The relationship between the lithosphere and the asthenosphere is that they both make up the earth's mantle. The asthenosphere lies right below the lithosphere.
Hope this helps!
Answer:
The cell wall
Explanation:
The cell wall exists to protect the cell, maintain its shape and regulate water uptake. The cell wall is much thicker than the cell membrane, providing an extra layer of protection. In plants, the cell wall is made of fibres of the polysaccharide cellulose, which is a structural carbohydrate.
This gives organisms such as plants much more structure - e.g. they can stand upright without the need for bones. However, they lack the same flexibility that animal cells have.
A jellyfish would die if it was placed in a freshwater lake. Salt water has more solutes than freshwater, so a freshwater environment would be hypotonic to a jellyfish's cells.
Answer:
2. ER protein
4. insulin
6. lysosomal enzyme
Explanation:
Ribosomes are the organelles which are associated with the synthesis of proteins in the cell as they provide the machinery and site for protein synthesis.
The ribosomes can be freely present in the cytosol or they are presently attached to the endoplasmic reticulum.
The free ribosomes are destined to produce proteins which are required by the same cell like the DNA polymerase enzyme and ribosomal protein but the attached ribosomes produce proteins which have to be transported through the cell-like insulin, and the lysosomal proteins.
Thus, 2,4 and 6 is correct.
