Characteristics outlined below
Explanation:
Anthropods, though they generally possess exoskeleton, segmented bodies and joint appendages, are divided into four (4) groups:
- <em>Tracheata</em> (breath through channels in their bodies. E.g. insects)
- Chelicerata (More than four legs, one pir of chelicerae i.e. claw or pincer. E.g. Scorpions and spiders)
- <em>Crustaceans</em> (Have a large rigid exoskeletal, without a circulatory system. E.g. Shrimps, crabs)
- <em>Trilobite</em> (extinct three-headed/lobed marine species)
Answer:
The answer to your question is: density = 5 g/cm³
Explanation:
Data
Volume = v = 2 m³
mass = m = 1 x 10⁴ kg
Density = d = ? g/cm³
Formula
density = mass/volume
Volume
1 m³ ------------------- 1 000 000 cm³
2 m³ ------------------ x
x = (2 x 1 000 000) / 1
x = 2 000 000 cm³
Mass
1 kg ------------------ 1000 g
1 x 10⁴ kg ------------ x
x = (1 x 10⁴ x 1000) / 1
x = 10 000 000 g
density = (10 000 000) / 2 000 000
density = 5 g/cm³
