Answer:
Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry. ... In the wet type of acid deposition, these compounds combine with water vapor in the atmosphere to form highly corrosive sulfuric and nitric acids.
Explanation:
The accumulation of acids or acidic compounds on the surface of the Earth, in lakes or streams, or on objects or vegetation near the Earth's surface, as a result of their separation from the atmosphere. Acid deposition can harm the environment in a variety of ways, as by causing the acidification of lakes and streams, the leaching of minerals and other nutrients from soil, and the inhibition of nitrogen fixation and photosynthesis in plants.♦ The accumulation of acids that fall to the Earth dissolved in water is known as wet deposition. Wet deposition includes all forms of acid precipitation such as acid rain, snow, and fog.♦ The accumulation of acidic particles that settle out of the atmosphere or of acidic gases that are absorbed by plant tissues or other surfaces is known as dry deposition.
Answer:
Independent variable - vitamin gro and exercise routine.
Dependent variable - growth of children or nieces.
Explanation:
There are two variables present in an experiment called dependent and independent variables.
Independent variables are those variables which can be controlled in an experiment and dependent variables are those variables which are measured in the experiment under the influence of the independent variable.
In the given experiment, the independent variable will be vitamin gro and exercise routine and the dependent variable is the growth of children or nieces because vitamin gro and exercise routine can be controlled and growth of children is dependent on vitamin gro and exercise routine.
Answer:
All organisms use a source of energy for their metabolic activities. Some organisms capture energy from the sun and convert it into chemical energy in food (photosynthesis); others use chemical energy in molecules they take in as food (cellular respiration)Explanation:
