We do not use carbon dioxide to fuel our blood cells. It is a waste.
Arteries move blood from the heart to the rest of the body.
Veins carry the blood to the heart to be oxidized.
"D" is not correct.
"B" is not correct.
We know that veins carry blood to the heart, lungs exhale carbon dioxide.
"A" is the correct answer.
I hope this helps!

<span>Anton van Leeuwenhoek learned to grind lenses ( 1668) and develop simple microscopes.
</span>
Leeuwenhoek heated the middle of a small soda glass rod , over a flame. On pulling apart the two ends, the glass rod elongated into thin whiskers .
Heating the end of this whisker resulted in a tiny high quality glass sphere. These glass spheres then became the lens of his microscope, with the smallest sphere providing the greatest magnification.
Leeuwenhoek's designs were very basic. The body of the microscope was a single lens mounted in a tiny hole on a brass plate. The specimen was then mounted on a sharp point that sticks up in front of the lens. It's position and focus could be adjusted by turning the two screws.
The entire instrument was about 3 to 4 inches long and had to be held up close to the eye, requiring good lighting and great patience to use.
Out of the following given choices;
<span>A)
</span>They are all of the same species.<span>
B) They all require the same type of food.
C) They are part of a community.
D) They are abiotic factors in a forest.</span>
The answer is C. A community is
the summation of all the species population interacting in a habitat/ecosystem.
These interaction between the population could include commensalism, predation,
symbiosis, parasitism, and etcetera.
Carbondioxide, being a green house gas has the property of trapping the heat from the sunlight and thus increasing the temperature of the place. As more and more rain forests are cut down and burned, there is an increase in this green house gas in the atmosphere thus leading to a steady increase in the temperatures.
As we look at the graphs that are given, we can see that the graph C shows the steady increase in the temperature as the time passes. Hence option C is the right answer
Answer
I’m pretty sure it’s all of the above
