Answer:
The fourth plant that receives pure water is the control group.
Explanation:
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, <em>the different concentrations of salty water that each plant receives</em>. The control group provides a reference point. It must be selected from the same population of the treatment groups. Both groups must be similar in every variable that might influence the results, <u>except for the study treatment.</u>
Answer:
Interesting assignment. I really hope this helps! -
Explanation:
You are going to use the chart where he graphed the data on his hamster's diet to dissect and identify, the parts of this scientific method.
TIP - try to think of this in a first-person perspective meaning try to think of this as you doing the experiment.
Hope this helped understand this assignment. :)
<u>Answer:</u>
During the "magma convection currents", the plate tectonics are pulled apart from each other. This is because if the "magma convection currents" flow in opposite direction, the plates present floating on the molten magma also float apart, causing divergent plate boundaries.
The plate tectonics are responsible for the movement of continental plates. The molten magma present inside the earth acts as a vast ocean on which the plates move as sheets. So if currents flow away from each other they take the plates along with them too, forming great rift valleys.
Answer:
Primary succession begins with soil formation. The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens. Lichens begin breaking down a rock.
The two major types of aquatic biomes is Freshwater and Marine. The major factor that differentiates between the two aquatic biomes is difference in Habitat.
The two major types of aquatic biomes is Freshwater and Marine.
Freshwater regions include rivers and lakes with comparatively low salt concentration.
Marine regions include Ocean, and Estuaries with comparatively high salt concentration.
The Habitat of the Freshwater and Marine life is the major differentiating factor between them.
The survival of fish is also dependent on the type of Freshwater and Marine environment.
Like, the marine water fishes can survive in a water concentration with high salt concentration.
The working of the organs of the aquatic organisms in Freshwater and Marine determines the concept of osmosis and various life important activities needed for the existence.
Fish in salt water need to maintain stable drinking conditions to maintain healthy life.
Freshwater organism finds easier to get adapted to the water environment. They are less sensitive as compared to marine water.
