A comet always points in the opposite direction of the comet hence why it’s called the tail
Answer:
In creature cells, if an answer that the cell is in has an equivalent measure of solute as within the cell does, the cell will continue as before size. On the off chance that there is more solute outside of the creature cell, the cell will recoil in light of the fact that the water will tail it out of the cell hypertonic arrangement. On the off chance that there is less solute outside of the creature cell, the cell will develop in light of the fact that the water will take after the more prominent solute within the cell hypotonic arrangement.

The Precambrian era envelopes the major bulk of the history of the Earth, beginning from the creation of the planet approx 4.5 billion years ago and terminating with the origination of composite, multicelled forms of life approximately 4 billion years after.
The Precambrian refers to the earliest of the geologic ages that are signified by the distinct layers of sedimentary rock. The Earth was about more than six hundred million years old when life started. The planet had cooled down from its native molten state, creating a solid crust and oceans formed by water vapor in the atmosphere.
At about three billion years ago, the atmosphere of the Earth was virtually devoid of oxygen. At approximately 2.4 billion years ago, oxygen was discharged from the seas as a waste product of photosynthesis by cyanobacteria. The levels of the gas slowly raised, attaining about 1 percent around two billion years ago.
Approximately 800 million years ago, the levels of oxygen attained about 21 percent and started to breathe life into more composite species. The oxygen-rich ozone layer was also created, protecting the surface of the Earth from the harmful solar radiation.
