I believe it’s A. I know for sure it isn’t D.
Answer: A. Sediment
Eutrophication is a phenomena in which a water body gets enriched with minerals and nutrients frequently entered into water body due to run-off from the land, which facilitates dense growth of plants especially on the superficial layers of water body. Decaying organisms, fertilizers and pollution all add nutrients and minerals necessary for plant growth specifically remain floating on the superficial layers of water where plant growth takes place but sediments gets settled at the bottom of the water body, the minerals present in it remain settle at the bottom and hence, does not contribute to eutrophication.
Answer:
We can solve this by analyzing the choices and the relations between variables.
Notice that Kinetic Energy depends on the speed and the mass. Actually the Kinetic Energy is directly proportional to those variables, which means the more mass or the more speed, the more Kinetic Energy would be.
Having said that, Part I and Part II must have speed and mass as independent variable, because Kinetic Energy depends on them.
Then, in the third question, the answer is Kinetic Energy because that's the dependent variable in both cases Part I and Part II.
Just to remember, the Kinetic Energy is defined as
Where you can notice the relation between mass, speed and kinetic energy.
Therefore, the right answer are Mass (Part I), Speed (Part II) and Kinetic Energy (Part III).
Explanation:
There are many factors that increase the rate of reaction like concentration of reactants, atmosphere, presence or absence of catalyst, nature of reactants etc.
The factor usually does not increase the rate of reaction is lowering the temperature. But if we increase the temperature during reaction may be it increase the rate of reaction.
