Neco Model Questions Vol1 2018 Biology Question 30
Practice objective / multiple choice question 30 from the 2018 Neco Model Questions Vol1 Biology examination.
Two desert rodents are compared for water‑conservation ability. Both ingest \(200\) mL of water per day and produce \(30\) mOsm of metabolic waste daily. Species A excretes urine with an osmolarity of \(1200\) mOsm L⁻¹ at a volume of \(30\) mL per day. Species B excretes urine with an osmolarity of \(800\) mOsm L⁻¹ at a volume of \(45\) mL per day. Assuming urine is the only route of water loss, which species retains more net water and is therefore better adapted to arid conditions?
