Answer:
Isotonic
Explanation:
A solution is isotonic to a cell if it has the same Concentration of dissolved particles as the cell. Water molecules move in and out of the cell at equal rate, so the cell size remains the same.
False. Both adding and taking away an organism affects a food chain.
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.
The earth's surface features are constantly changing in a process known as weathering and erosion. Weathering would happen when rocks would break physically like frost shattering while erosion happens when sediments and rocks are moved from one place to another by agents like water, gravity, wind and ice. These two occurrences are the cause of the constant change of the Earth's surface.<span />
Answer:
Burning fossil fuels moves carbon from the geosphere to the atmosphere.
Explanation:
- Fossil fuels such as coal, petroleum and natural gas are produced and stored in the geosphere. i.e. the part of the Earth that includes the Earth's interior, landforms, rocks and minerals.
- Fossil fuels, extracted from the geosphere are burned to generate energy.
- Combustion of fossil fuels releases the stored carbon into the atmosphere in the form of carbon dioxide.
