Any moving object can exhibit kinetic energy, as kinetic energy is also known as Motional energy.

In the given options, only a space station orbiting Earth is in motion and all the other are in rest position.

Hence, option C) a space station orbiting Earth is only exhibiting kinetic energy.

Anaerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O2) are available. 

Hence, Anaerobic glycolysis occurs without oxygen.

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another.. This bond generates two oppositely charged ions.

In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Example ::

One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.

Joseph Priestley and Carl Wilhelm Scheele both independently discovered oxygen in the year 1774, but Priestly is usually given credit for the discovery.

An electric fuse is based on the heating effect of the current.
