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.
A layer of soil with characteristic properties
Answer:
The artificial reef would decrease erosion of the coastline.
Explanation:
Artificial reefs are created in area where there is little uderwater topography or near established coral reefs to imitate or even substitute for natural coral reefs where they are absent or endangered due various factors which are mostly human in nature. The artificial serves to provide a habitat for marine organisms and ensure more biodiversity around the area by providing shelter from predation and surfaces for encrusting organisms such as corals and sponges to grow on. The growth of these lower level food chain organisms attract larger predator organisms thereby increasing the biodiversity in the area.
Artificial reefs are made from a variety of materials such as shipwrecks, construction debris, oil rigs, concrete, and any other man-made objects. Since reef structures protect shorelines against waves, artificial reefs would decrease the erosion of the coastline providing benefit to the people living along the coastline by preventing the destruction of beaches and coastal property,
