what happens to the expression of the laci gene if lactose is not available in the cell?
the laci gene increases its rate of transcription.
the laci gene turns on. the laci gene turns off.
there is no change—the laci gene is constitutively expressed.

There is no change, the lac l gene is constitutively expressed, regardless of the presence of lactose.

Explanation:

Lacl gene codes for the lac repressor hence is always expressed to produce lac repressors which may or may not be bounded dependent on the presence of lactose. Lacl gene expression is not regulated, thus is constitutively expressed.

the answer is :

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.
