Answer:
The given blank can be filled with the steady state theory.
Explanation:
The theory based on the perfect cosmological principle is the steady-state theory. On the basis of this theory, the universe is isotropic, homogenous, and immutable. This hypothesis did not reject the expansion of the universe, however, it believed in the spontaneous generation of matter to counteract the observed expansion, that is, maintaining the average density same.
This theory was suggested by Bondi, Hoyle, and Gold in 1948. The steady-state theory lost its objectives when the discovery of the cosmic background radiation was done.

Answer:
Genus
Explanation:
In the scientific name "Panthera tigris", Panthera is the name of the genus and the "tigris" is the name of the species. Similarly in the name "Panthera leo", the name "Panthera" denotes the genus while "leo" is the species. This means that the tiger and lion belong to the same genus. They both belong to the genus "Panthera".
Though the species of the tiger is "tigris" and that of the lion is "leo". Both are the species of the same genus since the genus includes closely related species. The members of these different species can not interbreed but share some common features as they belong to the same genus.
