The answer is c enzymes are the produce Tom the building blocks of carbohydrates
Attached is an image that wherein the question is being referred from.
There are choices for this question namely:
A- gravity increased the downward flow of the trapped water
B- metabolism of the elodea plants absorbed CO2 from the water
C- heat from the light source caused the escape of dissolved gas
<span>D- light caused the elodea plants to photosynthesize, releasing O2 gas
</span>
The correct answer is that
light caused the Elodea plants to photosynthesize, releasing O2 gas. Choice A is not true as if gravity increased the downward flow of the water, then the model without light should have air accumulated in the test tube too. In Choice B, while it is true that the plant may have absorbed the dissolved CO2 in water, this does not explain why there is gas on top of the test tube. Choice C may only evaporate the water, not cause the escape of dissolved gases. In choice D, however, light caused the Elodea plants to perform photosynthesis releasing O2 gas compared to the other model without light wherein the plant cannot perform photosynthesis thereby not releasing O2 gas therefore no gas is seen on top of the test tube.
B because... Batteries are a source of chemical energy and chemical goes to electrical because the electrical energy goes through the circuits and then lastly, the electrical energy transforms into wind energy (mechanical energy)
To answer this question, you must know the blood types of Sheila and the man.
Well, I know logically that both life and environment change over time. So I think the answer would be C, studying fossils shows us that both life and environments change over time. Hope this helps.
