A corn cob consists of three main parts: the husk, the kernels, and the cob itself. The husk protects the kernels and helps retain moisture. The kernels are the edible part of the corn and contain nutrients. The cob provides structure and support for the kernels to grow. Together, these parts work to protect, nourish, and support the growth of the corn.
Do you mean "spiders that make cobwebs"? Do you mean "poisonous" (like hemlock tea) or venomous (like cobra venom)? The word "cob" in "cobweb" just meant "spider." So a cobweb is just a spider web. Not all spiders are venomous. No spiders are known to be poisonous. Since black widows make webs, some "cob spiders" are highly venomous.
Simple: A dust web is made of particles of dust and dirt and other things such as leaves, just natural things. A spider web however, is made out of a special kind of silk that most spiders naturally produce and use to create/spin their webs.
it is a horse when you get horses with brown bodies and black mane and tails then that horse is therefore bay so it would be the breed of horse which is "cob" so it is a cob that has a brown body and a black mane and tail.
When you eat corn on the cob, the part you eat are the kernels of corn. The cob is the inedible fibrous structure to which the kernels are attached before you eat them.
