Answer:
The correct answer is A. The U-shaped body of water of the image is called oxbow lake.
Explanation:
An oxbow lake is a small U-shaped lake that forms in the curve of an abandoned meander of a fluvial channel. It is formed in general when the river cuts the neck of a meander to shorten its course, which causes the old channel to be quickly blocked, and then it is separated from the channel.
Answer: Its first one. An oxbow lake
Explanation:
The picture attached shows how an oxbow lake is formed. I hope my answer not only helps with your question but also helps you see how this is formed!
Good luck!
They are not valid because the student did not control all the variables that can affect plant growth
They are valid because the dependent variable caused a change in the independent variable.
They are not valid because the time frame to grow a plant is too short.
They are valid because the dependent variable caused a change in the independent variable.
Answer: Option C
Explanation:
The validity of a student’s result is basically based on how the dependent variable caused a change in the independent variable. A dependent variable is one which a scientist produce a variable and finds means to explain it in a proper way. An independent variable is one that is formed to compliment the dependent variable.
When the independent variable increases it causes decrease or increase in dependent variable. A intermediate or intervening variable is found which helps explain about the changes happening between the Independent and interdependent variable.
Answer:
Option (c) ''They are valid because the dependent variable caused a change in the independent variable'' is the correct answer.
Explanation:
The dependent variable is the one which is the center of observation. It is changed during the reaction and affected by it. When we measure the value of the reaction we always measure the dependent variable.
The independent variable is the one that is changed to cause the change in the value of the dependent variable. We can say that the dependent variable depends on independent for its reaction.
So dependent and independent variables are correlated with each other which tells the authenticity of the experiment.
Answer: 1500kg/m^3
Explanation: Assuming the cube was not large enough to float if it displaced 30cm^3 of water then it has a volume of 30cm^3. Density is just mass/volume so 45g/30cm^3 = 1.5g/cm^3. To convert this to kg/m we need to multiply by the conversion factors of the units. 1.5g/cm^3 • 1kg/1000g • 1,000,000cm^3/1m^3 = 1500kg/m^3.
because its edges mark a circle of high volcanic and seismic activity (earthquakes)
hope I helped!
