Question

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.1. Based on the information in the paragraphs, spiders are ______.a. endothermsb. ectothermsc. sometimes ectotherms and sometimes endothermsd. neither ectotherms nor endotherms2. In animals, individual cells are grouped into _____.a. organismsb. organsc. organ systemsd. tissues3. A main function of most types of epithelial tissue is ______.a. supportb. absorptionc. sensationd. covering surfaces4. Reabsorption is the movement of substances from the ______ to the ______a. blood... filtrateb. kidney... urinary bladderc. blood... nephrond. filtrate... blood5.In humans, goosebumps are a vestige of a mammalian adaptation related to ______.a. thermoregulationb. water conservationc. positive feedbackd. osmoregulation

Answer 1

spiders are. generally ectotherms.Their internal temperature depends on external temperature transfer.They are also poikilothermic because the body temperature varies with that of the external environment.,

In animals, individual cells are grouped into tissues. e,g Blood. The tissues gives rise to organs.

A main function of most types of epithelial tissue is covering surfaces.They line major all hollow surfaces, and covering body surfaces.

Resorption id the movement of fluid from the glomerular filtrate back into the blood. Ions, glucose,and other escaped metabolites are returned to the blood stream.

In humans, goosebumps are a vestige of a mammalian adaptation to thermoregulation. This is a thermoregulatory mechanism to regulate the body temperature,Goosebumps emits heat, to turn the moisture from the skin to vapour. This evaporate to release this moisture, which cools the body.
