Explanation:

• Question 5: The bladder is the organ that collects and stores urine until it is ready to be excreted. This is a basic anatomical fact related to the urinary/excretory system.
• Question 6: The excretory system is important for survival because it removes waste products (such as urea, excess water, and salts) from the body. If these wastes accumulated, they could be toxic and disrupt normal bodily functions.
• Question 7: Homeostasis is the body's ability to maintain a stable internal environment. This includes regulating things like body temperature, pH levels, and fluid balance.
• Question 8: The liver helps the excretory system in several ways. It detoxifies harmful substances (e.g., converts ammonia, a toxic waste product, to urea which can be excreted by the kidneys). It also processes bilirubin (a breakdown product of red blood cells) and releases it into bile, which is then excreted from the body.

Answer:

• 5. The bladder.
• 6. It removes waste products that would be toxic if they accumulated in the body.
• 7. The body's ability to maintain a stable internal environment.
• 8. It detoxifies harmful substances (e.g., converts ammonia to urea) and processes bilirubin (releases it into bile for excretion).
