Exam 21: Unifying Concepts of Animal Structure and Function

Connective tissue is different from the other major tissue types in that ________.

One function of this organ system is ________.

Which animal generates (produces)body heat to warm itself?

Scenario The dune-burrowing spider Seothyra species lives in the Namib Desert on the southwestern coast of Africa. These spiders build silk-lined burrows with a sticky silk mat at the entrance to trap insect prey. While foraging during the day, the spider remains concealed in its burrow and shielded from direct sunlight when prey are not present. When insect prey become entangled in the sticky silk mat, the spider will run out of its burrow and capture the prey insects. During the day, environmental temperatures vary from 17 to 73°C (63-164°F). If a spider is forced to remain outside of its burrow, it shows signs of thermal stress at 49°C. When spiders are unrestrained, they spend more time waiting inside their burrows to keep their internal temperatures below 49°C, even when surface temperatures are above 65°C. In addition, spiders respond more quickly to prey stimuli during the hottest times of the day and capture prey in significantly less time when surface temperatures are above 49°C. The captured arthropods (prey)tend to succumb more quickly to hot surface temperatures; they are more lethargic and struggle less when captured at the high temperature ranges. -Based on the information in the paragraphs, spiders are ________.

What is true of a water molecule that is excreted by the urinary system?

What kind of connective tissue has a matrix that is strong and flexible?

Why does measuring oxygen consumption estimate how a Burmese python generates body heat?

In a multicellular organism, cellular exchange with the environment can only occur if ________.

A physiological response that takes place in many animals when they get too hot is ________.

During heat stroke, what mechanism is being disrupted?

In humans, goosebumps are a vestige of a mammalian adaptation related to ________.
