Exam 21: Unifying Concepts of Animal Structure and Function

Which one of the following types of tissue stores fat in the body?

Use the following information to answer the following question(s). The dune-burrowing spider Seothyra sp. 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. During the day, environmental temperatures vary from 17 to 73°C (63-164°F). If a spider is prevented from retreating into its burrow, it shows signs of thermal stress at 49°C, whereas unrestrained spiders continue to forage at temperatures 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 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. -When foraging spiders are too hot,they retreat into their burrows.What type of feedback system does this indicate?

Which process describes the forcing of water and other small molecules from the blood into a kidney tubule?

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