Answer:

Proteins and polysaccharides.

Explanation:

Proteoglycans are heavily glycosylated proteins. These proteoglycans are present in the extracellular matrix of the animal cells and acts as a lubricant for the cells.

Proteoglycans are proteins that are covalently bonded with muco polysaccharidse. Proteoglycans are formed by the bonding between proteins and carbohydrates ( polysaccharides). Proteoglycans can combine with collagen to form cartilage and may affect the stability of a protein.

Thus, the correct answer is option (E).

love history [14]

Answer:

Eukaryotic cells are plants, animals, protists, fungi. Their genetic material is organized in chromosomes. Golgi apparatus, Mitochondria, Ribosomes, Nucleus are parts of Eukaryotic Cells.

Animals such as cats and dogs have eukaryotic cells.

Plants such as apple trees have eukaryotic cells.

Fungi such as mushrooms have eukaryotic cells.

Protists such as amoeba and paramecium have eukaryotic cells.

Insects have eukaryotic cells.

Humans are composed entirely of eukaryotic cells. Related Links: Examples.

Explanation:

Bacterial strains, especially Actinomycetes have been used in biotech production and drug discovery for years. Genetic methods now open the field of combinatorial biosynthesis that has improved impressingly in the past couple of years. Also, the productivity of yeast and other fungi in a variety of different processes has improved significantly since genetic methods have been introduced. In addition, a number of recent works considerably widens the potential of plant biotechnology. This review covers examples describing the use of prokaryotic cells and plant cells in biotech production.

Hope this helps! ^^
