To try and help although thee aren't any answers i would say... if they were to literally conduct a field study such as this, much pollution would occur, Millions of fish would die as of plants also. And would over-all Lake Michigan would never be the same again.
Answer:
The correct answer is B photosynthesis stores energy,while cellular respiration releases energy.
Explanation:
Photosynthesis is an anabolic process that utilizes the atmospheric CO2 along with water molecule as a electron donor to generate glucose sugar and oxygen gas.Photosynthesis helps to store the light energy in form of chemical energy in the bonds of glucose molecules produced during photosynthesis..
on the other hand cellular respiration is a catabolic process that oxidizes glucose to generate energy in form of ATP along with CO2 and water as a byproduct.
Answer: Wet or dry environment.
Explanation:
<u>The independent variable is the variable that a researcher manipulates in an experiment in order to carry out a study on the incidence of the expression of the dependent variable.</u> Therefore, the independent variable is the one that changes or is controlled to see its effects on the dependent variable.
Researchers can then design a container with a wet or dry environment. But it's the pillbugs that are going to choose where to go and how long to spend in each part. So the time they spend in each part is a dependent variable since that cannot be controlled by the scientists conducting the experiment. Henceforth, the researches will just record this dependent variable without controlling it. But they can decide what to put in the container to make it wet or dry environment, or whatever they want to design. So wet or dry environment is the independent variable.
I would say energy myself, and this is because energy plays a key role in all of these. With trophic levels energy is being transferred amongst the levels. Food chain's is a map of how the energy is passed along the chain. Food web is a web of how energy is transferred, and this is why I would say energy is a keyword.
Answer:
In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
Hope it helps!
