Why do you think the snapper population changed the way it did?
maksim [4K]

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.

Two planets with the same mass and atmospheric conditions orbit a single star. Planet A is closer to the star than Planet B. Whi
sveticcg [70]

Answer:

Planet B is expected to be cooler than Planet A.

Explanation:

In the given case, planet A is closer to the star than planet B. Their atmospheric conditions and mass is same so their surface temperature will depend on their distance from the star. Since planet A is closer, it will receive more radiation from the star. In turn it will be hotter to re-radiate that energy back to space. Hence, average surface temperature of planet B will be lower than planet A.
