Answer:Transcriptional Regulation
Explanation:
Eukaryotic gene expression can be regulated during the time of transcription and RNA processing, which takes place in the nucleus of the cell and then during the time of protein translation in the cytoplasm.
Further regulation is being carried during the time of post transnational modification. The conservation of energy is very important because it saves the overall energy and space in the body.
Hence, the most important point for the regulation would be transcriptional regulation.
Answer:
The correct answer is- e. I and II only
Explanation:
According to the biological species concept, a species is the population of organism in which the individual are able to interbreed with each other and also able to produce viable and fertile offspring.
Therefore here to determine whether polar bears and grizzlies are different species we have to get information that whether the F1 generation of grizzlies and polar bears is viable and able to produce their own offspring that means are F1 generation fertile. So the correct answer is e. I and II only.
Answer: Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability.
Explanation:
Shortened: This means the membrane only allows some things to pass through while others can't.
Hope this helps! ^^
