Answer:
The plant on the left does not accumulate significant photochlorophyll or carotenoids, so it will become very pale on the shoot tip, while the plant on the right will continue to grow upward as auxin is uniformly distributed around the tip of the right plant.
Explanation:
Phototropism is the orientation of a plant in response to light, either towards the source of light or away from light. Positive phototropism is growth towards light, while negative phototropism is away from light.
Auxin are substances that promote and regulate the growth and development of plants. Auxin escapes light making the area in the shade elongate more so the plant tip moves towards the light.
The people's way of living was i<span>nfluenced by climate, microclimate, latitude, altitude, and currents. Climate affects much of the economy of a certain community.

The fossils that provide information on the formation of an oxygen-rich atmosphere are the stromatilites from the Precambrian era. These are layered and columnar fossils consisting mainly of cyanobacteria which were the original life form back then. These bacteria took in carbon dioxide and produced oxygen by photosynthesis as early as 2.5 billion years ago (the earth is about 4.5 billion yrs old).
