Prokaryotic cells lack a nucleus. Therefore, the genes in prokaryotic cells are:

a) All expressed, all of the time

b) Transcribed and translated almost simultaneously

c) Transcriptionally controlled because translation begins before transcription ends

d) B and C are both true

d) B and C are both true            

Explanation:

Prokaryotic cells: The term "prokaryotic cells" are described as cells that don't consist of "membrane-bound organelles" or "true nucleus". However, the organisms that come under the domain of Archaea and bacteria tend to possess prokaryotic cells and it has been described that organisms that consist of prokaryotic cells are abundant in nature and make most of the Earth Biomass. Prokaryotic cells don't possess the nucleus rather have one chromosome.

In the question above, the correct answer is option D.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
