Answer:

Keratin.

Explanation:

Skin acts as the most important immune organ of the body. Skin provides the first line of defense against the pathogen. Skin consist of different enzymes, proteins and chemical factors.

Keratin is one of the important protein present in the skin. Keratin provides the toughness and rigidity to the skin. The main function of the keratin is to prevent the skin to soak the moisture and protects the skin from excess water.

Thus, the answer is keratin.

One way in which the anabolism of pyrimidine nucleotides differs from that of purine nucleotides is that?
sattari [20]

Purine rings are attached to ribose phosphate as they are generated, but pyrimidine rings must first be constructed before being connected to the compound.

What are purine and pyrimidine nucleotides?

  • Major energy carriers, components of nucleic acids, and starting points for the creation of nucleotide cofactors like NAD and SAM are purine and pyrimidine nucleotides. Despite the obvious significance of these molecules, there is still much we don't know about how plants make and use these nucleotides.
  • Furthermore, only a small portion of the research in this field has included genetic analysis to determine the function(s) of particular enzymes. Nucleotide synthesis in plant cells follows similar processes to those in animal and microbial cells.
  • Purine and pyrimidine synthesis pathways are comparable and distinct from one another. The following are some similarities: Both bases need glutamine amide to be formed, and the "core" of the purine and pyrimidine bases that must be created includes an amino acid.

Explain why the Linnaean system has changed over time
Anna35 [415]
The linnaeus(L) published a system for classifying living things, in today's worlds its the modern classification system.  The L divides nature into three kingdoms, animal, vegetable(or plant), and minerals. (more smaller parts) As time pasted, and knowledge increased, other scientist added to the linnaeus original system.

So changes were made to update it from time to time.

What would be the most likely outcome for plants in earth if glucose molecules in cellulose were not arranged in an alternating
Lelechka [254]

Explanation:

The plants  would not retain their shapes.

Carbohydrates molecules that supply energy and provide support consist mainly of sugars or starches in long chains and rings to form monosaccharide monomers. Inclusive of monosaccharides, disaccharides and polysaccharides (which describes the type of bonding and the degree of complexity of the polymers), their basic makeup comprises C, H, O -with many polar OH groups.

Many long chain polysaccharides are made up of glucose joined by regular 1-4 glycosidic bonds used as energy storage (produced through phtosynthesis) and used for ATP synthesis via respiration, ethyl alcohol fermentation and lactic acid fermentation. Plants are mostly comprised of structural units cellulose and lignin. However, cellulose is their main structural polysaccharide, found within cell walls.

It is made up of special β, 1-4 glycosidic bonds, which give structural polysaccharides their rigid, strong structure; cellulose is not water-soluble and is highly stable. However, if these alternating bonds aren't present, the plants would lose their main structural support, which allows larger plants, and trees to grow upwards towards sunlight despite their mass.  When arranged in α 1-4 glycosidic bonds these molecules are water-soluble; water would be able to flow readily out of the plant tissue. Thus the plant cells and tissue, would not retain their shapes and may be limited in their potential height without structural support.
