Hypothalamus
The hypothalamus maintains a steady internal environment for the body.
The hypothalamus is a complex part of the brain that is located under the thalamus and above the pituitary gland. One of the main roles of the hypothalamus is to maintain homeostasis by keeping the human body in a balanced condition. The hypothalamus plays a part in various important functions of the body such as appetite and weight control, body temperature, emotions, sleep cycles, stress, blood pressure and levels of hormones in the circulation.
After crossing over of peonies, one with purple flowers and long stems, and the other with white flowers and short stems we will get the number of offspring 83 with purple flowers and short stems; 29 with purple flowers and long stems; 26 with white flowers and short stems; and 9 with white flowers and long stems.
A dominant allele is one that nullifies the effects of a recessive allele. The allele that is covered up by the dominant allele is known as a recessive allele.
This shows that a plant with purple flowers and long stems is carrying a dominant allele that masks the effect of the recessive allele in a plant with white flowers and short stems.

Answer:
1. meiosis 2. meiosis 3. meiosis 4. Binary fission 5. mitosis and meiosis 6. mitosis 7. meiosis 8. mitosis and meiosis 9. mitosis 10. Binary fission 11. meiosis.
Explanation:
The process of mitosis ad meiosis is a type of cell division that occurs in eukaryotes. The type of cell division in prokaryotes including bacteria is the binary division in that they do not have nucleus.
Mitosis is a type of division that produces identical diploid cells as the parent diploid cell. It involves only one division and involved in replacement of damaged tissue and for growth and development.
Meiosis is a type of cell division that produces unique daughter cells with genetic variation as a result of genetic recombination that occurs in the crossing over event in the interphase 1 of meiosis. This type of division involves two division (meiosis II and II) and also produces haploid cells. The parent cell is a germ line cell that was first diploid and then undergoes this form division producing haploid cells to be transferred to offspring.
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.
