2. suppose each trial equals 1,000 years. what is the half-life of virtualium?

The Virtualium half-life is 12 years.

Explanation:

Half-life, also known as semi-disintegration period, is the time required for half the number of atoms of the radioactive isotope present in a sample to disintegrate.

Disintegration is not related to the extinction of the atom, that is, the atom does not cease to exist. In fact, what happens is the natural decay that the atom undergoes. In decay, the atom (X), when emitting alpha and beta radiation, automatically changes into a new chemical element (Y), which occurs incessantly until the atom is no longer radioactive (stable atom).

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
