Insects have six legs and two antennae, and their body is made up of three main regions: head, thorax, and abdomen. They have an exoskeleton that contains sense organs for sensing light, sound, temperature, wind pressure, and smell. Insects typically have four separate life stages: egg, larvae or nymph, pupa, and adult. Insects are cold blooded and do not have lungs, but many insects can fly and most have compound eyes. Insects are incredibly adaptable creatures and have evolved to live successfully in most environments on earth, including deserts and even the Antarctic. The only place where insects are not commonly found is in the oceans. Insects pollinate flowers and crops and produce honey, wax, silk, and other products. However, some species that bite, sting, destroy crops, and carry disease may be considered pests to people and animals.
Millipedes, however, are commonly seen in the park, and fortunately, unlike centipedes, millipedes do not bite or sting. Millipedes are even longer and thinner than centipedes and have two pairs of legs per segment. Despite "milli" in their name, no millipede has 1,000 legs, but common species have anywhere from 36 to 400 legs. Millipedes move much more slowly than centipedes because their legs are tiny in comparison to centipede legs. Because of their lack of speed and inability to bite or sting, a millipede's primary defense mechanism is to curl into a tight coil, thereby protecting their delicate legs inside their exterior body armor.
Professor Elgar points out that the mutation for paler skin may actually have been an advantage as humans moved out of Africa into northern latitudes, where sunlight is less intense.Because lighter skin improves the absorption of sunlight, it would have enhanced the production of vitamin D by the body in these countries.
Rapid response from Army and the Defence Science and Technology Group to threats from IEDs is one example where Australia has taken prompt and innovative action to develop new tactics and technology. This work has not only advantaged Australian forces, but also our allies. For example, L3Harris Micreo and other industry partners have produced more than 200,000 award winning Redwing IED detection devices for the Afghanistan National Defense and Security Forces.
JP9347 Joint Data Networks will upgrade Link 16, Link 22 and advanced Common Data Link functionality across several platforms to enhance ADF operations and to ensure critical systems integration within joint and multinational task groups.
Project Land 200 Battlefield Command System is delivering a software Battlefield Management System (BMS) and a mobile secure tactical radio communications network for Land Forces. A digitised Battlefield Command System is key to conducting operations on the modern battlefield, where paper-based and voice radio systems are no longer adequate. 2b1af7f3a8
