The correct matches are:
1. Sea level (0 m) - 100%
2. Mid-level elevation (4,500 m) - 57%
3. Peak (8,850 m) - 33%
The level of oxygen in the atmosphere depends a lot on the elevation. The smaller the elevation, the higher the oxygen level, and vice versa, the higher the elevation, the lower the oxygen level. So we have a situation in which the oxygen level is the highest at 0 elevation, or rather at sea level. As we go to higher elevations, let say to around 4,500 m, the oxygen level is significantly dropped, which makes it difficult for breathing. If we go even on higher elevation, like 8,850 m, than the oxygen level will much lower, and a human will need to undergo intense long training and also carry oxygen with him/her in order to survive.
The correct answer is (b) Increase
Pines trees are infected by different insects during the adverse and stressed environmental condition. Pine borer beetle is pest that infect pine tree during the stressed condition due to lack of water in that area. In healthy condition pines can kill these insects but in stressed condition insect will effect the plant so if the number of beetle will decrease, the population of pines will increase in that area.
Answer:
Red light act as a inhibitor and hence causes delay in flowering
Explanation:
Through Periodism phenomenon, the regulation in exposure to daylight for a certain time period can delay or enhance the flowering of the "light duration"sensitive plant.
When "short day plants" are exposed to light between the essential long period of nights or dark period, the stage of flowering gets delayed.
Hence, chrysanthemums on being exposed to red light during their daily darkness period lead delay in flowering as red light act as an inhibitor.
