Answer:
a. a plant cell undergoing cytokinesis
Explanation:
Cytokinesis is the process where the cytoplasm divides after mitosis to form two different daughter cells from the parent cell. Animal cell divides by just a cleavage formation. Plant cells have an additional step of formation of cell plate because they have cell wall.
At the end of anaphase and beginning of telophase when the two new daughter nuclei have just formed, cell plat formation begins. Secretory vesicles from golgi body come at equator of the dividing parent cell. These vesicles release all the materials required for cell wall formation. The materials start to form the cell plate which moves outwards till it reaches the division site of parent cell wall. Slowly cell wall arises from cell plate and cytokinesis occurs giving rise to new plant cells.
Answer: C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.
Explanation:
Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation.
