The study of onion root tips is widely known for the clear appearance of the stages of mitosis since the chromosomes are large and are clearly visible. They are easily stained with the stainer and are visible clearly under the electron microscope. The phase of mitosis are
Interphase
Prophase
Metaphase
Anaphase
Telophase and
Cytokinesis
Each of these phases show the different stages in which the division of one cell into two daughter cells takes place. The cytokinesis is the final phase in the mitosis cell division. This is the part of cell division process during which the cytoplasm of the cell divides into two equal parts and forms into two daughter cells.
During the cytokinesis process, the spindle apparatus partitions and transports the duplicated chromatids and moves into the cytoplasm of the dividing daughter cells. In this process a dividing structure called the cell plate is formed to distinguish the daughter cells. This cell plate later grows into a double layered cell wall which then splits the parent cell into two separate cells.
Hence the option D is the right answer
Answer:
Mutation, migration, genetic drift, and natural selection are all processes that can directly affect gene frequencies in a population.
Explanation:
Answer:B. Primary consumer
Explanation:The reason why Its b because that primary comsumers are mostly herbivores or the primary comsumer is the first consumer to eat the producer.Hope it helps!
You are right, it is B because, endocrine glands, as part of the endocrine system, they regulate and maintain a constant equilibrium in our bodies, known as homeostasis.
