Answer:
7. Urinary tract infections don't always cause signs and symptoms, but when they do they may include: A strong, persistent urge to urinate. A burning sensation when urinating. Passing frequent, small amounts of urine.
8.Living things excrete. Excretion is the removal from the body of waste products which result from normal life processes. Waste products such as carbon dioxide must be removed. If they are allowed to accumulate they cause poisoning which slows down vital chemical reactions.
9Excretion is the process of removal of waste products whereas excretory organs are the organs through which excretion occurs. The process of discharging the undigested food from the animal's body is called egestion.
