Note the microvilli, which can be seen in the background, as tiny rounded structures that are approximately 0.15 microns in diameter. These microvilli cover the surface of each intestinal epithelial cell. The Giardia's ventral adhesive disk resembles a suction cup, where overlapping microtubules in the cytoplasm form a number-6-shaped figure. The edge of the suction cup, called the ventrolateral flange, partially encircles the adhesive disk and is absent posteriorly where a ventral pair of flagella emerges from above, dorsal to the disk. Giardia muris has four pairs of flagella that are responsible for the organism's motility. The adhesive disk facilitates adherence to the intestinal surface. | June 9, 2012 | {

With both his hands occupied by the cart, it would have been very difficult to open a door while exiting the store, and avoid its closure, had the portal not been electronically controlled with an electric eye.

You'll note that a number of its legs are missing. However, these appendages may easily be detached if grasped by an enemy, and will continue to wriggle, in order to distract predators. See PHIL 9824, and 9825 for two additional views of this animal. Each segment of a centipede's body possesses a single pair of legs. Emanating from the head is a pair of sensorial antennae, and its three pairs of mouthparts, consisting of paired mandibulae with teeth, maxillae, and palps. Located behind its head, this arthropod's first pair of legs has evolved into a pair of fangs. Although a rare occurrence, when it does bite its victims, the centipede ejects its venom, which is not generally toxic, although it may cause extreme pain to humans. | June 9, 2012 | {

Although some disease organisms have been recovered from bedbugs under laboratory conditions, none have been shown to be transmitted by bedbugs outside of the laboratory.The common bedbug C. lectularius is a wingless, red-brown, blood-sucking insect that grows up to 7 mm in length and has a lifespan from 4 months up to 1 year. Bedbugs hide in cracks and crevices in beds, wooden furniture, floors, and walls during the daytime and emerge at night to feed on their preferred host, humans. | June 9, 2012 | {

Due to the nature of the act of pushing the cart, had there have been a door with which to contend, the opening, and subsequent avoidance of its closure would have made exiting the store more difficult. However, the automatic, electronic eye-controlled door facilitated the exiting of the store, reducing a patron's need to negotiate another portal. Widely used, 'no-touch' automatic doors accommodate all types of users, including the mobility-challenged, as well as those whose hands are filled with purchases. Simple, and in common use, the wide automatic door is an excellent example of Universal Design. Other facilities should, where possible, consider this option. | June 9, 2012 | {

Bedbugs are not vectors in nature of any known human disease. Although some disease organisms have been recovered from bedbugs under laboratory conditions, none have been shown to be transmitted by bedbugs outside of the laboratory.The common bedbug is found worldwide. Infestations are common in the developing world, occurring in settings of unsanitary living conditions and severe crowding. In North America and Western Europe, bedbug infestations became rare during the second half of the 20th century and have been viewed as a condition that occurs in travelers returning from developing countries. However, anecdotal reports suggest that bedbugs are increasingly common in the United States, Canada, and the United Kingdom. | June 9, 2012 | {
