Answer:
The correct option is C and D.
Explanation:
There are certain plants which require certain temperature ranges to grow such as the Joshua trees. As these plants are not able to grow in warm conditions, hence it is better that these trees be grown in the north where the climate is cooler and best suitable for these Joshua trees. Hence, the correct option is C.
Also, if we want the trees to grow, we can limit their growth to only winters.
<span><span>A. </span><span>Fats would be the correct answer. For an organism to have energy, fats are burned when the cell diet does not consist of the fat needed from the food intake. Fats are necessary in order to transport other nutrients. Some vitamins are even fat soluble which means they need fats in order to be transported. Such vitamins are A, D, E, and K. Fats also provide protection for the vital organs from pressure and change in temperature by providing proper insulation and cushion. It also helps regulate body temperature.</span></span>
Answer:
Although it is controversial topic, it is not a recommended practice among socienty to cultivate BT corn when alternative methods of increasing plant yield are already available. On the other hand, scientists are encouraging more research on genetically modified (GM) solutions with lesser/reduced impact on ecosystem.
Explanation:
Although, cultivating BT corn helps improving the yield, reduce insecticides usage, and enhance the grain quality, it has been extensively debated to reduce this practice globally. This is because of severals reasons. At first, cultivation of BT corn affects non-target organisms that interact with the plant for symbiotic or neutral reasons including pollination. Due to genetic modificaitons, BT corn produce BT-proteins that kills the non-target organism. Secondly, it increases the insect resistance and those insects which survives even after chewing plant tissues of BT-corn, they are found to have resistance against several toxins at high doses. Once these chemicals enters the food chain, they could be extremely toxic to other naturally growing organisms.
Prince Charles stated that use of GM plants is disaster and should be banned immediately. Likewise, he said that it is also impacting the climate change. On the other hand, Prof. Smith showed a contradictory opinion and said that the views of Prince Charles are saddening. He is seeing the one sided picture only. He should ask for extensive research rather discouraging this aspect of modern science.
In my opinion, I would also say that the technology should be improved and make more eco-friendly rather than complete abolishing especially when the apparent benefits are greater than the harmful effects.
