Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb
Offspring
4 AaBb - freckled and dimpled
4 Aabb - freckled and non dimpled
4 aaBb - non freckled and dimpled
4 aabb - non freckled and non dimpled
1. <em>Probability that the parents will have a dimpled child</em> = 8/16 or 1/2
2. <em>Probability that they will have a child with freckles</em> = 8/16 or 1/2
3. <em>Probability that they will have a child with freckles and dimples</em> = 4/16 or 1/4

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
