Concept explainers
Introduction :
Arthropods have complex organ systems that allow them to live in a variety of habitats. Adaptations to several organ systems, like the respiratory system and the nervous system, have contributed to the development of these animals.
Answer to Problem 4A
Correct answer :
The correct answer is option (C) 3.
Explanation of Solution
Explanation/justification for the correct answer :
Option (C) 3. In most arthropods, cellular wastes are removed from the blood through malpighian tubules. Such tubules also help terrestrial arthropods retain water in their bodies in order to maintain a homeostatic water balance. Tubules are found in the abdomen in insects. Malpighian tubules are bound to an empty intestine containing the undigested food waste to be eliminated from the body. So, the correct answer is option (C).
Explanation for incorrect answer :
Option (A) 1. The structure represents compound eye. Most arthropods have a pair of large compound eyes. Each compound eye has many hexagonal facets which see a part of an image. It can detect smell, and movement of prey, mates or predators. So, this is an incorrect option.
Option (B) 2. This structure is the antennae. Antennae are long sensory structures that contain receptors for the senses of smell and touch. The antennae are attached to the head part of many arthropods. So, this is an incorrect answer.
Option (D) 4. This structure is the digestive tract. Arthropods have a complete one-way

- a. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involvedarrow_forwardIf you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C. Dose; Do not change dose D. Interval; Increase the interval between doses (give the drug less frequently) E. Interval; Decrease the interval between doses (give the drug more frequently) F. Interval; Do not change the intervalarrow_forwardWhat percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. Show the matharrow_forward
