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.

What’s the difference between CAM plants, C3 plants and C4 plants??
Degger [83]

Answer:

C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.

Vesna [10]
Being open to the opinion of others


The civic virtue of diversity dictates that one is able to accept that humans are diverse and there is a variety of people, thoughts and mindsets in the world. In order to practice this virtue, one must be open to the opinion of others, since everyone has the right to have an opinion. This does not necessarily mean agreeing with the opinion of others, just accepting that they are entitled to their own.
