Spiders use their silk to build strong webs, to trap bugs, to save themselves from falling, to wrap their eggs safely, and even
11Alexandr11 [23.1K]

Answer:

The missing word is things.

However, the real question is how one material can serve so many purposes? That is what makes it possible for the spiders web to have a high "utility" value?

The answer is in how the spiders make the silk.

Explanation:

So it interesting to note that spiders do not make only one kind of silk. They vary depending on what purpose it's doing serve.

The most common type is Dragline Silk.

Dragline Silk: This contains spidroins. Spidroins fall under a category of a protein called scleroproteins. Because of its composition, a strand or fiber of Dragline has the same tensile strength as steel albeit more flexible. That is if one produced steel the diameter of a spider's silk, and compared both for strength, the silk will be stronger.

The spider produces Dragline silk in its silk glands where they are as viscous as a paste. From here is pulled out or extruded into lines of silk.

Other types of spider silk are:  

  1. Capture-spiral silk. Also known as the Flagelliform, they are used for securing lines of the web. They are adhesive, very elastic, and possess high tensile strength.  
  2. Tubiliform silk: They are also called Cylindriform. Its main use is for the protection of spider eggs. It is used to make a sac for which protects eggs. This type of silk is the toughest.
  3. Aciniform silk: For preserving fresh prey.  
  4. Minor-ampullate silk: This type is used by spiders for creating temporary support while they are spinning a web. Etc.

What statement most directly demonstrates a way that the geosphere is involved in the nitrogen cycle
Ulleksa [173]

B. bacteria that convert ammonia into nitrites and nitrates are found in the soil  

This statement best demonstrates a way that the geo-sphere is involved in the nitrogen cycle.

A nitrogen cycle is defined as the movement of nitrogen between the atmosphere, biosphere, and geo-sphere in different forms. Ammonia is converted to nitrates by nitrifying bacteria in the soil. Then the plants absorb these nitrates from the soil and use these to build up proteins.
