The body contains about a trillion cells
Answer:
Chlorophyll "a"
Explanation:
The reaction centers of the photosystem have chlorophyll "a" molecules. The chlorophyll "a" that functions as a reaction center for the photosystem II has absorption maxima at 680 nm and therefore, it is called P680. The reaction center of photosystem I also have chlorophyll "a" molecules that have the absorption peak at 700 nm. The chlorophyll "a" molecules serving as reaction centers transfer the photoexcited electrons to a primary acceptor during the light-dependent phase of photosynthesis.
Answer:
Valence electrons, or the electrons that are farthest from the nucleus.
Mitosis only
OPTION A
Mitosis is simply the process of cell division.
Meiosis is the
process of producing gametes (eggs and sperm), which is important for sexual reproduction.
Answer: The cell is eukaryotic because it has chloroplasts. A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria.
