Answer:
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.

Explanation:
Answer:
a. They must be present in a large geographic area.
Explanation:
Index fossils can be used to determine the age of a rock strata with great precision, but they must be scattered over a large geographic area to be able to be used reliable for this type of measurement. Index fossils typically indicate a certain type of paleoenvironment belonging to a very specific prehistoric period and their formation coincides with the age of the rock layer.
A region based on common properties such as population is called

The plane would reach a latitude of 38°N.
When it comes to lines of latitude, the Equator is 0°. Locations south of the equator increase from 0° as you go further South and those north increase from 0° as you go North.
If you therefore go from 17°S northward, the degrees of latitude will keep decreasing till you get to 0° and then start increasing as you go North.
The new location in this case will therefore be North:
= 55 - 17
= 38 °N
In conclusion, the plane will keep going North until it passes the Equator at 0° then it will keep going North till it gets to 38°N.
