B
Explanation:
6CO2+6H2O+energy from sun=C6H1206+6O2
C6H12O6 is a form of glucose
Answer: D.adding more shelter for frogs
Food chain can be defined as the linear series of food and energy distribution, in which one organism is consumed by the other in order to obtain nutrient and energy.
In the given situation a person wants to reduce the mosquito population, which is present as a primary and secondary consume in the pond food chain. By adding more shelters for frogs can reduce the population of frogs as the frogs are present as tertiary consumers in the pond food chain. These frogs will feed upon mosquitoes, and limit their population.
the answer to your scientifical question is D
Answer:
amount of copper
Explanation:
<em>The independent variable would be the amount of copper fed into the experimental rats.</em>
An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.
The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.
<u>Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.</u>
Answer:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
