Answer:
c. binds to allolactose and becomes inactive, allowing lac gene expression to occur.
Explanation:
Interaction between allolactose and repressor leads to allosteric repulsion which makes repressor inactive leading to the lac gene expression. This is the reason why allolactose is known as the inducer of lac operon becasue it causes gene expression in lac operon.
In the absence of allolactose, the repressor binds the operator and does not allow RNA polymerase to do transcription.
Answer:Water. Earth. Fire. Air.
My grandmother used to tell me stories about the old days, a time of peace when the Avatar kept balance between the Water Tribes, Earth Kingdom, Fire Nation, and Air Nomads. But that all changed when the Fire Nation attacked. Only the Avatar mastered all four elements. Only he could stop the ruthless firebenders, but when the world needed him most, he vanished. A hundred years have passed and the Fire Nation is nearing victory in the War.
Two years ago, my father and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my brother to look after our tribe. Some people believe that the Avatar was never reborn into the Air Nomads, and that the cycle is broken. But I haven't lost hope. I still believe that somehow, the Avatar will return to save the world.

Water. Earth. Fire. Air.
Long ago, the four nations lived together in harmony. Then, everything changed when the Fire Nation attacked. Only the Avatar, master of all four elements, could stop them, but when the world needed him most, he vanished. A hundred years passed and my brother and I discovered the new Avatar, an airbender named Aang, and although his airbending skills are great, he has a lot to learn before he's ready to save anyone. But I believe Aang can save the world.
When it lacks an F plasmid it is called F-
D is the answer. The level of matter cannot be shifted, it can only stay constant even during chemical reactions.
A neuron is nerve cells that transfer information within the body, chemically over short distances, using electrical signals over long ones.
As it turns out, most resting neurons are permeable to Na+ and CL- as well as K+. K+ will try to drag the membrane potential toward its (positive) equilibrium potential, while NA+ try to drag the membrane potential to its negative equilibrium potential.
The real membrane potential will be between NA+ and K+ of equilibrium potential<span>. However, it will be closer to the equilibrium potential of the ion type with higher permeability.</span>
