Ksenya-84 [330]

Answer:

B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.

Explanation:

According to natural selection theory, organisms need to continuously adapt and evolve within an environment or risk being wiped away from that environment.

Organisms that are not able to adapt to an environment are gradually replaced by those that have the capability to adapt and survive in that environment.

Those that are able to survive go ahead to reproduce and give rise to offspring with inherent ability to survive while those that cannot survive die off.

The correct option is B.

What process occurs in prokaryotes but not in eukaryotes?
Naddika [18.5K]

Explanation:

In the given question, the options are not provided in the question and neither they are found anywhere therefore based on the previous knowledge this can be answered.

Since both the prokaryotes and eukaryotes are living therefore they perform the metabolism or chemical reactions in the form of process.

Both eukaryotes and prokaryotes perform almost similar process like the cellular respiration, photosynthesis by green colored organisms, the Central dogma related process like the replication, transcription and translation.

The central dogma related processes differ in these process only in terms of the site they are performed and a few modifications which are characteristics of the eukaryotic cells.

In prokaryotes, the transcription and translation are coupled and takes place in the cytosol whereas in eukaryotes transcription in the nucleus and translation in the cytosol.

Also in eukaryotes, modifications like the splicing, alternative splicing, capping and tailing are observed which are not observed in the prokaryotes.
