The major function of the contractile vacuole of amoeba is osmoregulation. The solute concentration found in the cell of amoeba's cytoplasm is more than the solute concentration in the freshwater that surround the external part of the organism, thus, water enter the cell through osmosis. The contractile vacuole collect the excess water and expel it through an opening in the cell membrane. By doing this, the contractile vacuole maintains the water balance in amoeba. This how the contractile vacuole normally operate.
In a situation where amoeba is placed in seawater, then water from the cell cytoplasm will rush out of amoeba cell, because of the higher salt content of the surrounding medium. The contractile vacuole will respond to the situation by increasing its contraction and pumping water out the cell in an accelerated manner, this will lead to the shrinking of the cell.
Answer:
A lunar eclipse can only occur when there is a full moon.
Explanation:
A lunar eclipse occurs when the Moon, Earth and Sun are aligned on a straight line. This alignment completely blocks the sunlight and moon is under the shadow of Earth. In this phase, moon often look red because of reflection of infrared radiations. This happens only where there is a full moon.
It is not possible to occur moon eclipse in any phase because if sunlight would reach the moon surface directly, it is not a moon eclipse Further, lunar eclipse can last upto a few hours because the shadow of Earth is greater because of its size compared to the moon's size and it takes a while until moon is completely out of that shadow. Lastly, a lunar eclipse doesn't create an eerie color in the sky rather a red color due to infrared radiations.
