Answer:
The correct classification is:
Non-essential Elements:
- Helium
- Argon
- Aluminum
Essential Bulk Elements:
- Hydrogen
- Carbon
- Nitrogen
- Calcium
Essential Trace Elements:
- Iron
- Copper
Explanation:
Essential Elements:
Essential elements are elements that are strictly required in human diet as they are crucial for normal bodily functions and the deficiency of which can result in diseases or abnormalities. Out of the total 115 elements, 19 are considered essential for the human body. These include:
- Essential Bulk Elements:
Essential elements that form the bulk of our body and form the fundamental organic compounds required in the body. These are required in kilograms (kgs) in the diet. These include:
- Oxygen
- Carbon
- Nitrogen
- Sulfur
- Hydrogen
2. Essential Trace Elements:
Essential trace elements are required in relatively lower quantities in the body but their deficiency results in disease and abnormal body function. These are required in milligrams (mg) in the diet as excessive consumption or accumulation can also lead to abnormalities. These include:
- Iron
- Silicon
- Zinc
- Molybdenum
- Copper
- Manganese
Answer:
Affinity to water
Explanation:
Amino acids can be divided into two groups: non-polar and polar. The polar group consists of asp, glu, arg, lys, his, ser, thr and tyr. They can make hydrogen bonds and interact with water because they have an OH or NH2 group. <em>This polarity affects the tertiary and quaternary structure of proteins because a polar molecule will tend to be on the outside because of its hydrophilic properties.</em>
