Answer 2

A spider web is formed by the fluid that is secreted by the (a) abdominal gland.

• Within spiders are ducts, through which the silk passes before leaving the spider.
• The silk is made up of the liquid proteins. When the liquid reaches the duct, water is extracted from the cells from the silk proteins and is turned into a solid fiber as it is forced through the acidic silk glands.
