Answer:
The following are the steps for making the human insulin protein for the health care market:
1. Obtain the DNA from a human being who does not have diabetes.
2. Modify the human gene, and provide it a promoter, which will get turn on when placed within the E.coli cell.
3. Separate and make copies of the gene encrypting the insulin protein.
4. Application of electroporation or heat shock method in order to administer the human insulin gene within the living E.coli cell.
5. Development and growth of E.coli in the fermentation culture, and then extract and sell the humulin in the market.
If there is less water in the bottle, then the note played is lower because there is more air to move around.
Using two different media (air and water) in glass bottles show how the speed of vibrations affects pitch.
Pitch is the way that your ear and brain order sounds based on their frequency (vibrations per second).
Rapid vibrations (high frequency) that reach your ear are categorized as a "higher" pitch, while slower vibrations (low frequency) are categorized as a "lower" pitch.
When you tap a glass of water with a pencil or spoon the water molecules vibrate and create sound waves through the water. More water means slower vibrations and a deeper tone.
The bottle with the most water will have the lowest pitch while the bottle with the least water will have the highest.
When Wanda and Marita blow across the top of the bottle, they set the air molecules vibrating and produce sound waves. In this case, more water results in a higher pitch, as opposed to tinkling the bottle. When the bottle has a small amount of water in it, the air molecules have lots of room and vibrate slower. Adding more water gives them less space to vibrate in, making them vibrate faster and producing a higher pitch.

Earth is a beautiful planet that revolves around a star called Sun, which is located in one of the arms of our Milky Way Galaxy. It is the only planet known to support life in the Solar System. Humans are the most intelligent civilization on this planet. It's blue when seen from space. Recently, Earth 29 spacecraft was able to land on this planet, after 28 unsuccessful landings of Earth series of spacecrafts. We were able to learn many things about humans, most important of these was the most spoken language of them, which they call English. According to experts, humans are not yet ready to know about our existence. It can take about 1 or 2 more centuries, until they are ready to know about us.
The answer is A or the first one
