10 Questions
Which environment has a higher heat capacity?
Living in water
Which statement about gas exchange is accurate for aquatic animals?
Less oxygen available, higher density and viscosity make it more energy-consuming to move water over a respiratory surface
What facilitates reproduction for aquatic organisms?
Flow facilitates reproduction by preventing gametes from drying out
What is a mechanism to reduce water loss for organisms living on land?
Production of concentrated urine through loop of Henle
What makes gas exchange relatively easier for air-breathing animals?
Relatively high oxygen content, lower density, and viscosity of air
What type of sensory receptor is involved in detecting small molecules for smell and taste?
Chemoreceptors
What is the function of the tympanal organ in insects?
Detect waves of pressure
What is the evolutionary origin of vertebrate middle ear bones?
Evolved from parts of the jaw
What happens to the eyes during the transition from water to air for animals?
They triple in size
How does surface area change in relation to volume as an organism's size increases?
Surface area decreases exponentially with volume
This quiz explores the unique characteristics of living in a water-based environment, including the stability of temperatures, metabolic waste removal, and reproductive facilitation. It also covers the physical properties of water, such as its density, viscosity, and heat capacity.
