Question

using the analogy of the immune system as a medieval castle, what would be the most accurate comparison to a deep cut in the skin that allows bacteria to enter the body? a catapult breaking through the outer stone wall. an enemy soldier swimming across the moat. a spy poisoning the castles water supply. a soldier inside the castle opening the gate for the enemy. the passage states that blood defends the body against infection andrepairs body tissues. if a person had a genetic condition that resulted in an extremely low production of both white blood cells (wbcs) and platelets, which overall bodily function would be most critically and immediately compromised? homeostasis (the bodys stable internal state), due to an inability to stop bleeding and a failure to fight off common, ever - present pathogens. digestion, because the lack of these cells would prevent nutrients from being absorbed into the plasma. circulation, because both wbcs and platelets are needed to maintain the fluid volume of the blood. oxygenation, because the immune system is necessary to keep the respiratory tract clear

Explanation:

1. In the immune - system - as - castle analogy, the skin is like the outer stone wall of the castle. A deep cut in the skin that allows bacteria to enter is similar to a catapult breaking through the outer stone wall, as it breaches the primary physical barrier.
2. White blood cells fight off pathogens and platelets are involved in blood - clotting. Low production of both would lead to an inability to stop bleeding and fight off common pathogens, thus severely compromising homeostasis.

Answer:

1. A. A catapult breaking through the outer stone wall.
2. A. Homeostasis (the body's stable internal state), due to an inability to stop bleeding and a failure to fight off common, ever - present pathogens.
