Question

Разделение клетки на две дочерние происходит на стадии 1)Телофазы 2)Профазы 3)Метафазы 4)Интерфазы Клетка с хромосомами на экваторе: 1)Находится в состоянии анофазы 2)Находится в состояние Метафазы 3)Начинает митотическое деление 4)Заканчивает митотическое деление

Answer 1

Первый вопрос вроде ответ 3,а ответ на  второй вопрос ответ 2

Answer 2

1) в телофазе веретена деления исчезает формируются новые клетки, в телофазу вся клетка делится. 2) Профазу хромосомы спирализуются. 3) хромосомы выстраиваются по экватору клетки во время метафазы. 4) удвоение днк происходит во время интерфазы. А к полюсам клетки расходятся во время анафазы.

Answer 3

Cell Division and the Stages of Mitosis

Cell division is a fundamental process in which a parent cell divides into two daughter cells. This process is crucial for growth, development, and the replacement of damaged or old cells in multicellular organisms. The division of a cell into two daughter cells occurs through a series of stages known as mitosis.

Mitosis is the process of cell division that ensures each daughter cell receives an identical set of chromosomes as the parent cell. Mitosis consists of several distinct stages, including prophase, metaphase, anaphase, and telophase. These stages ensure the proper separation and distribution of genetic material.

Stages of Mitosis

1. Prophase: During prophase, the chromatin in the nucleus condenses into visible chromosomes. The nuclear membrane disintegrates, and the mitotic spindle, composed of microtubules, begins to form. The centrosomes move to opposite poles of the cell, and the spindle fibers attach to the centromeres of the chromosomes.

2. Metaphase: In metaphase, the chromosomes align along the equator of the cell, forming a structure called the metaphase plate. The spindle fibers attach to the centromeres of the chromosomes, ensuring their proper alignment.

3. Anaphase: Anaphase is characterized by the separation of sister chromatids. The spindle fibers contract, pulling the sister chromatids apart and moving them towards opposite poles of the cell. This ensures that each daughter cell receives a complete set of chromosomes.

4. Telophase: Telophase marks the final stage of mitosis. The chromosomes reach the opposite poles of the cell, and new nuclear membranes begin to form around each set of chromosomes. The chromosomes begin to decondense, and the mitotic spindle disassembles. Finally, cytokinesis occurs, resulting in the physical separation of the two daughter cells.

Cell Division and Chromosomes at the Equator

Based on the information provided, it seems that the question is asking about the state of a cell with chromosomes at the equator during mitosis. At this stage, the cell is in metaphase. During metaphase, the chromosomes align along the equator of the cell, as mentioned earlier. This alignment ensures that the sister chromatids are properly separated and distributed to the daughter cells during anaphase.

To summarize, the division of a cell into two daughter cells occurs during mitosis, which consists of several stages: prophase, metaphase, anaphase, and telophase. The cell with chromosomes at the equator is in the metaphase stage of mitosis.

I hope this explanation clarifies the stages of cell division and their relation to the equator of the cell during mitosis. Let me know if you have any further questions!
