As the population density increases therefore we probably have an increase in birth rate, aslo less space becomes available to individuals and if competition increases that means we probably have an increase in fighting (contest competition) therefore there might be an increase in individuals dying. Therefore I would say the answer is (c) the increase in population density would cancel out the competition. Hope this helps :).
Answer:
The urinary system consists of the ureters, kidneys, bladder, and urethra, also known as the renal system or urinary tract. It performs several functions including:
1. Regulate blood volume and pressure: change the amount of water lost in urine, EPO (more bone marrow activates RBC) and Renin
2. Regulate concentrations of plasma ions: monitors potassium, sodium, and chloride ions lost through urine and calcium ion levels by calcitriol synthesis (osteoclast activity and prevents urinary loss)
3. Helps to regulate blood pH: monitor hydrogen ion loss and bicarbonate ions in urine
4. Conserve essential nutrients: preventing nutrient excretion when excreting agricultural wastes
5. Help to detoxify toxins in the liver
