Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
Easy
how many times will it double
80/20=4
double 4 times
2*2*2*2=16
16 of them after 80 mins
Answer:
option C
option C
Explanation:
we know that gravity is strongest when two large objects are near each other--so, when the asteroid reaches point C (which is shown to be closest to the sun), the pull of gravity will be greatest.
We also know that the attraction/pull of gravity slows down objects, so, the asteroid will be going slowest at its point of strongest gravity--which we have determined to be point C
hope this helps! let me know if you need more explanation, have a lovely day :)

Answer:
During the telophase stage, the spindle fibres lengthens more and the nuclear membrane reforms to form the nuclei enclosing the separated sister chromatids. And, later followed by cytokinesis which involves the division of cytoplasm and yields the 2 daughter cells
