B. because they are not manufactured by the body
The mass is made up of protons and neutrons, the valence electrons only determine stability, not mass
Answer:
This happens because pollination processes are increased over time, with time prevailing in the environment and in the air, and people with time hypersensitivity are more widespread over time.
Explanation:
Many scientists investigate these situations and mainly affect people at the respiratory level since pollen is inhaled, generating possible edema and bronchoconstrictions.
Other researchers also relate it to environmental pollution since it increases or extends the heat periods throughout the year, so this event is aggravated in patients with asthma and allergies, since the pollution has a direct effect on the airways.
Many particles suspended in the air by pollination and contamination are the cause of inflammation and bronchial hyperreactivity in patients with chronic pathologies. Substances like nitrogen oxides, sulfur dioxide, carbon monoxide and ozone promote the production of symptoms and exacerbations in children with asthma.
