Answer:
Through this experiment we study the process of photosynthesis.
• In the begining the leaf disks's tissue has oxygen, this allows them to float.
• Then, in the experiment we infiltrate the leaf disks with a solution that has bicarbonate, and as a result their density changes (it increases) and so the leaf disks sink.
• Once the disks are on the bottom and we direct the light to them the process of photosynthesis starts, being the bicarbonate the source of carbon for the process.
• As we know a product of the photosynthesis proces is oxygen, so when it is released into the leaf disks the overall density changes again and the disks rise.
So as we can see, in this experiment the purpose of the bicarbonate is being the source of carbon for the process of photosynthesis that occurs in the leaf disks.
D. ; Eukaryotic cells are bigger, younger, and more complex
Something with higher electric potential than the ground or a defined null or neutral point. Electrons flow from the positive point in a circuit. See also negative, null, and potential.
Codons that code for the same amino acid are termed synonyms, Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated.
Answer:
D. "always" cover the microscope when not in use.
Explanation:
when you are finished using a light microscope or any microscope in general you always need to put the cover back on it. Mostly, to protect it from any harmful bacteria, light etc. and to keep it clean and, from collecting dust.
