Cell division is characterized by two important processes called the karyokinesis followed by the cytokinesis. Karyokinesis refers to the division of the nucleus which is followed by the division of the cytoplasm called the cytokinesis. In animal cells, it is by the formation of a cleavage furrow and in plant cells it is by the formation of a cell plate. Cytokinesis results in the formation of two daughter cells. If the cells are treated with chemicals that block cytokinesis, the seperation of cells is not possible leading to the formation of abnormally large sized cells, each containing two nuclei or sometimes can be multinucleated.

Question 26.
B. deposition
Question 21.
Erosion is a destructive force because they disassemble landforms and ultimately destroy the features. Kind of like cultural traits/aspects being diminished. Whereas, deposition is a constructive force because the depositing of sediments can literally form entire landforms- like sand dunes. It takes bits by bits or sediment by sediment to build an entire structure.
