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.
Answer:
The Answer is Letter E.
Explanation:
<em>The way membranes of a eukaryotic cell vary is certain proteins are unique to each membrane. </em>
The eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue.
What is a cell? Why is it called the basic unit of life?

Answer:
1.The eyes, a sensory organ, see the ball.
2.Sensory nerves transmit the information to the brain.
3.The brain processes the information.
4.The brain sends signals to the motor nerves.
5.Motor nerves carry the signal to the hand muscles.
Explanation:
When we receive a stimulus by any of our 5 senses (sight, touch, smell, hearing or taste) our body will react to this. Once that the stimulus is received ( in this case seeing the ball) a signal is send through the sensory nerves to the brain. In the brain the information will be processed and an answer will be given through the motor nerves in order to move the muscles and catch the ball. All this process is made in seconds.
<span>Macular degeneration is a condition in which individuals may have relatively normal peripheral vision but are unable to see clearly what is right in front of them.
Macular Degeneration is the leading cause of vision loss, affecting more than 10 million Americans “ more than cataracts and glaucoma combined.
At present, Macular Degeneration is considered an incurable eye disease.
Macular Degeneration is caused by the deterioration of the central portion of the retina, the inside back layer of the eye that records the images we see and sends them via the optic nerve from the eye to the brain. The retina's central portion, known as the macula, is responsible for focusing central vision in the eye, and it controls our ability to read, drive a car, recognize faces or colors, and see objects in fine detail.</span>
