Answer:
No, the 270 cm rope Clint has is not enough to do the job.
Explanation:
The height of tree where rope has to be tied = 180 cm
The distance of the stake from the base of the tree = 200 cm
We can say that the arrangement makes a right angle triangle, with the right angle situated at the base of the tree. The figure is attached below. Consult it for better understanding.
Length of the rope can be found by using Pythagoras theorem.
(Length of rope)² = 180² + 200²
Length of rope = 269 cm
As it is stated the additional 30cm of rope is required for tying from both ends. Total length of rope required is:
Total length of rope = 269 + 30
Total length of rope = 299 cm
As length of rope required is 299cm, the 270 cm rope Clint has is not enough to do the job.
Answer: True
Explanation: A mutation can help an organism survive in a particular environment. A mutation is a change in the nucleotide sequence of an organism. A mutation can be of three types - beneficial, harmful or neutral. A mutation is considered to be beneficial when it produces a variation that helps the organism to better adapt to its environment.
Answer:
There will be an increase in the level of nitrogen dioxide and a decrease in the level of ground-level ozone.
Explanation:
Ozone is a gas normally found in stratosphere, where it protects us from solar radiation. However, under certain circumstances, it can be formed on the ground level.
Conditions that have to be met in order for this to happen are existing of nitrogen oxides and volatile organic compounds (VOC) (both formed from the factories, industry and transport) and their reaction catalyzed by heat and light.
During dark, cold and cloudy days, due to the lack of heat and light from the Sun, formation of ozone will be decreased.
Also, this will enable building up of nitrogen dioxide, due to the same reason, leading to increased concentration.
