(problem 8) how do transcriptional activator proteins and repressors affect the level of transcription of eukaryotic genes?
masha68 [24]
Transcriptional activator proteins may control the level of transcription of eukaryotic genes by bind to promoters that enhance or regulate the transcription.
Repressors may control the level of transcription of eukaryotic genes by binding to DNA sequences that work either as silencers or promoters in order to inhibit the transcription impeding the access to where the transcriptional activator proteins may bind.

Nephron is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.

Plz help cause I don’t think this isn’t right at all
melamori03 [73]

Answer:

From left to right side

Explanation:

Diffusion is the process in which molecules move from a place of higher concentration to a place of lower concentration until a point comes when the concentration of the molecules is balanced in the both areas.

Now, if we look at the diagram, we see that molecules are highly concentrated on the left side, and next to that side is a semi permeable membrane through which they are getting diffused into the right side of the cell.

So, looking at it, it is very clear that molecules will move from left side (the most concentrated side) to te right side (the less concentrated side).


Hope it help!
