The correct answer is: 2.5%
The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.
• Telomeres-ends of DNA with protective role (prevents shortening of DNA),
• Non-coding RNA genes-e.g. genes for tRNA,
• Gene regulatory sequences such as promoter, enhancers and silencers.
It cause a chain reaction and kills off the organisms
Answer:
option A is correct ......marine or aquatic
The answer is C. Soil is considered a non-renewable resource because it takes millions of years for soil to renew itself due to the long process of soil formation hence soil is easily degraded by human activity within a human lifespan. In the picture shown, the deforestation will cause the soil to be easily eroded by elements of erosion. This will lead to desertification of the region which will result in a domino effect on the rest of the forest.
