The extracellular matrix of animal cells . The extracellular matrix of animal cells . provides avenues for the exchange of DNA is a warehouse for the storage of extra lipids and carbohydrates protects and support cells is primarily a site of dead matter and waste materials

Protects and support cells

Explanation:

The extracellular matrix is a solution present within each cell and tissues which is composed of the extracellular material like the protein-collagen, polysaccharides and the water.

Each cell has this ECM in different proportion, topology and composition depending on the function and type of the cell. The ECM is constantly changing by the enzyme activities which depends on the stage of the cell is in. The Extracellular matrix is known to play a role in the protection and support the structure of the cell.

Thus, Protects and support cells is correct.

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
