What is the total magnification of a microscope with two lenses when one lens has a magnification of 15, and the other lens has a magnification of 30? a. 15 b. 30 c. 45 d. 450

The right option is; d. 450

Magnification is the measure of the ability of any optical instruments such as a lens to enlarge (magnify) an object in an image.  To calculate the total magnification of an image that is viewed through the microscope, the power of the objective is multiplied by the power of the eyepiece.

As given in the question, the magnification of the two lenses are 15 and 30.  

Magnification = 30 X 15 = 450

Therefore, the total magnification of the microscope is 450.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
