Answer:
The correct answer is - deuterostomes.
Explanation:
Duetorstomes eggs ,During embryonic development the zygote undergoes cleavage. Cleavage results is slitting into multiple cells where ease cell has the ability to develop into a complete embryo when isolated.
That would be the independent variable :)
Answer: The graph shows that chlorophyll a absorbs light principally around 420-450 nm and 650-680nm wavelengths
Explanation: Chlorophyll a is a pigment found in plants that traps light energy for use in photosynthesis. Chlorophyll a absorbs light mostly in the blue and orange-red wavelengths. This is shown in the graph, where the peaks are around the 400nm and 600nm wavelengths, corresponding to blue and red in visible light.
This absorption means the pigment is 'excited' by this light, sending into a higher state if energy which provides energy for the reactions of photosynthesis.
Answer:
anaphase
Explanation: The third phase is anaphase. This phase only takes about 0.8 percent of the cell cycle to complete, which is the shortest time required out of all the phases. During anaphase the sister chromatids, or the two identical parts of a chromosome, are pulled apart to opposite ends of the cell by the spindle fibers.
