The answer is phrenic nerve. Originates in the neck (C3-C5) and passes down between the lung and heart to reach the diaphragm. There are two phrenic nerves, a left, and a right one hence called a bilateral nerve. It also contains motor, sensory, and sympathetic nerve fibers hence called a mixed nerve. It is the only source of motor innervation to the diaphragm, hence critical for breathing.
Answer:
The correct option is B. Nucleus
Explanation:
The structure in the diagram is a nucleus because the nucleus is a membrane-bound organelle mostly round in shape and it is present inside the cells.
The structure in the diagram cannot be cytoplasm as cytoplasm is a fluid in which organelles float.
The structure in the diagram cannot be a cell wall as a cell wall is the outer layer of a cell and it is not present inside of the cell.
The structure cannot be a flagellum as flagellum are hair-like structures. Hence, option A, C and D are false.
According to this nifty chart, CCC codes for the same amino acid as CCA (proline).
Since CCC and CCA are both codons for the amino acid proline, there will be no difference in the structure of insulin. Moreover, there will be no change in function, and the person will not be diabetic C:

Answer:
Answered below
Explanation:
Carbohydrates are biomolecules that contain hydrogen, carbon and oxygen. They are generally structured as a chain of carbons with hydroxyl groups, and ketones or aldehydes. The subtypes include;
Monosaccharides
Disaccharides
Polysaccharides
Monosaccharides are generally represented by the formula CH2On. They are classified based on the number of carbon atoms they have. Example, hexoses have 6 carbon atoms, pentose, 5, diose, 2 etc. They are also classified based on whether they have ketones or aldehydes. Examples of monosaccharides are glucose and fructose.
Disaccharides are formed when two monosaccharides form glycosidic bond through a dehydration reaction. Examples of disaccharides include; maltose, lactose, and sucrose which is made up of glucose and fructose. An oligosaccharide is made up of 2-10 monosaccharides and are often components of glycoproteins or glycolipids.
Polysaccharides, also called complex carbohydrates are long-chain carbohydrates made of repeated monosaccharides linked by glycosidic bonds. Examples are starches and glycogen.
