Why are some of carl linnaeus’s classifications of organisms incorrect?
linnaeus did not study the anatomy of organisms.
linnaeus’s work accounted for evolution.
linnaeus did not use structural comparisons.
linnaeus primarily used physical characteristics.

The right option is; Linnaeus primarily used physical characteristics

Some of Carl Linnaeus’s classifications of organisms are incorrect because he primarily used physical characteristics.

Carl Linnaeus, known as the father of taxonomy, was a Swedish biologist who classified organisms according to their physical characteristics. Carl Linnaeus proposed that there were three major groups, named kingdoms. These kingdoms were animals, plants, and minerals. He divided each of the kingdoms into five levels which are; class, order, genus, species, and variety. Organisms were arranged in these levels according to their traits, which include physical appearance such as body size, and shape, similarities of body structure, and way of obtaining food.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
