The correct answer to this question is 3. Chromosomes are DNA molecules, which house an organism's genetic materials. These materials including packaging and chaperone proteins. The definitive discovery of chromosomes came in the mid 1880s from scientist Theodor Boveri. Chromosomes can be viewed under a light microscope, but they can only be viewed when the cell is going trhough the metaphase of cell divison. The recombination of chromosomes during meiosis and sexual reproduction have a vital role in the diversity of genetics. Humans have a total of 46 chromosomes, for each cell containts 23 pairs. Autosomes are twenty-two of the pairs, while the twenty-third pair is called a sex chromosome.

Should include:calcium released by the cisternae of the sr binds to troponin causing a confirmational change in the troponinthe aforementioned change causes the troponin/tropomyosin to move, exposing the myosin binding site to be exposed on the actinatp from the sarcoplasm binds to the myosin head, causing myosin to release actinatpase on the myosin head hydrolysis atp into adp and pi, which causes myosin to assume the cocked positionmyosin, containing adp and pi can cross-link with actinnow the energy from the hydolyzed phosphate bond is converted into mechanical energy and myosin pulls actin towards the center of the sarcomere, which causes the release of adp and pinow atp can bind, causing disruption of the cross-linking, which allows this process to repeat as long as atp and ca++ are presentin the absence of ca++, the myosin will remain in the cocked position, until ca++ raisestermination of the signal occurs when:action potential stops and ca++ within the motor neuron is pumped back out of the cell by active trasportaction potential stops and causes intracellular ca++ to be pumped back into the sr via active x-portach vesicles no longer undergo exocytosisachase breaks down achintracellular ca++ to be pumped back into the sr via active x-port

XerxesAccording to the inscription known as A1Pb, construction of the Hall of Hundred Columns at Persepolis (map 8) was started by the Achaemenid king Xerxes; the building was finished by his son and successor Artaxerxes I Makrocheir (465-424). This throne hall was Persepolis second largest building, measuring 70 x 70 meters. At an unknown moment, its function was changed and it became a store room, probably because the Treasuryhad become too small to contain all treasures that were hoarded in Persepolis. A new function may have been envisioned, however, because Artaxerxes III Ochus was building a new road and a new gate to the palace, suggesting that the Hall of Hundred Columns might have been used for audience. The entrance was to the north, where a portico was decorated by two large bulls. The entrances themselves - two on each of the four sides of the square building - were decorated with the usual motifs:. audience scenes, throne scenes, and royal warriors fighting against wild animals.

Thothmes I The Great Hypostyle Hall of Karnak, located within the Karnak temple complex, in the Precinct of Amon-Re, is one of the most visited monuments of Ancient Egypt. The design was initially instituted by Hatshepsut, at the North-west chapel to Amun in the upper terrace of Deir el-Bahri The hall covers an area of 50,000 sq ft (5,000 m2). The roof, now fallen, was supported by 134 columns in 16 rows; the 2 middle rows are higher than the others (being 33 feet (10 m) in circumference and 80 feet (24 m) high). The hall was not begun by Horemheb, or Amenhotep III as earlier scholars had thought but was built entirely by Seti I who inscribed the northern wing of the hall with inscriptions.[citation needed] Decoration of the southern wing was completed by Ramesses II. A series of later pharaohs added inscriptions to the walls and the columns in places their predecessors had left blank, including Ramesses III, Ramesses IV and Ramesses VI. The north side of the hall is decorated in raised relief, and was mainly Seti Is work. The southern side of the hall was completed by Ramesses II, in sunk relief although he used raised relief at the very beginning of his reign before changing to the sunk relief style and re-editing his own raised reliefs there. Ramesses II also usurped decoration of his father along the main north-south and east-west processional ways of the hall, giving the casual observer the idea that he was responsible for the building. Most of Seti Is reliefs in the northern part of the hall were respected however. The outer walls depict scenes of battle, Seti I on the north and Ramesses II on the south. Although these reliefs had religious and ideological functions, they are important records of the wars of these kings. On another wall adjoining the south wall of the Hall is a record of Ramesses IIs peace treaty with the Hittites that he signed in Year 21 of his reign.
