Answer:
Cheek cells are eukaryotic cells
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.
I would say B). Hope this helps!
Hypertension or simply termed as high blood pressure is a condition
In the cardiac system where the blood pressure and transfer from one part of
the body to another exceeds the normal levels of the body. The heart is
strongly pumping blood throughout the body which is caused by either lipid
deposits in the vessels or in the heart itself.
Hence hypertension contributes to the conditions that
already exists such as stress, or existing disorders and worsen it.
