the answer is the first one: by producing random changes in an organism's genetic code
Answer:
D hydrosphere
Explanation:
Soil erosion is the removal of the top soil layer. Soil erosion is controlled by precipitation (e.g. rainfall) and wind action. Continuous water flow on soil surface supports microorganisms to perform biogeochemical cycles. The phenonmenon is primarlity controlled governed at the iterface of geosphere (soil) and hydrosphere (water).
On the other hand, atmosphere (layers of gases), biosphere (living organisms), cryosphere (frozen water) are not directly related to soil erosion.
Answer:
C, water pollution Contributes to water scarcity :>
Answer:
-DNA is a permanent storage place for genetic information
-DNA controls the synthesis of RNA (ribonucleic acid).
