Explanation:
Plant cells have what is perhaps the most complex outer coverings. Plant cell walls are made largely of cellulose which forms strong, highly rigid, almost indigestible coverings that protect the cell and gives it shape.
The correct answer to the question above is cytoskeleton. Microtubules, microfilaments, and intermediate filaments make up the cytoskeleton, which lies beneath the plasma membrane and provides support, movement, and shape for the cell. These structures definitely form cytoskeleton for the support and structure.
In the Claritin commercial, the man is laying in the grass with a
beagle puppy. The beagle is a breed of small hound that is similar to a larger
foxhound that has approximately
220 million scent receptors. This is the reason why they are employed as
detection dog and not as guard dogs for they are usually friendly dogs.
