Answer:
Well, on one hand, this is a good thing as negative effects of the high demand for wood such as deforestation can be minimised. This will also sustain the supply of wood for several applications. However, there could be negative consequences of propagating such genetically-modified trees, which were not stated or are not yet known. For instance, the trees could be extreme soil nutrient consumers—depleting soil nutrients at a faster rate than they can be replenished and rendering such soil infertile in a short period.
Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.
Geologists use these events that are often wide spread to delineate geological periods.
