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.
Answer:
C)The luminal side of the thylakoid membrane has a higher pH than the stromal side.
Explanation:
During the photophosphorylation, the electrons move through many electron carriers which allow the transport of hydrogen ions in the luminal side against the concentration gradient. This allows the increase in the Hydrogen ion concentration to the luminal side of thylakoid membrane and reduction in the hydrogen ion concentration of the stromal side.
Therefore due to the increased concentration of H⁺ ions in lumen during the photophosphorylation, the lumen has a lower pH than the stroma. During photophosphorylation, the pH of lumen decreases up to 4 and the pH of stroma increases up to 8. So the false option is C.
Answer:
C. The moon's gravitational pull and Earth's rotation
Explanation:
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
