Answer:
Anaphase II.
Explanation:
Cell division may be defied as the phenomena by which the cell multiply and increases its number under the influence of cell cycle checkpoints. Two main type of cell division are meiosis and mitosis.
The meiosis result in the formation of four haploid cells from the single parent diploid cell. The Anaphase II of meiosis leads to the disjoin of the sister chromatids and the separation of chromatids. This is similar to the anaphase of mitosis.
Thus, the correct answer is anaphase II.
<span>When a bone breaks your body immediately begins working to heal it. Within the first hours of a fracture a blood clot forms around the break and special cells call phagocytes begin cleaning germs from the bone fragments. Then, a soft callus composed of collagen is created around the break. Next, a hard callus forms as osteoblast cells work to create new bone to aid in the reconstruction process. After all is said and done the bone is remodeled by cells called osteoclasts. The bone will be completely rebuilt in 3-9 years.</span>

Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
Answer:
When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed.
