hypothesis: if i add the egg to vinegar then the shell will dissolve within 24 hours

0 hours:

the egg is shiny

smaller than a usual egg

16 centimeters

24 hours:

powdery

even smaller

17/2 centimeters

48 hours:

still powdery

the egg got bigger

18 centimeters

72 hours:

discolored

no shell

18 centimeters

evaluate the lab and data collected. what type of transport occurred in this lab? explain your answer, including evidence from your experiment to support your explanation.

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.

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

age range would be the answer
