The correct answer is D. Mine claim
Explanation
Mine reclamation is a technique for restoring areas that had been exploited previously by mining activity. This technique gives new use to the land once all minerals are extracted to revitalize the old mine that has left with some damage after it. In general, in these spaces are established recreation and leisure places for people like amusement parks. In other cases, Mine Reclamation promotes the creation of natural ecosystems for birds and other animals. Due to the above, it is correct to affirm that this technique was put into practice in the Six Flags park in San Antonio because the place where there was a mine, another place was established giving new use to this land. So the correct answer is the D. Mine reclamation.
Answer:
The weeds will become tolerant to the herbicide through repeated exposure.
Explanation:
Genetic engineering refers to the procedures that are used to change the genetic composition of an organism by supplementing the desired genes. The herbicide-resistant crops are developed in order to withstand specific broad-spectrum herbicides that destroy the surrounding weeds, however, leave the cultivated crop intact.
The cultivation of herbicide-resistant crops encourages and substantially enhances the application of herbicides, leading to overuse of herbicides, in order to maintain the production of crops. However, this overuse application of the herbicides will eventually result in the generation of weeds that become resistant to herbicides.
<span>The brain is a very complex organ in humans. Although we still have a lot to learn about it, decades of studies in both living and dead humans had revealed that the brain is crosswired, meaning the right side of the brain controls the left side of the body and viceversa. It’s also the part of the brain associated with arts and our creativity. Therefore the answer is B</span>
