The lac operon controls the transcription of a group of genes involved in metabolizing lactose in E. coli. A group of scientists

tested how to activate the lac operon. In four different mediums, they varied whether glucose or lactose was present in the medium, as indicated by a or -.The scientist discovered that the lac operon is inducible, repressed by glucose and induced by allolactose. Which medium has the right conditions to metabolize lactose

Answer:

The correct answer would be - medium with lactose present and glucose absent.

Explanation:

There are genes present in lac operon that takes part in the lactose metabolism. These genes expressed only if a medium has lactose in absence of glucose.

In the absence of glucose and lactose is present, due to inducer the lac repressor is removed from the operator. This leads to the binding of CAMP to DNA as the CAMP levels are high. It helps in high transcription levels b binding RNA polymerase to promotor.

The change of cell volume is principally due to the loss or gain of
Anna11 [10]

Answer:

Water

Explanation:

In simple words, the volume of a cell refers to <u>the amount of water it contains</u>.

In eukaryotic cells may change their volume according to the effects of either the loss or gain of water. Furthermore, these changes in cell volume are extremely important as they work as a signal for different cell processes such as migration, proliferation, or death.

Therefore, the change of cell volume is principally due to the loss or gain of <u>water</u>.

What is the difference between membrane distillation and pervaporation?
zysi [14]
<span> The pervaporation process is a relatively new, having common elements, reverse osmosis and gas permeation . The separating liquid mixtures by pervaporation difference in vapor pressure between the feed and the permeate. This difference in vapor pressure can be obtained in different ways: by vacuum applied to the permeate ,the most used laboratory procedure, or by cooling the permeate vapor, causing a partial vacuum, and most common industrially. The membrane destillation use heat streans to provide the evaporations. The pervaporation uses differente methods. I hope it help.</span>
