What is the relative placement of the moon, earth and sun during a lunar eclipse?
1.The Sun, Earth and Moon are aligned with the Earth in the middle and the Moon furthest away from the Sun.
2.The Moon only partially covers the Sun during the eclipse.The Moon only partially covers the Sun during the eclipse.
3.Moon in perigee orbit; Moon moves a direct line between Sun and Earth; Moon in new moon phase.
4.The Earth's umbra fits inside the Moon creating an illuminated ring known as a annular eclipse.
The right answer to number four is
The Earth's umbra only cover a part of the Moon causing a circular shadow to pass across it.
A partial lunar eclipse happens when the Earth's umbra part moves across the Moon making a circular shadow across the Moon. An annular lunar eclipse is not possible because the Earth's umbra is always larger than surface of the Moon even if the orbits are in apogee.
The correct answer is : The rigidity of a cell wall causes plants to be sedentary.
Explanation:
Plant cells have an extraordinary organelle present outside of cell membrane known as a cell wall, which makes the cell more rigid and strong. The primary capacity of a cell wall is to provide structural support.
It additionally gives the plant a specific level of inflexibility, which permits it to become extremely tall without falling under its own weight. The drawback is the absence of versatility Which is the reason plants are inactive and incapable to move.
Thus, the correct answer is : The rigidity of a cell wall causes plants to be sedentary.
