Answer:
D) Negative Geotropism
Explanation:
The stem growing upright is a typical example of negative geotropism.
Geotropism is the growth of a part of plant towards the pull of gravity.
- Gravity always pulls down on every object.
- When a body grows downward, then it is responding to a positive geotropism.
- When a body begins to grow upward, again gravity, then it is negative geotropism.
In this case, the negative geotropism is exhibited by some plant roots.
Also, some tree branches can also grow downward and this shows positive geotropism

For one, if you look at the example questions that define the Astronomy proposal, none of them are on topic for the Space Exploration site.
Astronomy is largely an academic site about the observation and
scientific study of celestial objects. Space Exploration SE is a much
more applied site about the engineering principles and challenges of
physical space exploration.
I would not suggest mixing the two.

Explosive eruptions tend to build up composite volcanoes.
A composite volcano evolved over tens of thousands of years as a result of several eruptions. The composite volcano is built up through eruptions, layer by layer, until it reaches heights of thousands of meters. Lava may have formed some layers, while ash, rock, and pyroclastic flows may have formed others. A composite volcano can also accumulate significant amounts of thick magma, which can clog up inside the volcano and force it to erupt violently.
Composite Volcano are fueled by a conduit system that accesses a magma reserve deep within the Earth. This magma can erupt either from a sizable core crater at the volcano's summit or from a number of vents scattered throughout the flanks of the composite volcano.
