Abiologist examines a single-celled organism isolated from a hot spring. the organism is a photosynthetic halophile that uses the pigment bacteriorhodopsin. in which kingdom should the biologist classify the organism? a.  bacteriab.  protistac.  fungid.  archaea

The right answer is D. Archaea.

Bacteriorhodopsin is a transmembrane protein, formed of seven helices, inserted into the walls of certain bacteria such as Halobacterium salinarum. Bacteriorhodopsin has a chromophore, retinal, which allows it to convert light energy into chemical energy (photosynthesis).

It serves as a model for proton pumps controlled by light. It is well studied for its bioenergetic properties and as a possible data storage medium.

By the way, Halobacterium salinarum is a species of aerobic halophilic archaea (not part of the kingdom of bacteria but archaea) found in environments with high salt content such as salted fish and various foods rich in salt , the salt marshes or the salt lakes

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
