This process is called Cloning. Cloning is the process of producing genetically identical copy of an organism or a cell, which may occur naturally or created in the lab. Naturally it may occur through processes such as asexual reproduction in organisms such as bacteria; where offsprings that are genetically identical to the parent are created.

Alborosie

Answer:

B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present

Explanation:

Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.

Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.

Whispered pectoriloquy is used to detect vocal resonance. It is  used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.

riadik2000 [5.3K]

Answer:

Glucose (sugar)

Explanation:  

We know that plants take in carbon dioxide and returns it in a form of oxygen. For the plant to be able to make oxygen they need to get power. The power is the sun rays and that is mixed with the CO2, making glucose. Anything that uses photosynthesis is a producer, so it makes its own food.
