Answer:
in aerobic respiration oxygen is needed and it occurs in mitochondria.
Plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar :)
Water plants in the solution are placed under a bright lamp. Thus, option "B" is correct.
<h3>Explain your answer briefly?</h3>
As we know adding carbon dioxide in as solution result in the change of its acidity this is result in the indicator to change from blue to yellow. In the question, it is asked that what factors from the given option will cause yellow indictor to blue which means what factors cause the solution to be alkaline from acidic.
Placing the green water plants in the solution under a bright lamp will cause the is utilizing and remove present carbon dioxide in the solution and leads the to blue color from the yellow color of the solution.
Thus, this could be the answer.
The question is incomplete, however, the missing part is given as below:
A. Yeast cells and sugar are placed in the solution. B. Water plants in the solution are placed under a bright lamp. C. Algae are placed in the solution and left in a dark room. D. A person blows air into the solution through a straw.

The correct answer is A
The scientist can determine that this nucleic acid is a DNA molecule, because it contains Thymine, which does not occure in the RNA molecule. The RNA molecule contains Adenine, Guanine and Cytosine just like the DNA, but unlike the DNA it contains Uracil, not Thymine.
Secondly, the scientist can say with certainty that this DNA molecule is surrounded by a nucleus based on the structure of the nucleic acid described. Only eukaryotic cells have ladder structure. The prokaryotic cells have circular DNA and do not have any organelles, like the nucleus. Therefore, from the ladder structure of the DNA the scientist can see that the cell has a nucleus.
