Tropospheric ozone is harmful, damaging plants and human health while ozone at the stratophere level screens out mutagenic ultraviolet radiation.

Explanation:

Ozone is dangerous and harmful in the lowest layer of the Earth's atmosphere. This layer is called troposphere. The reason why it causes damage to plants and human health it is because ozone is a reactive gas that affects plant synthesis and causes smog (a form of air pollution that is particularly dangerous to sensitive respiratory diseases such as asthma). However, ozone is helpful in the second layer of the Earth's atmosphere: the stratosphere.  It prevents and blocks dangerous ultraviolet radiation.

there's multiple reasons why the conquistadors were so successful in colonizing central america, and some of them are:

- they were seen as gods;

at the beginning, the spanish settlers were seen by the natives as gods, and this was mainly due to their white skin, and the way they came with their boats.

- possessed superior weaponry;

the spanish had gunpowder and guns, as well as cannons, while the natives did not had any fire weapons.

- made cleaver alliances;

they used the situation of tribes hating each other, so they made alliances with some of them which served them very well.

- brought diseases;

the native people were not immune to certain diseases the europeans brought with them, so they were dying from seeming harmless things for european standards.
