<span>Tetraphenylcyclopentadienone has five conjugated aromatic rings. Its structure suggests that it is highly conjugated. With this structure, it absorbs the energy from wavelengths of colors other than violet and reflects the energy from violet wavelengths.</span>
Anaphase I begins when the two chromosomes of each bivalent (tetrad) separate and start moving toward opposite poles of the cell as a result of the action of the spindle. Notice that in anaphase I the sister chromatids remain attached at their centromeres and move together toward the poles.
<span>The most likely means by which the zoospores spread from one free-living amphibian to another is via the flagella. The flagella is a tail-like structure on zoospores that helps them to move.</span>
Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells
Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.
when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.
Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
