The salivary glands of the silkworm are located in the head region, specifically near the mouthpart. These glands are responsible for producing silk proteins, which the silkworm secretes to create its silk cocoon. There are typically two pairs of salivary glands: the anterior and posterior glands, each playing a role in silk production and digestion.
A 6-legged spider-like insect is distinguished from other arthropods by its body structure, which includes two body segments (cephalothorax and abdomen), eight legs, and usually silk-producing glands. This unique combination of features sets it apart from other arthropods like insects and crustaceans.
Silk in spiders is produced in special glands located in their abdomen. The silk glands contain liquid protein which solidifies as it is extruded through spinnerets located at the rear of the spider's abdomen, forming strands of silk.
Spinnerets are the silk-producing glands that spiders possess.
A six-legged spider-like insect is distinguished from other arthropods by its body structure, which includes a distinct head, thorax, and abdomen, as well as specialized mouthparts for feeding. Additionally, these insects have silk-producing glands that allow them to spin webs for catching prey and creating shelters.
Spinnerets
Caterpillars form their cocoons out of silk. They have silk glands near their mouths that weave the silk, which they then wrap around their body to form the cocoon.
False
Proteins =3 (This is the 100% right answer because it is in my science online textbook and the original one)
Spiders produce silk from their spinnerets located at the rear of their abdomen. They release silk through tiny spigots to spin webs for catching prey or building shelters. The type and complexity of the web vary by species and use.
I believe they have silk glands on their posterior that allows them to do that.
Wild silk worms exist all over the world, as below, except on the Antarctic continent and the extreme polar northern latitudes. Anyone who wants to cultivate silk worms can live in any state, because the commercial silk worms are entirely domesticated.
