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:
- 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.
- 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.
- Aciniform silk: For preserving fresh prey.
- Minor-ampullate silk: This type is used by spiders for creating temporary support while they are spinning a web. Etc.

Answer:Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.
Option (A) lining the straw is correct.
<h3>What is the anatomy of Earthworm?</h3>
- An earthworm is a terrestrial invertebrate and a member of the phylum Annelida.
- They have a tube-within-a-tube body structure, corresponding external and internal segmentation, and typically include setae on each segment.
- They can be found wherever the soil, water, and temperature permit.
- The body of an earthworm is composed of a digestive tube and a thick cylindrical muscular tube that forms the body.
- The body is divided into segments, and furrows on the surface of the body serve as markers for the segment boundaries.
- The top of the first segment, which encloses the mouth, is a lobe made of muscle and flesh.

All cells as we can say they work through their proteins. The work of proteins is being characterized by their sub-atomic capacity, contribution to a specific natural process and limitation inside. Segments of protein work which are being characterized by the correct synthesis, adaptation of proteins and structure which are being scrambled in the DNA area which is another name is called locus encoding the protein.
New proteins are being produced by the procedure of protein combined with organic cells, which are adjusted by the loss of protein cell through corruption. The RNA which is duplicated in protein hereditary data is encoded in DNA atom which is being created in the core known as RNA or mRNA. mRNA encodes data which is for solitary protein and is considered little in estimate by contrasted with DNA atom. This makes work easier for mRNA particles to leave the core passing through some small openings called atomic pores.
It leaves the core and goes straight to the cytoplasm. mRNA interferes with cell structure referred to as ribosome and fills in as cells contrasting agent within the procedure of protein union. Ribosome comprises of ribosome RNA particles or rRNA and proteins which are sorted out into two subunits.
When a small subunit is being accused of tRNA and corrosive amino acid methionine experiences mRNA which begins to begin flag.
When beginning succession AUG is found then the codon for corrosive amino methionine where substantial subunits join the little one to frame and hole ribosome where now protein amalgamation starts.
Following the codon downstream of AUG codon, the elongation of tRNA and amino corrosive enter to the ribosome. tRNA with wrong amino corrosive and wrong anticodon enters ribosome it is rejected because it can not base pair with mRNA.
The ribosome then propels on triplet and amino corrosive and tRNA enters the ribosome and method is then rehashed. In the termination, the ribosome achieves all the stop codons. Post-translation modification alludes to the covalent and leads to large enzymes change of proteins following biosynthesis of protein PTM happens in any progression within the life cycle of protein.
Protein in PTMs can be reversed depending upon the idea of change for example kinases phosphorylate of protein at a certain amino corrosive side chains phosphatases hydrolyzes phosphate where they gather and expel it from protein.
