Of the six kingdoms now recognized, a two are eukaryotes, and four are prokaryotes. b four are plants, and two are animals. c two are prokaryotes, and four are eukaryotes. d four are bacteria, and two are eukarya.

The answer to your question is: letter C. two are prokaryotes and four eukaryotes

Explanation:

A two are eukaryotes, and four are prokaryotes. This answer is wrong because animalia, plantae, fungi and protista are eukaryotes.

B four are plants, and two are animals. This answer is wrong because only one kingdom is plants (plantae).

C two are prokaryotes, and four are eukaryotes. This answer is right there are two prokaryotes (eubacteria and archaebacteria) and the others are eukaryotes.

D four are bacteria, and two are eukarya. This answer is wrong there are only 2 bacteria not 4.

this would be a math

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
