Comparative morphology
compares the embryo development of organisms of different species
compares the anatomy of organisms of different species
organizes fossils into a timeline of organism evolution
analyses the similarities and differences between organisms of the same species

The correct answer is -

compares the anatomy of organisms of different species.

Explanation:

Comparative morphology can be described as the study of various structural patterns within the body of organisms belonging to different species. It also compares the anatomy of organisms of different species so as to find out the differences as well as similarities between different organisms.

In this way, it considered as the basis for taxonomical categorization of organisms.

Thus, option second is the right answer.

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

the backbone of the dna and rna compound is sugar phosphate.
