Exam 40: Basic Principles of Animal Form and Function

In mammals this response is known as fever, but it is known to raise body temperature in other bacterially infected animals, including lizards, fishes, and cockroaches.

In a multicellular animal, the circulatory system exchanges materials with the external environment using specialized exchange surfaces. Which of the following is not an example of such an exchange surface?

Which of the following animals uses the largest percentage of its energy budget for homeostatic regulation?

An example of a connective tissue is the

Fibroblasts secrete

Blood is best classified as connective tissue because

The specialized structures of complex animals have evolved because

An example of effectors' roles in homeostatic responses is observable when

Of the following choices, the epithelium with the shortest diffusion distance is

An exchange surface in direct contact with the external environment is found in the

Multicellular organisms must keep their cells awash in an "internal pond" because

Seasonal changes in snake activity are due to the fact that the snake

A matrix of connective tissue is apparent in

An example of a properly functioning homeostatic control system is seen when

-Imagine that you are a biologist who is attempting to get an accurate measure of an animal's basal metabolic rate. The best time to measure the metabolic rate is when the animal

Panting by an overheated dog achieves cooling by

"Winter acclimatization" in cold-zone mammals can include

The transfer of heat from arterial to venous blood is seen in the Canada Goose. This type of thermoregulation is called

Use the following information to answer the next few questions. You just bought a freshwater tropical fish for your new aquarium. Once you arrive home, you fill the aquarium with cold, dechlorinated water and plug in the filter and heater. You immediately release the fish from his bag of warm water into the cold water of the aquarium and give him some food. After one hour, you notice the fish has lost its vibrant colouration and isn't swimming very much. After a few hours, you find the fish dead. -Which of the following physiological process(es)could have lead to the death of the fish? I. decrease in enzyme-mediated reactions II. increased rigidity in exchange membranes III. non-shivering thermogenesis
