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.
The correct answer to this question is D.
A mitotic cdk-cyclin complex triggers entry into mitosis.
<span>
Cdk-cyclin complex consists of two units: cdk which is a cyclin-dependent kinase (catalytic subunit) and cyclin (regulatory subunit). This complex play a crucial role in cell cycle progression. There are different types of cdk-cyclin complex, for example, Cdk1-cyclin B1 complex triggers entry into mitosis (progresses the cell cycle through G2/M mitotic phase).</span>
