Answer:
- E. Does photosynthesis performed by elodea remove CO2 from the water?
- F. Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea?
Explanation:
The tubes were placed under a growth light and as the elodea is growing, it would need photosynthesis to provide food. The color changes will therefore allow the students to see the effect photosynthesis has on the CO2 in the water by checking to see if the BTB turns blue which would mean that CO2 was removed by photosynthesis.
The students will also be able to see which process occurs faster in the tube with only elodea because the dominant color would show if cellular respiration occurs faster than photosynthesis or if the case is the reverse. For instance, if respiration is occurring faster, there will be more CO2 which would turn the BTB towards yellow, if photosynthesis is faster the BTB will turn towards blue and if the rates are similar, the BTB will remain green.

Answer:
Option (c).
Explanation:
Carbohydrates may be defined as the polymers of the sugars and one of the most important biomolecule of the living organisms. Carbohydrates plays an important structural and functional role.
Carbohydrates are always present on the exoplasmic surface of the plasma membrane. The are present in the association with the proteins and lipids as glycoproteins and glycolipids. These carbohydrates acts as the signaling molecule that display information on cell surface.
Thus, the correct answer is option (c).
Answer:
<em>The above statement is true.</em>
Explanation:
There are certain ethics which have to be followed during the scientific method of research. If these ethics are not followed, the scientific researches can be dangerous or not considered to be applicable.
One such ethic of scientific research is that when taking a biological sample from a research subject, the research subject should be properly guided about how the biological sample will be used for the research project. The research subject should be given knowledge about how the data obtained will be a part of the research object.
Answer:
Nucleotide
Explanation:
A Nucleotide is made out of a phosphate group, 5-ringed sugar, and a nitrogenous base, all of which are present in the image. Here the nitrogenous base appears to be adenine so it is the nucleotide derived from adenine.
