Helper T cells are found in the <u>Thymus.</u>
Explanation:
Immature T-cells are formed in the bone marrow, just like any other blood cells, through the process of hematopoiesis. These immature T cells are then transported to the thymus where they mature and differentiate into the different types of T cells; cytotoxic, helper and regulatory. T-helper cells, also called CD4⁺ cells, are important in activating B-cells and T-cytotoxic cells in case of infection.

Answer: Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.
Explanation:
Answer:
1. Cytokinesis
2. G1 phase
3. Karyokinesis
4. Metaphase
5. Prophase
6. Telophase
7. Anaphase
8. Prophase
9. Telophase
10. Metaphase
11. Synthesis phase
Explanation:
1. Cytokinesis- Cytokinesis refers to the phase of the cell division during which the cytoplasm of the cell divides.
2. G1 phase- G1 phase is the longest phase of the cell cycle during which the cell performs the normal function and the cell remain in this phase for 11 hours.
3. Karyokinesis- The phase during which the nuclear division takes place or the nucleus divides.
4. Metaphase- the phase during which the chromosomes are aligned at the centre or the equator of the cell.
5. Prophase-prophase is the phase of the cell during which the chromatin gets condensed to form chromosomes.
6. Telophase- is the phase during which the mitotic spindles break and the nuclear envelope reappears.
7. Anaphase- Anaphase is the phase during which the chromosomes move to the opposite poles.
8. Prophase-During prophase the nuclear membrane disappears and the chromatin condenses to form the chromosomes.
9. Telophase- the phase during which the chromosomes are decondensed to form the chromatin.
10. Metaphase- the phase during which the mitotic spindles are formed which will attach to the centromere of the chromosomes.
11. Synthesis phase-the phase during which the DNA replication begins and the amount of DNA is doubled.
