Answer:
Probability that at least one of them will be affected = 3/16 + 3/16 + 1/16 = 7/16
Explanation:
If both parents are heterozygous for a genetic disease; Xx and Xx
The offspring's they will produce will be as follows ; XX, Xx, xX, xx
- Probability that first child will be affected = 1/4
- Probability that first child will not be affected = 1 - 1/4 = 3/4
- Probability that first child have it and second does not = 1/4 x 3/4 = 3/16
- Probability that first child does not have it, second child have it = 3/4 x 1/4 = 3/16
- Probability that both of them will have it = 1/4 x 1/4 = 1/16
- Hence, Probability that at least one of them will be affected = 3/16 + 3/16 + 1/16 = 7/16

I might have messed up but i believe this is correct.
Explanation:
Answer:
C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.
Explanation:
When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.
