Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.

Answer: by using artificial light (grow light) in place of sunlight
Explanation: Plants generally needs sunlight to grow and survive through a process known as photosynthesis, this is when Plants and other organism uses sunlight to convert water, carbon dioxide and minerals into energy rich compound (starch) while oxygen is been released into the environment.
However in the absence of sunlight, artificial light know as grow light can be used, these lights are design in such a way that it emits lights of wavelengths that are appropriate for photosynthesis. The grow light replaces the sun as a source of photons in the process of photosynthesis.
Proximal convoluted tubules (PCT)
Proximal
convoluted tubules (PCT) are first part of the renal tubule that extends from
the Bowman’s capsule to the descending arm of the thin loop of the Henle. PCT
is made up of cells that contain many mitochondria that produce ATP for the
energy –intensive resorptive processes.
