Answer:

The correct answer is option A, that is, they require more healthcare, immunization, and check-ups for children.

Explanation:

TFR or total fertility rate signifies towards the average of children possessed by women in a nation during their entire lifetime and is associated with other elements like fertility rates and growth of population. The high TFR signifies that there are more young people and children. Thus, with the population comprising more children, there would be a requirement for more healthcare like more immunization and check-ups, and also more spending on education is required.

(Ch. 27.4) Many people are allergic to substances in the environment, such as ragweed pollen, as well as foods, such as peanuts.

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.
