Problem: In addition to tributary relations with the Kushans, the Han Empire received gifts from the Parthian Empire, from a king in modern Burma, from a ruler in Japan, and initiated an unsuccessful mission to Daqin (Rome) in AD 97 with Gan Ying as emissary. A Roman embassy of Emperor Marcus Aurelius (r. 161–180 AD) is recorded in the Hou Hanshu to have reached the court of Emperor Huan of Han (r. AD 146–168) in AD 166, yet Rafe de Crespigny asserts that this was most likely a group of Roman merchants. Other travelers to Eastern-Han China included Buddhist monks who translated works into Chinese, such as An Shigao of Parthia, and Lokaksema from Kushan-era Gandhara, India.
Who reached the court of Emperor Huan in AD 166?

Answer: A Roman embassy


Problem: Usually a Presbyterian church will not have statues of saints, nor the ornate altar more typical of a Roman Catholic church. Instead, one will find a "communion table," usually on the same level as the congregation. There may be a rail between the communion table and the "Chancel" behind it, which may contain a more decorative altar-type table, choir loft, or choir stalls, lectern and clergy area. The altar is called the communion table and the altar area is called the Chancel by Presbyterians. In a Presbyterian (Reformed Church) there may be an altar cross, either on the communion table or on a table in the chancel. By using the "empty" cross, or cross of the resurrection, Presbyterians emphasize the resurrection and that Christ is not continually dying, but died once and is alive for all eternity. Some Presbyterian church buildings are often decorated with a cross that has a circle around the center, or Celtic cross. This not only emphasized the resurrection, but also acknowledges historical aspects of Presbyterianism. A baptismal font will be located either at the entrance or near the chancel area. Presbyterian architecture generally makes significant use of symbolism. You may also find decorative and ornate stained glass windows depicting scenes from the bible. Some Presbyterian churches will also have ornate statues of Christ or Graven Scenes from the Last Supper located behind the Chancel. St. Giles Cathedral ( Church Of Scotland- The Mother Church of Presbyterians) does have a Crucifix next to one of the Pulpits that hangs alongside. The image of Christ is more of faint image and more modern design.
What did the Celtic Cross represent?

Answer: the resurrection


Problem: Many important biochemical reactions, such as energy generation, use concentration gradients across membranes. The general lack of internal membranes in bacteria means reactions such as electron transport occur across the cell membrane between the cytoplasm and the periplasmic space. However, in many photosynthetic bacteria the plasma membrane is highly folded and fills most of the cell with layers of light-gathering membrane. These light-gathering complexes may even form lipid-enclosed structures called chlorosomes in green sulfur bacteria. Other proteins import nutrients across the cell membrane, or expel undesired molecules from the cytoplasm.
How does electron transit occur in bacteria?

Answer:
between the cytoplasm and the periplasmic space
