Answer:

D the hypothesis was just a guess and does not have to be supported by data

Explanation:

The idea of experimentation is to see what happens in practice.

You could predict what could happen and that's where the hypothesis came from.

If the experiment in practice has the same results as the hypothesis, good you can move forward.

If it's not, it was worth it to know your hypothesis was wrong and need to research to get things better and create a new type of experiment to get data.

Determine why people who live in warm areas have a longer periods of allergic reactions to pollen then people who live in colder
astra-53 [7]

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.
