Geostationary satellites are located exactly above the Earth’s equator and revolves around the Earth in a circular orbit. Their revolving speed and direction (West to East) are exactly same as that of the Earth, which makes it look stationary from the Earth’s surface.

Bacteria are prokaryotes. They are single-celled organisms and microscopic. It does not have well defined nucleus and cell organelles. Thus, mitochondria is absent in them.

Bile juice is produced by the liver and stored in the gallbladder, which is a small organ located beneath the liver. When needed, bile is released from the gallbladder into the small intestine to aid in the digestion and absorption of fats and fat-soluble vitamins. So, the correct answer is the liver secretes bile juice, and it is stored in the gallbladder before being released into the small intestine.

A geostationary orbit, geostationary Earth orbit or Geosynchronous Equatorial Orbit (GEO), is a circular orbit 35786 km (22236 mile) above the Earth’s equator and following the direction of the Earth’s rotation. An object in such an orbit has an orbital period equal to the Earth’s rotational period (one sidereal day).
