Answer:
<u>Uranium</u> is the inner transition metals is critical to the nuclear power industry.
Explanation:
Uranium is a common transition metal found in rocks and is used for nuclear fission reactions. In a nuclear fission reaction, a neutron atom is hit on a uranium atom. As a result, the uranium atoms breaks down releasing huge amounts of energy. Also, more neutrons are released by the breakdown and hence the this neutron hits other uranium atoms and the cycle continues. The most active radioisotope of uranium being used in nuclear fission reactions is U-235.

They are both ald.open.toses.
Explanation:
Transport of a substance from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the extracellular fluid is called <u>transcellular transport</u>.
The two routes of transport of substances across the epithelium of the gut are by transcellular method and paracellular method.
Transcellular transport refers to the transport of solutes across a epithelial cell layer through the cells. The best example is the movement of glucose from the intestinal lumen to the extracellular fluid by the epithelial cells. The epithelial cells use the active transport to generate the transcellular transport. Active transport refers to the transport of substances from a region of its lower concentration to a region of its higher concentration against the concentration gradient using cellular energy.

Edit
The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.
