Answer:
D) Enzymes make nonspontaneous reactions become spontaneous
Explanation:
Being spontaneous or non-spontaneous in nature depends on the difference in energy levels between substrates and products of the reactions. A reaction with substrates at higher energy levels than the products are spontaneous ones. On the other hand, the reactions wherein products have higher energy content than the substrates are non-spontaneous.
Enzymes do not change the energy levels of substrates and products, so, they can not make a non-spontaneous reaction to become a spontaneous one. Enzymes only lower down the activation energy for a reaction and thereby make the non-spontaneous reaction to occur at a faster rate.

Answer:
O by building structures on natural habitat areas
Explanation:
The diversity within an ecosystem can be compromised by building structures on natural habitat areas.
An ecosystem is part of the environment made up of living and non-living components in their natural habitats.
- Diversity entails variations in the life forms within a particular ecosystem.
- When human-induced pressure begins to impact the environment, diversity is threatened
- Nature has its balancing effect the allow for a wide range of organisms to thrive.
- When human builds structures, part of the natural habitat is lost.
Although earthquakes often occur before a volcanic eruption, they are not the cause. The earthquakes are the result of magma (molten rock) moving underground leading up to an eruption. A few volcanic eruptions are thought to have been triggered or initiated by earthquakes, but this is not the typical case.
