Answer:

Option A

Explanation:

All four types of polysaccharides are homopolymers ie they are made up of repeating units of only one type of monomers.

Starch, glycogen and cellulose are made up of repeating monomeric units of glucose with the number of glucose units and the different linkage types different these molecules. E.g the linkage between glucose units in glycogen is alpha 1-4 linkages and in cellulose, we have glucose in beta 1-4 linkages.

In chitin, a derivative of glucose is present in repeating units, here, we have N-acetyl-D-glucosamine in beta 1-4 linkages.

What types of materials are expelled from cells during exocytosis?
alex41 [277]

Large molecules such as hormones materials are expelled from cells during exocytosis

<u>Explanation:</u>

The materials inside the cells are transferred to the outside of the cell and this manner is termed as  Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.

For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.

Answer:

Linked Genes Violate the Law of Independent Assortment. Although all of Mendel's pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other.
