Explanation:
During metamorphism, pressure and temperature, a times fluids causes the mineral composition and texture of a parent rock to change.
Texture is the arrangement and orientation of mineral grains in a rock.
- Rocks that are made up of single mineral phase rarely undergo compositional changes.
- Rocks like quartz sandstone and limestone do not change minerals.
- In limestone, the mineral calcite is dominant. Since there are no other minerals to combine with, it's composition does not change.
- But a metamorposed limestone undergoes changes in texture.
- The searing heat and pressure causes the grains to recrystallized, they interlock to form a granular pattern.

<u>Answer:</u>
In ecology, catastrophes permanently alter the physical structure of the existing environment.
<u>Explanation:</u>
- The ecological disturbances include flood, strom, plague, fires, earthquakes, tsunami, volcanic eruptions, climatic change and impact of humans on the environment like deforestation ,nuclear testing etc.
- These factors can have a visible impact on the structure of the earth and permanently alter the environment.
- The visible effects of these disturbances are global warming, extinction of selective species, change in the course of rivers, submergence of coastal areas, sudden movement of the tectonic plates and formation of sudden cracks on the earth's crust.
Angiosperms do not have cones like gymnosperms, instead, they have flowers and the ovule is protected by the carpel which after fertilisation forms the seed. The similarity between angiosperms and gymnosperms is that both have leaves, stem and roots.
B. Ammonia. Ammonia has a pH level of about 11, and anything higher than 7 is more basic and anything less than 7 is more acidic. 7 is considered neutral.
