Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Insects can be distinguished from spiders because insects have:
A
2 body sections
B
6 legs
C
8 legs
D
no wings
Explanation: 

Detailed explanation-1: -Insects have only six legs. Spiders, scorpions, mites, ticks, whip scorpions, and pseudoscorpions are all arachnids that can be found in Everglades National Park . Unlike insects, arachnids have eight legs and no antennae, and their body is divided into two main segments: a cephalothorax and abdomen.

Detailed explanation-2: -*Adult insects have six legs. *Insect bodies have three parts (head, thorax, abdomen). *Insects have one pair of antennae. *Insects have an exoskeleton.

Detailed explanation-3: -Colloquially, in the terrestrial world, they are things that an organism walks on. But the scientific definition of ‘legs’, for insects, relies on homology: many insects have six ‘legs’ because they all descend from a common ancestor, which had six legs.

Detailed explanation-4: -Yes. Some spiders have six legs, one pair of which is the chelicerae (spider legs). The other five pairs of spider legs are used for walking around on all fours like a normal spider; these are called pedipalpus or “palps”.
