects to cooler objects ( Figure below ). The lower mantle is heated directly by conduction from the core. In conduction , heat is transferred as atoms collide. Choices: - activation - convection - radiation - conduction A:
conduction

Q: Lymph capillaries collect fluid that leaks out of what? Read this paragraph and choose the correct option from the provided answers: Lymph capillaries collect fluid that leaks out from blood capillaries. The lymphatic vessels return the fluid to the cardiovascular system. Choices: - bladder - alveoli - lymph nodes - blood capillaries A:
blood capillaries

Q: The concentration of hydrogen ions in a solution is called? Read this paragraph and choose the correct option from the provided answers: The strength of acids and bases is determined by the concentration of ions they produce when dissolved in water. The concentration of hydrogen ions in a solution is called acidity. It is measured by pH. A neutral substance has a pH of 7. An acid has a pH lower than 7, and a base has a pH greater than 7. Choices: - alkalinity - alcohol - moisture - acidity A:
acidity
