Metaphase: In this stage, the chromosomes align at the cell\u2019s equator, forming a single plane known as the metaphase plate. The spindle fibers attach to the centromeres of each chromosome, ensuring they are correctly positioned for the subsequent separation.<\/p>\n 3. Anaphase: During anaphase, the centromere holding the sister chromatids together splits, and the spindle fibers shorten. As a result, the sister chromatids are pulled apart towards opposite poles of the cell. Once separated, each chromatid is considered an individual chromosome.<\/p>\n 4. Telophase: Telophase is the final stage of mitosis. In this stage, the chromosomes reach opposite ends of the cell and start to decondense back into chromatin. The nuclear envelope reforms around each set of chromosomes, creating two distinct nuclei. Meanwhile, the mitotic spindle breaks down, and the cell prepares for cytokinesis.<\/p>\n <\/p>\n Question 8. Structure of a Neuron:<\/p>\n <\/p>\n Question 9. Procedure:<\/p>\n Results: During the 24-hour period, the germinating seeds in Container A undergo cellular respiration, which involves the breakdown of glucose to produce energy in the form of ATP (adenosine triphosphate). This process releases heat as a byproduct. On the other hand, the non-germinating seeds in Container B do not respire actively and therefore do not release heat to the same extent.<\/p>\n As a result, you would expect to see that the temperature inside Container A, containing the germinating seeds, is higher than the temperature inside Container B which has non-germinating seeds. This difference in temperature demonstrates that heat is indeed released during respiration, confirming the exothermic nature of this cellular process.<\/p>\n Part – B (Marks 10)<\/span><\/p>\n Instructions:<\/span><\/p>\n Question 1. <\/p>\n Question 2.

\nWhat will happen if there is no mucus in the Oesophagus?

\nExplain the various stages of Mitosis.
\nAnswer:
\nMitosis is the process of cell division that ensures the equal distribution of replicated chromosomes to two daughter cells. It consists of several distinct stages, each crucial for the accurate separation of genetic material. The stages of mitosis are as follows:
\n1. Prophase: Prophase marks the beginning of mitosis. During this stage, the chromatin (a complex of DNA ami proteins) condenses and becomes visible as individual chromosomes. Each chromosome consists of two sister chromatids, connected by a structure called the centromere. The nuclear envelope starts to break down, and the mitotic spindle, composed of microtubule les, begins to form.<\/p>\n
\nDraw a labelled diagram of a Nerve cell and explain the structure.
\nAnswer:
\nA nerve cell, or neuron, is the fundamental unit of the nervous system. It is responsible for transmitting electrical signals (nerve impulses) between different parts of the body. Below is a labelled diagram of a typical neuron, followed by an explanation of its key structures.<\/p>\n\n
