I believe its methane and carbon dioxide.... hopefully this works:)
a atmospheric rock is the "answer" sorry just need some points
The answer that your looking for is elastic deformation.
Hope this helps :)
Answer:
Option A, Fertilizers can maintain soil fertility and productivity into the distant future-even if the soil is eroding.
Explanation:
The top layer of the soil known as top soil is essential for its productivity because it contains essential nutrients such as phosphorus and potassium.
If this topsoil is lost, the inherent soil fertility is also lost. In order to restore the soil fertility, additional inputs in the form of fertilizers and manures are used.
Fertilizers help in restoring soil fertility but only if the essential subsoil material are present. In short it can be said that continuous soil erosion for a longer period of time will result into infertile land parcels whose fertility cannot be restored by fertilizers.
Hence, option A is correct
Answer:
Louis Pasteur demonstrated that cells can only arise from pre-existing cells.
Explanation:
The contributions of Louis Pasteur are one of the most remarkable in the history of humanity. Before Pasteur performed the experiments that revolutionized the cell theory, most people believed in the theory of <u>Spontaneous Generation</u>, which <u>stated living organisms could arise from non-living matter.</u>
However, in the 18th century, <u>Pasteur performed a series of experiments that disproved the theory of Spontaneous Generation</u>. By using using covered and non-covered flasks with broth, he demonstrated that cells were only able to grow in the broth if it was not properly covered, that is, if the air was exposed. This illustrated that cells couldn't arise from non-living matter but the opposite: cells can only arise from pre-existing cells. This was an extremely significant contribution to the cell theory.
