The answer is; A
The operator site is usually associated with the promoter region of the operon. This region is bound by a repressor. The repressor acts as a physical barrier so the RNA polymerase does not bind to its promoter, or even if it binds, does not proceed to transcribe the genes.
Yes, all birds have feathers. About 9,700 kinds of birds live on earth. All birds have feathers and wings but not all birds can fly. Birds have as many as 25,000 feathers and they shed their feathers at least once a year.
Answer:
The answer is letter D, The storms cause wind and waves that move the sand from one place to another.
Explanation:
Along the coastline of Florida are their <em>beaches and barrier islands. </em><u>These islands are very important for the survival of plants and animals. </u>However, whenever a hurricane or a storm hits the area, it causes a dramatic change in the shape of the place. This is, primarily, because the storm causes the forces of wind and waves to move the sand from one place to another.
The movement of these can be towards or away from the mainland. <em>The fast movement</em> <u>causes the sand in the area to be deposited away from the shore,</u> thus creating sandbars. <em>The slow movement</em> <u>causes the sand from the sandbars to return back to the shore.</u>
Answer:
If their offspring can reproduce
Too bad there's not the options, but the answer must be the hydroxyl and carbonyl group.
The solubility of sucrose in water as well as organic solvents is very high. In non-aqueous solvents is generally lower. On the other hand, sucrose is not soluble in nonpolar solvents. This solubility in the polar solvent as well as the water is due to the hydroxyl (-OH) and carbonyl (-C = O) functions creating hydrogen bonds with the solvent molecules making it easier to dissolve.
