Answer:
A. Reduction in soil mass proved that plants get their food from the soil.
Explanation:
Plant take their food from the soil because in soil roots are present which absorb nutrients from the surrounding environment. The nutrients present in the soil comes from the decomposition of dead bodies of plants and animals and sometimes it is provided by the farmers in the form of fertilizers. The plant food contains nitrogen, phosphorus and potassium which is required in large amount for the better growth and development of the plant.
exposure to drugs causes mutations which produce drug-resistant populations of microbes.
<h3>What is the effect of using same type of drug?</h3>
Drug-resistant populations of microbes arise when the exposure to drugs causes mutations because this exposure produce resistance which leads to mutation in the organism. Due to this mutation, the drugs did not work on the organism anymore.
So we can conclude that exposure to drugs causes mutations which produce drug-resistant populations of microbes.

The answer would be protein it is easy to gain muscle that way.
<span>The situation shown consists of a picture with the sun emitting light energy; and a plant both absorbing carbon dioxide and emitting oxygen. The missing reactant in order for photosynthesis occur is water. Plants absorb water from the soil (through roots) and absorbs ligth energy from the sun (through leaves). The energy absorbed is used to split water molecules into H2 and O2. Then H2 combines with CO2 to form glucose. The answer is the option A) water.</span>
