The correct option is C.
Secondary consumers are those consumers who feed on primary consumers. Ladybug feed on soft bodied insects such as aphids. Aphids are pest and they feed on the crops which farmers planted, ladybug in turn feed on these aphids.
The correct choice is D.
A karyotype is the layout of chromosomes, in size order from largest to smallest. These chromosomes are ALWAYS in pairs, meaning that it would be easy to notice which of the 23 chromosome pairs have 3 chromosomes instead of the usual pair.
Answer:
d) genetic characteristics such as ribosomal RNA sequences
Explanation:
Carl Woese and his collaborators identified two major branches of prokaryotic evolution which are bacteria and archaea. They used 16S rRNA sequencing to study the similarities and differences between archaea and bacteria.
After sequencing the complete genome structure of Methanococcus jannaschii in 1966 which is an archaea they concluded that bacteria are more closely related than humans than bacteria.
After many years Carl Woese gave the three-domain system which divides prokaryotes into archaea and bacteria according to differences in their rRNA sequencing. Eukarya was the third domain. So the correct answer is d.
