When glucose is high, camp is : cap bind the lac operator, and rna polymerase bind the lac promoter. high; does; does low; does not; does high; does not; does low; does not; does not none of the answers is correct?

When glucose is high, camp is low : cap doesn't bind the lac operator, and RNA polymerase doesn't bind the lac promoter.

Explanation:

The lac operon is a molecule responsible for the rapid transport of lactose in Escherichia coli, mainly, but it can be found in other bacteria. This molecule is essential to regulate several factors within the bacterial cell, however the main factor regulated by it is the availability of glucose and lactose in the environment. WWhen glucose is high, camp is low: cap doesn't bind the lac operator, and rna polymerase doesn't bind the lac promoter.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
