10 Questions
What was the significance of synthesizing urea from inorganic components?
It showed that biological systems follow the laws of nature
What is the role of enzymes in biological systems?
They increase the efficiency of biological systems
What is the main difference between adaptation and acclimation?
Adaptation is a genetic process, while acclimation is a physiological process
What is the term for an organism that can tolerate a wide range of temperatures?
Eurytherm
What is the significance of the Q10 value in biological systems?
It measures the rate of reaction faster than predicted by the Arrhenius equation
What is the main difference between poikilothermic and homeostatic organisms?
Homeostatic organisms maintain a steady internal environment, whereas poikilotherms do not.
What is the main function of the rete mirabile in fish?
To conserve heat within the fish's core
Which of the following is an example of a behavioral adaptation in poikilothermic animals?
The ability to regulate body temperature through behavior
Why do larger animals tend to be more resistant to heat loss than smaller animals?
Because they have a smaller surface area-to-volume ratio
What is the main advantage of countercurrent heat exchange mechanisms in aquatic animals?
They conserve heat within the animal's core
